Datalogic Matrix 120 troubleshooting guide: errors, faults and fixes

Short answer: According to Datalogic, this double flashing indicates a diagnostic error. Details of the error can be obtained from the Diagnostic page of the DL.CODE monitor, or by enabling the sending of diagnostic messages on the scanner's interfaces.

Likely cause

The Datalogic reference guide states that the Matrix 120 signals an error condition by flashing the STATUS light (red) and the READY light (green) simultaneously. The lights do not say which error it is: the list of error conditions (“Diagnostic Error Conditions”) can be read on the Diagnostic page of the DL.CODE monitor.

What to do

1. Connect a PC with DL.CODE to the scanner, preferably via Ethernet or USB (see Ethernet and USB).
2. Open the DL.CODE monitor and display the Diagnostic page: it shows the current error condition.
3. For the host to receive the information as well, enable the sending of diagnostic messages on the interfaces used.
4. Correct the cause indicated, then check that the two lights have stopped flashing together.

Short answer: The red STATUS light indicates a NO READ result: the scanner was triggered but did not decode any valid code. Check the position of the code, the focus and the symbology, then run the Setup function again.

Likely cause

According to the Datalogic reference guide, the STATUS light (red) indicates a no-read result (NO READ). By default, the scanner's output 1 is assigned to the same event: it activates when the code or codes expected during the reading phase have not been decoded.

What to do

1. Check that the code passes through the reading field, at the distance set by the focus position (see focusing).
2. If several codes are expected, remember that, by default, all of them must be decoded to obtain a good read (see several expected codes).
3. Measure the static read rate with Test mode (see Test mode).
4. If the rate remains low, go back through the procedure in the scanner does not read entry.

Short answer: The X-PRESS procedure failed and nothing was saved: the Setup calibration did not complete within about 5 seconds, or Learn did not complete within about 3 minutes. Present a single code, legible and correctly positioned, then run the function again.

Likely cause

The Datalogic reference guide describes two failures signalled by a long low beep. With Setup, if the scanner does not achieve image acquisition calibration within about 5 seconds, it exits the procedure without saving. With Learn, if automatic code learning is not complete within about 3 minutes, it likewise exits without saving. In both cases, the function's light stops flashing.

What to do

1. Place a single code at the reading distance that corresponds to the chosen focus position (see focusing).
2. Activate Focus/Aim mode to position the code relative to the aiming laser (see aiming).
3. For Learn, check that the symbology is one of those the function recognises (see Learn function).
4. Run the function again: hold down the X-PRESS button until the Setup (or Learn) light comes on, then release it.
5. If it succeeds, the scanner gives three high beeps and the light stops flashing.

Short answer: The scanner has entered its Loader program: the X-PRESS button was released too late during a reset attempt. Switch the power off and then on again to return to normal operation.

Likely cause

According to the Datalogic reference guide, if you hold the X-PRESS button during power-on and release it after the general flashing ends, when all the lights stay permanently on, the scanner enters the Loader program sequence instead of resetting its environment.

What to do

1. Switch off the power to the scanner, then restore it without touching the X-PRESS button: all the lights flash for one second and the scanner resumes normal operation.
2. If you wanted to reset the environment, start again, releasing and then pressing the button again during the flashing that lasts about 3 seconds (see resetting).

Short answer: First check that the focus position matches the distance of the code and that the scanner is tilted 10 to 20° relative to the label. Then run the X-PRESS button's Setup function with the code presented, and check the result in Test mode.

Likely cause

The Datalogic reference guide makes reading depend on three settings: the reading distance, set by the focus screw and the reading diagrams for the model (WVGA or 1.2 MP); the position of the scanner (“pitch” or “skew” angle of 10 to 20°, “tilt” rotation of 0°, with the code remaining entirely within the field of view); and finally the image and code parameters, calibrated by the Setup function or by the DL.CODE Automatic Setup.

What to do

1. Check the position of the focus screw on the back of the scanner and the actual distance of the code (see focusing).
2. Check the mounting: angle of 10 to 20° to the label, code entirely within the field (see shiny surfaces).
3. Activate Focus/Aim mode and position the code relative to the aiming laser (see aiming).
4. Run the Setup function: three high beeps confirm that the image parameters have been saved.
5. If the symbology is not yet configured, use the Learn function (see Learn function).
6. Check the read rate in Test mode (see Test mode).
7. For moving products, also check the exposure time (see fast conveyor).

