Toshiba B-EX6 troubleshooting guide: errors, faults and fixes

Short answer: The printhead block was opened in online mode, or a feed or print was started with the head open. Lower the printhead block, turn the head lever to the locked position, then press RESTART if a print job was in progress.

Likely cause

The Toshiba manual distinguishes two cases: the printhead block is open in online mode; a feed or print was attempted while the printhead block was open. The key operation specification states that this message also appears if a feed or print is started with the head open during the “ribbon near end” state.

Caution: Keep your fingers clear when opening or closing the cover and the printhead block; the head is hot just after printing (Toshiba warnings).

What to do

1. Lower the printhead block and put its holder plate back in place.
2. Turn the head lever to the locked position (Lock), then close the top cover.
3. If the error appeared during a feed or print, press RESTART to resume.
4. If the message does not clear with RESTART, switch the printer off and on again; Toshiba states that the print data in memory is then erased.

Short answer: The roll has run out or is incorrectly loaded, the media sensor is not positioned over the gap or the black mark, its threshold is not set, or the media is slack. Reload the media, adjust the sensor position, then press RESTART.

Likely cause

The Toshiba manual lists five causes: media run out; media incorrectly loaded; media sensor position not adjusted; sensor not calibrated for the media in use; slack media.

Caution: Do not touch moving parts: reload the media only once the printer mechanism has come to a complete stop. The head may be hot just after printing: do not touch its components, and keep your fingers clear when closing the cover (Toshiba warnings).

What to do

1. If the roll has run out, load a new one and press RESTART.
2. Otherwise, reload the media correctly (straight path, media centred under the head) and press RESTART (see loading labels).
3. Adjust the sensor position: gap sensor at the centre of the gap between two labels, or black mark sensor at the centre of the mark. Press RESTART.
4. Take up the slack in the media.
5. If the error persists, set the detection threshold (see calibration).

When to call a technician: if setting the threshold does not clear the error, Toshiba asks you to switch the printer off and call an authorised technician.

The manual states that a black mark sensor that is not centred on the mark can cause a PAPER JAM or NO PAPER error.

Short answer: The media is stuck or incorrectly loaded, or the printer cannot find the start of the labels: wrong sensor selected, sensor misaligned, format different from the one programmed, or threshold not set. Remove the stuck media, clean the head and the platen, reload and press RESTART.

Likely cause

Toshiba lists: media stuck or not feeding smoothly; media incorrectly loaded; wrong media sensor selected; black mark sensor misaligned with the mark; media size different from the programmed size; sensor not calibrated for the media.

Caution: Do not use any tool that could damage the printhead. Keep watches and rings away from the edge of the head: its element is easily damaged by impact (Toshiba instructions).

What to do (including the official procedure for removing jammed media)

1. Open the top cover, turn the head lever to FREE, open the holder plate and then the printhead block.
2. Remove the ribbon and the media, then clear the jammed media without using a sharp tool.
3. Clean the printhead and the platen, and remove any dust or foreign matter.
4. Reload the media correctly and press RESTART.
5. If the sensor does not match the media, switch the printer off and on again, select the sensor suited to the media type and resend the job.
6. If the programmed size differs from the media loaded, load the correct media or correct the size, then resend the job. If the error persists, set the threshold (see calibration).

When to call a technician: if the error persists after these steps, Toshiba asks you to switch the printer off and call an authorised technician; also contact one if the cutter jams frequently.

Cutter jams can be caused by wear or by adhesive residue from the labels: Toshiba asks you not to use unspecified media with the cutter.

Short answer: The ribbon has run out: the ribbon sensor, at the back of the printhead block, has detected its end. Load a new ribbon, remove any slack, then press RESTART.

Likely cause

According to Toshiba, the ribbon has run out. The ribbon sensor located at the back of the printhead block detects the end of the ribbon, displays NO RIBBON and turns on the ERROR light.

Caution: Do not touch moving parts: load the ribbon only once the printer mechanism has come to a complete stop. Let the head cool down and do not touch its components, which are sensitive to static electricity (Toshiba warnings).