For several symbologies, several image settings or code quality grading (Code Grading), Datalogic points to the DL.CODE manual configuration (Manual Setup) rather than the Automatic Setup.

E) (official documentation).

Short answer: The Matrix 120 focus is manual and is adjusted with a 2.5 mm hex key on the screw on the back of the scanner. Datalogic has calibrated three positions: 45, 70 and 125 mm on WVGA models, 45, 80 and 125 mm on 1.2 MP models. Choose the one that matches the distance of the code.

Likely cause

According to Datalogic, the scanner is factory-calibrated at three focus positions, but the adjustment range is continuous to allow fine-tuning. A code placed outside the depth of field of the chosen position gives a blurred image and a no-read.

Caution: Do not turn the screw beyond the limits of the focus scale: Datalogic warns that the mechanism could be damaged.

What to do

1. Measure the distance between the reading window and the code.
2. With a 2.5 mm hex key, turn the focus adjustment screw on the back of the scanner to the position closest to this distance.
3. Fine-tune between the marks if necessary: the range is continuous.
4. Run the Setup function again, then check in Test mode (see Test mode).
5. Once the application is set up, stick one of the focus locking labels supplied (five single-use adhesive labels) over the screw so that it can no longer be changed.

Wide-angle (WA) models without a polariser also use the 45, 80 and 125 mm positions, according to the quick start guide.

Short answer: This is normal: the aiming laser cross is slightly offset from the centre of the field of view. Datalogic asks you to place the code a few millimetres to the left of the cross (8 mm according to the quick start guide), vertically centred.

Likely cause

The Datalogic reference guide describes Focus/Aim mode: the aiming laser comes on and the Aim light flashes. The aiming pattern is vertically centred but offset a few millimetres to the right of the centre of the field of view, hence the instruction to place the code to the left of the cross.

Caution: The Matrix 120 is a Class 1M laser product (IEC 60825-1): do not look at the beam through an optical instrument. Datalogic asks you to switch off the power before opening the device for installation or maintenance.

What to do

1. Power on the scanner: all the lights flash for one second, then the blue POWER ON light stays on.
2. Hold down the X-PRESS button until the Aim light comes on, then release it: the aiming laser comes on.
3. Place the code at the reading distance for your model, a few millimetres to the left of the aiming cross and vertically centred.
4. Press the button once to exit: the laser turns off after a short delay.

E) (official documentation).

Short answer: In Test mode, the five X-PRESS lights show the good read rate for the code presented as a bar graph. If only the red STATUS light flashes, no code is being read. Pressing the button exits Test mode, which also stops on its own after three minutes.

Likely cause

According to Datalogic, Test mode is used to check static reading performance once focusing and the Setup function have been carried out.

What to do

1. Hold down the X-PRESS button until the Test light comes on, then release it.
2. Present the code: the higher the bar graph rises, the higher the good read rate.
3. If only the red STATUS light flashes, redo the focusing and the Setup function (see scanner does not read).
4. Press the button once to exit Test mode; by default, it closes on its own after three minutes.

Short answer: The yellow TRIGGER light comes on when the external trigger input is active. If it stays off, check the wiring and power supply of the photocell on input 1 (I1A/I1B) and the reading mode (One Shot or Phase). In DL.CODE, the input line type must be set to NPN, whether the wiring is NPN or PNP.

Likely cause

The Datalogic reference guide states that in One Shot or Phase mode, an external trigger, for example a photocell, activates reading when the object enters the reading zone. Input 1 (External Trigger, terminals I1A and I1B, opto-isolated and polarity-insensitive) acts as the acquisition trigger in One Shot and as the start/stop command for the reading phase in Phase mode. Its active state is chosen in the software and a debounce filter is active by default. In Continuous mode, the scanner does not wait for a trigger.

Caution: According to Datalogic, the voltage on the Vdc/GND terminals of the CBX box powers the input sensor directly without going through the CBX switch: switch off the power before working inside the box. Do not exceed 30 Vdc between the input terminals.

What to do

1. In DL.CODE, check the chosen reading mode (Continuous, One Shot or Phase Mode) and its parameters in the Reading Phase panel.
2. Check the photocell wiring on I1A/I1B and its power source (scanner power or external), using the PNP or NPN diagrams in the guide.
3. Set Input Line Type to NPN for each input used; the hardware wiring itself can be NPN or PNP.
4. Check the active level of the input and, if triggers are missed or multiplied, adjust the Debounce Filter parameter.
5. Pass a product through: the yellow TRIGGER light should come on for as long as the input is active.