Official ribbon loading procedure

1. Open the cover, turn the head lever to FREE, then open the holder plate and the printhead block.
2. Slide the ribbon stoppers to the ends of the shafts, then place the ribbon on the two shafts, leaving some slack between the rolls. The stopper clips must face the inside of the printer.
3. Centre the ribbon by moving the stoppers along the shafts.
4. Lower the printhead block and put the holder plate back.
5. Wind the leader onto the take-up core until the ribbon can be seen at the front of the printer, to remove any slack.
6. Turn the head lever to the Lock position, close the cover, then press RESTART.

Before the ribbon runs out, the “ribbon near end” icon flashes on the display and the ERROR light flashes (500 ms on, 500 ms off). Detection is based on the diameter of the remaining ribbon: about 38 mm for 30 m and 43 mm for 70 m, according to Toshiba.

Short answer: The ribbon is not feeding correctly, is not loaded or is torn, or the ribbon sensor is faulty. Remove the ribbon, check it, replace it if necessary and reload it without any slack.

Likely cause

The Toshiba manual lists three causes: ribbon not feeding correctly; ribbon not loaded; faulty ribbon sensor. The key operation specification adds a fault in the ribbon motor torque sensor, and a jammed or torn ribbon.

What to do

1. Remove the ribbon and check its condition; replace it if it is damaged.
2. If no ribbon is loaded, load one (see loading the ribbon).
3. Remove any slack before printing: according to Toshiba, a wrinkled ribbon degrades the print.
4. Press RESTART.

When to call a technician: if the error persists or if the ribbon sensor is faulty, Toshiba asks you to switch the printer off and call an authorised technician.

Only use a ribbon with thermal transfer media: Toshiba asks you not to load a ribbon with direct thermal media.

Short answer: The printhead has overheated. Switch the printer off and let it cool down for about 3 minutes; this error does not clear with RESTART.

Likely cause

According to Toshiba, the printhead is overheating.

What to do

1. Switch the printer off.
2. Let it cool down for about 3 minutes, then switch it back on.
3. Check that the ambient temperature stays within the operating range specified by Toshiba: 5 to 40 °C.

When to call a technician: if the error persists after cooling down, Toshiba asks you to call an authorised technician.

During long continuous print runs, the printer may also slow down to let the head cool: see intermittent printing.

Short answer: The printer has detected a printhead problem: a broken heating dot or a drive circuit error, according to the key operation specification. The manual prescribes replacing the head, an operation it does not describe: call in an authorised technician.

Likely cause

The owner's manual indicates a printhead problem; the key operation specification states: a broken dot on the thermal head or an error in the head drive circuit.

Caution: Do not touch the head element with bare hands: static electricity can damage it (Toshiba instruction).

What to do

1. Press RESTART: according to the message table, this error is one of those that RESTART can clear.
2. If the error does not clear, switch the printer off and on again (the print data in memory is then lost).
3. If the error comes back, the printhead needs to be replaced.

When to call a technician: replacing the head is not described in the owner's manual; Toshiba asks you not to attempt to repair the printer and to contact an authorised Toshiba Tec technician.

Short answer: Toshiba links this error to electrical interference (noise sources, nearby cables, power cord not earthed, shared socket) or to a problem with the host software. Move the printer away from noise sources, power it from a dedicated earthed socket, then switch it off and on again.

Likely cause

The manual lists: printer used near a noise source, or power cords of other equipment near the printer or its interface cable; power cord not earthed; power source shared with other equipment; host computer software in error. INTERNAL COM ERR indicates a hardware error in the internal serial interface.

What to do

1. Move the printer and its interface cables away from noise sources and from the power cords of other equipment.
2. Earth the power cord and give the printer a dedicated power source.
3. Check that the host computer and its software are working correctly.
4. Switch the printer off and on again: this error does not clear with RESTART.

When to call a technician: for INTERNAL COM ERR, for any message not listed or for an error that persists after restarting, Toshiba asks you to switch the printer off and call an authorised technician.

Short answer: These messages indicate a write error, a formatting error or a lack of space in the flash memory or on the USB memory stick, or a fault in the backup EEPROM. The Toshiba manual asks you to switch the printer off and on again.