Input 2 (I2A/I2B) acts as a second trigger in Phase mode, or as the command for storing the reference code when the Match Code option is active.

Short answer: The code moves during exposure and the image becomes blurred. Datalogic sets a simple rule: the exposure time must not exceed the time the code takes to travel the width of one module. Reduce the exposure time or the line speed, taking the illumination mode into account.

Likely cause

The Datalogic reference guide calculates the maximum line speed using the formula LS max = X / Texp, where X is the module size of the code and Texp the exposure time. Example from the guide: with Very High Power Strobe illumination, an exposure time of 200 µs and a module of 0.254 mm, the maximum speed is about 1,270 mm/s. Lower code/background contrast and increasing code rotation, from 0 to 45°, reduce the permissible speed.

Caution: In Power Strobed illumination mode, the scanner automatically limits the exposure time to protect the LEDs from overheating, according to Datalogic.

What to do

1. First check in Test mode, with the product stationary, that the code is read correctly (see Test mode).
2. Calculate the maximum exposure time: Texp max = X / LS (module size divided by line speed).
3. In DL.CODE, set the exposure time below this value.
4. For linear codes, if possible move the code parallel to the bars: the permissible speed is higher.
5. After any change to the internal illumination mode, check the exposure time again.

The Disabled illumination mode turns off the internal LEDs; it is used when the application uses external illumination.

Source: Maximum Line Speed and Exposure Time Calculations (opens in a new window) – Matrix 120 Product Reference Guide (Datalogic) (official documentation).

Short answer: A scanner placed directly facing the code receives the reflection of its own illumination. Datalogic recommends tilting the scanner 10 to 20° relative to the label. For mounting at 90° above a reflective surface, Datalogic offers a polarised version.

Likely cause

The quick start guide asks for an angle of 10 to 15° to the code to avoid direct reflections; the reference guide gives an ideal range of 10 to 20° for the angle (pitch or skew), with a rotation (tilt) of 0°. The Datalogic product page presents the polarised model as intended for mounting at 90° above reflective surfaces.

What to do

1. Tilt the scanner 10 to 20° relative to the code surface using the mounting bracket.
2. Keep the entire code within the field of view: rotation of the code does not prevent reading as long as it stays within the field.
3. Run the Setup function again to recalibrate the image after changing the angle.
4. If the scanner must remain perpendicular to a shiny surface, find out about the polarised version (PLRZ) or the 90° deflection mirror available as an accessory.

Short answer: By default, when several codes are expected, DL.CODE combines them with a logical AND: all must be decoded to obtain a good read. If a single code is enough, group them in the same XOR (exclusive OR) box in Good Read Setup.

Likely cause

According to the Datalogic reference guide, a good read depends on the type of data collection chosen (Code Collection, Code Combination, Presentation or Match Code) and on the logic between the expected codes, which is a logical AND by default. The content sent to the host then depends on the message formatting (Data Formatting).

Caution: Datalogic advises against having the same signal trigger several events on the same edge, or the same channel trigger several with the same string: these events then occur in a random order and the scanner may behave unpredictably.

What to do

1. In DL.CODE, open Good Read Setup and check the type of collection chosen; types unavailable in the current reading mode are greyed out.
2. To obtain a good read as soon as one code is decoded, drag the code icons into the same XOR box, then delete the box left empty.
3. To return to a logical AND, add a box with the Add icon and drag the codes into it.
4. In Data Formatting, check that the message (Message 1, Message 2…) contains the fields expected by the host, in the correct order.
5. Save the configuration to permanent memory (see lost settings).

Source: Step 5 - Device Configuration (Good Read Setup; Data Formatting) (opens in a new window) – Matrix 120 Product Reference Guide (Datalogic) (official documentation).

Short answer: A greyed-out device has been detected but is not on your local network. Click the scanner's spanner icon, identified by its serial number, and give it an IP address, subnet mask and gateway compatible with your network, provided by your network administrator.

Likely cause

The Datalogic reference guide explains that DL.CODE displays all the devices on the local network, with those outside the LAN appearing greyed out. Ethernet models (part numbers xxx-x1x) have an on-board auto-crossover Ethernet interface: no crossover adapter is needed. The yellow NET light indicates an active Ethernet connection.

Caution: Datalogic asks that Ethernet and the data port only be connected to networks whose routing remains inside the plant or building.

What to do

1. Check that the yellow NET light is on; if not, check the M12 Ethernet cable (CAB-ETH-M0x).
2. In DL.CODE, identify the scanner by its serial number.
3. Click the spanner icon to open the Device Environment Configuration window.
4. Enter the IP address, subnet mask and gateway suited to your network, then click OK.
5. The scanner reappears in colour in Online Devices with its new address: double-click it to select it.

With PROFINET IO, do not assign an address in the 169.254.x.x range, which is reserved according to Datalogic.

E) (official documentation).

Short answer: The Matrix 120 USB needs the “Matrix USB Driver”, which must be ticked when installing DL.CODE; restarting the PC is then recommended. Click Getting Started: the scanner appears in Online Devices, not in the list of serial devices.

Likely cause

According to the Datalogic reference guide, serial + USB models (part numbers xxx-x0x) connect to the PC with the CAB-1021 cable. The USB driver creates a virtual Ethernet connection whose IP address is fixed and cannot be changed; this is why the USB scanner has no spanner icon. A USB hub must supply 500 mA per port.

What to do

1. If the driver is missing, run the DL.CODE installation again, ticking “Matrix USB Driver” (and “RS232 Serial Port Driver” if needed) in the welcome window, then restart the PC.
2. Connect the scanner with the CAB-1021 cable (or CAB-1051 if you use inputs/outputs), directly to the PC or to a hub capable of supplying 500 mA per port.
3. Wait for the scanner to finish starting up, then click Getting Started in DL.CODE.
4. Identify the scanner by its serial number in Online Devices and double-click it.

Source: Step 4 - Installing DL.CODE Configuration Program; Step 4B - USB Device Discovery; Typical Layouts (USB Connection) (opens in a new window) – Matrix 120 Product Reference Guide (Datalogic) (official documentation).

Short answer: Serial device discovery is disabled by default in DL.CODE. Enable “Enable Serial Device Discovery” in Options > UI Settings, set the communication parameters (115,200 bit/s by default), then click Getting Started.

Likely cause

According to Datalogic, serial communication is supported from DL.CODE 1.4.0 onwards but is not enabled by default. It is slower and limits some DL.CODE functions: Datalogic advises configuring the scanner via Ethernet or USB when possible. The main serial port operates in RS232 or RS422 Full Duplex, from 2,400 to 115,200 bit/s.

Caution: According to the quick start guide, the RX- line must not be left floating (unconnected).

What to do

1. In DL.CODE, open Options > UI Settings, then Global Settings and the Find Devices tab.
2. Tick Enable Serial Device Discovery and choose the serial parameters for your application (default baud rate: 115,200).
3. Preferably leave the Enable Automatic Device Discovery option unticked: it tries all baud rates (no parity, 8 data bits, 1 stop bit) and makes the search much longer.
4. Click OK, then Getting Started, and open the Serial Devices tab.
5. Check the RS232 wiring on the PC side: on a 9-pin connector, pin 2 = RX, pin 3 = TX, pin 5 = GND; on a 25-pin connector, pin 3 = RX, pin 2 = TX, pin 7 = GND.

Once a fieldbus has been configured via the CBX500 box, the main serial port is no longer available (see fieldbus).

E) (official documentation).

Short answer: This is normal with a fieldbus connection via the CBX500 box: the COM light stays on because of the master's cyclic polling. On Ethernet models, EtherNet/IP, PROFINET IO and Modbus TCP work without an external module.

Likely cause

The Datalogic reference guide states that the COM light indicates active communication on the main serial port and that it stays on permanently with a fieldbus connection via CBX500, due to polling. In this architecture, the scanner is a slave node: a fieldbus card housed in the CBX500 (for example BM300 Profibus or BM400 DeviceNet) transmits the data to the host, which can also control the other CBX inputs/outputs through the scanner.

What to do

1. Identify the type of connection: fieldbus via CBX500, or native Ethernet industrial protocol (EtherNet/IP, PROFINET IO, Modbus TCP Client) on an Ethernet model.
2. Before configuring the fieldbus, make the other configuration changes via Ethernet or USB: once the fieldbus is configured, the main serial port is no longer available.
3. With PROFINET IO, do not use an address in the reserved 169.254.x.x range.
4. On an Ethernet model, also check the configured communication channels: TCP Client, TCP Server, UDP or FTP Client.

Short answer: By default, output 1 signals a no-read (No Read) and output 2 a good read. Check the output assignment in Output Setup, the line type set to NPN in DL.CODE and the electrical limits: 30 Vdc and 40 mA continuous maximum.

Likely cause

According to the Datalogic reference guide, the outputs are fully programmable: activation and deactivation events, timeout, or both. Connected via the CBX box, they are opto-isolated and polarity-sensitive; their line type (Output Line Type) must be set to NPN for each output used.

Caution: If the outputs are powered by an external source, Datalogic asks you to keep the same voltage levels as those of the Matrix 120. Switch off the power before any work inside the CBX box.

What to do

1. In DL.CODE, open Output Setup and check the event assigned to each output (default: output 1 = No Read, output 2 = Good Read).
2. Set Output Line Type to NPN for each output used.
3. Check the wiring (PNP or NPN diagrams, powered by the scanner or externally) and the polarity.
4. Respect the limits: 30 Vdc maximum, 40 mA continuous or 130 mA pulsed.
5. Save the configuration to permanent memory.

Short answer: At power-on, all the lights should flash for one second, then the blue PWR light stays on. If it stays off, check the source: 5 to 30 Vdc for a direct connection, 10 to 30 Vdc via a CBX box, supplied by a computer or a UL-listed LPS or Class 2 power supply.

Likely cause

The Datalogic reference guide states that the PWR light (blue) indicates that the scanner is powered, and that all the lights flash for one second at start-up or restart. The quick start guide sets the supply voltage at 5–30 Vdc, or 10–30 Vdc with a CBX box.

Caution: According to Datalogic, installation is reserved for qualified personnel. Switch off the power before opening the CBX box or the device.

What to do

1. Check the cable connected to the scanner's M12 connector: CAB-1011 to the CBX box, CAB-1021 or CAB-1051 for USB.
2. With a CBX100 or CBX500 box, measure the voltage on the Vdc/GND terminals (10 to 30 Vdc) and check the CBX power switch.
3. With USB, connect the scanner directly to the PC or to a hub capable of supplying 500 mA per port.
4. Connect the scanner chassis to the installation's earth with a flat copper braid shorter than 100 mm, and the CBX “Earth” terminal to a good earth.
5. Power on again and check that all the lights flash for one second.

When to call a technician: the scanner stays off with a compliant power supply: according to Datalogic, only qualified and authorised personnel may access the internal parts.

E) (official documentation).

Short answer: Press once: the STATUS light responds. Then hold the button down: the lights cycle in the order Test, Focus/Aim, Setup, Learn; release on the function you want. A single press exits the current function.

Likely cause

According to the Datalogic reference guide, the scanner's button is software-programmable and by default launches the X-PRESS interface, which gives access without a PC to four functions: Test, Focus/Aim, Setup and Learn. Successful Setup or Learn is confirmed by three high beeps. For Learn, cancellation by a press takes effect after a short delay.

What to do

1. Press the button once: the STATUS light gives visual feedback.
2. Hold the button down: the lights come on in turn for Test, Focus/Aim, Setup then Learn.
3. Release the button when the light for the function you want is on.
4. To exit a function, press the button once.
5. If the button no longer launches X-PRESS, check in DL.CODE the function assigned to it: it is programmable.

E) (official documentation).

Short answer: The X-PRESS button's Learn function only saves a single symbology: each new learning operation replaces the previous one. To read several codes, use the DL.CODE Auto-Learn function.

Likely cause

According to Datalogic, Learn automatically detects and configures an unknown code (type and length) and saves the image processing and decoding parameters. It does not recognise postal codes, Pharmacode, MSI, Standard 2 of 5 or Matrix 2 of 5.

What to do

1. Present a single code, of the symbology to be learned, at the correct reading distance.
2. Hold down the X-PRESS button until the Learn light comes on, then release it: the light flashes during learning.
3. If it succeeds, the green spot activates, the light stops flashing and the scanner gives three high beeps.
4. With no result after about 3 minutes, a long low beep signals failure (see long low beep).
5. For several symbologies, or for those that Learn does not recognise, configure the codes in DL.CODE.

The guide specifies that the “Grade A Barcode Test Chart” cannot be used to set the Code 128 symbology.

Short answer: Hold the X-PRESS button during power-on until all the lights flash together, for about 3 seconds. During this flashing, release and then press the button again: three high beeps confirm that the environment parameters, including the IP address, have returned to their default values.

Likely cause

The Datalogic reference guide presents this optional procedure, “Reset Reader to Factory Default Environment”, in the quick setup. It resets the scanner's environment parameters, including the default IP address. Saved configurations remain in memory, but the Default configuration becomes the start-up configuration.

Datalogic procedure

1. With the scanner powered off, hold down the X-PRESS button.
2. Power on the scanner while keeping the button pressed, until all the lights flash simultaneously for about 3 seconds.
3. During this flashing, release the button and then press it again.
4. The scanner gives three high beeps and switches to operating mode after a few seconds.
5. If necessary, reconfigure the IP address (see Ethernet) and reselect your working configuration, still in memory, in DL.CODE.

If you release the button after the flashing ends, when all the lights stay solid, the scanner enters the Loader program: switch the power off and on again (see Loader mode).

Short answer: At first launch, DL.CODE requires authentication: login with a Datalogic account, account creation, offline access with an activation file or a 15-day trial. If no choice is made, at the end of the trial or if the activation file does not work, the software closes.

Likely cause

The Datalogic reference guide specifies that login is mandatory. Offline, DL.CODE displays a machine identifier (Machine ID) to be sent to Datalogic technical support, which provides an activation file. The 15-day trial can neither be extended nor reused, even with another version of DL.CODE. The guide also gives the PC requirements: Windows 8 or 10, 1 GB of RAM, a 100 Base-T Ethernet port; Windows XP, Windows 7 and Windows Embedded are not supported.

What to do

1. Download the DL.CODE mini-DVD .zip file, extract it keeping the folder structure, run start.hta then the Install DL.CODE link.
2. For a serial + USB model, tick “Matrix USB Driver” and, if needed, “RS232 Serial Port Driver” in the welcome window, then restart the PC.
3. At first launch, choose Login (existing Datalogic account), Sign up (account creation), Offline Login or Start trial.
4. Offline: click Offline Login, note the Machine ID displayed by your version of DL.CODE, send it to Datalogic technical support, then load the file you receive with Load Activation File.
5. During the 15-day trial, register online or offline before it expires.

When to call a technician: the activation file does not work: DL.CODE displays an error and closes, and Datalogic asks you to contact its technical support.

Short answer: Changes made in DL.CODE remain in temporary memory until they are saved. Use “Save on Device” to write them to permanent memory, then make a backup to file.

Likely cause

According to the Datalogic reference guide, the configuration must be saved from temporary memory to permanent memory, which overwrites the previously saved version; for a lengthy configuration, Datalogic advises saving often. The Default configuration can be neither modified nor deleted, and Datalogic guarantees at least 50 configurations in permanent memory (without scripts or with scripts of fewer than 2,048 characters). An environment reset with the X-PRESS button also makes the Default configuration active at start-up.

What to do

1. In DL.CODE, click Save on Device after each set of settings.
2. Give the new configuration a name or overwrite an existing configuration: the Default configuration remains intact.
3. Once the configuration has been checked, run a backup to file from DL.CODE.
4. If the scanner starts on the Default configuration after a reset, reselect your configuration in the Open Device Configuration window: it is still in memory (see resetting).

Short answer: Datalogic asks you not to drop the scanners or let them knock against each other, not to adjust them by striking the scanner or its bracket, not to weld them in place and not to spray paint nearby. In hot environments, use a metal mounting bracket.

Likely cause

The Datalogic reference guide describes the Matrix 120 as a precision product: it withstands vibration and shocks once correctly installed, but must be handled with care before and during installation. Welding can cause electrostatic or thermal damage and harm the reading window; paint spray can also damage it. The quick start guide gives an operating range of 0 to 45 °C and an IP65 protection rating.

Caution: According to Datalogic, only qualified and authorised personnel, trained in optical and electrical risks, may access the internal parts; any change to the intended use of the product is prohibited.

What to do

1. Handle each scanner separately, without letting them knock against each other or fall.
2. Adjust the position by loosening the bracket, never by striking the scanner or its mount.
3. Do not weld the scanner and do not spray paint near the reading window.
4. In hot environments, mount the scanner on a metal bracket and stay within the 0 to 45 °C range.
5. After any mechanical work, check reading in Test mode (see Test mode).