Likely cause

MEMORY WRITE ERR.: write error in the flash memory or on the USB memory stick. FORMAT ERROR: erase error during formatting. MEMORY FULL: insufficient capacity, the data is not saved. EEPROM ERROR: failure to read or write the backup EEPROM.

What to do

1. Switch the printer off, then switch it back on: these errors do not clear with RESTART.
2. If the message comes back, switch the printer off and call an authorised technician, as the manual specifies for unresolved problems.

When to call a technician: if the error reappears after restarting, Toshiba asks you to switch the printer off and call an authorised technician.

Short answer: First place the sensor at the centre of the gap between labels, or of the black mark. If pre-printed labels are still not detected properly, use the threshold setting mode: PAUSE, press and hold PAUSE for 3 seconds, select the sensor, then feed at least 1.5 labels.

Likely cause

The B-EX6 finds the start of the labels with a gap sensor (transmissive) or a black mark sensor (reflective). According to Toshiba, a sensor that is mispositioned, unsuited to the media or not calibrated causes NO PAPER or PAPER JAM errors; setting the threshold corrects detection faults with pre-printed media.

Official threshold setting procedure

1. Position the sensor: gap sensor at the centre of the gap between labels, or black mark sensor at the centre of the black mark. To locate the mark, pull out about 500 mm of media, fold it back and pass it under the head again so that you can see the mark from above.
2. In online mode, press PAUSE, then hold PAUSE down for 3 seconds to enter threshold setting mode.
3. Select the sensor with UP or DOWN: “1) REFL.(PRE-PRINT)” (reflective) or “2) TRANS.(PRE-PRINT)” (transmissive), then confirm with ENTER.
4. Load the media and press PAUSE; hold PAUSE down to feed at least 1.5 labels, then release it.
5. Read the result: OK (Mid.) is optimal; OK (High) or OK (Low) works but fine adjustment is advised; NG requires an adjustment or a new attempt with FEED. Confirm with ENTER.
6. Depending on the sensor type defined in the print command, you may need to select MANUAL THRESHOLD (system mode, SENSOR > THRESHOLD SELECT), then switch the printer off and on again; then check the feed with FEED.

When to call a technician: if setting the threshold does not fix a NO PAPER or PAPER JAM error, Toshiba asks you to switch the printer off and call an authorised technician.

During threshold setting, paper end and ribbon end are not detected. The values are kept in memory: there is no need to repeat the procedure for the same media. The initial setup wizard also offers a CALIBRATE mode (OFF, LABEL/GAP, BLACK MARK), and automatic calibration is set in SET PARAMETERS > CALIBRATE in user system mode.

Short answer: In its initial state, the printer feeds according to its default settings: gap sensor, thermal transfer printing and a label pitch of 76.2 mm. If your media is different, set the print conditions in the driver or by command, then clear the error with RESTART.

Likely cause

According to the Toshiba manual, the feed was requested with the default settings (gap sensor, thermal transfer, 76.2 mm pitch), which do not match the media loaded.

What to do

1. Press RESTART to clear the error.
2. In the printer driver (Stock tab) or by command, set the print method, the sensor type, and the label size and gap to match your media.
3. Then feed one or two labels with FEED to set the print start position.

The initial setup wizard, launched at first start-up or after the parameters have been cleared, lets you choose printing with or without ribbon and the calibration mode (OFF, LABEL/GAP, BLACK MARK).

Short answer: According to Toshiba, the media is incorrectly loaded or the printer is in an error state. First deal with the message displayed, then reload the roll: media centred, guides adjusted to the width, straight path under the head and sensor positioned over the gap or black mark.

Likely cause

The manual lists two causes: media incorrectly loaded; printer in an error state.

Caution: Do not touch moving parts: load the media only once the printer mechanism has come to a complete stop (fingers, jewellery and clothing could be caught). Let the head cool down, do not touch its components and keep your fingers clear when closing the cover (Toshiba warnings).

Official media loading procedure

1. If an error message is displayed, deal with it first (see the lookup table).
2. Open the top cover, turn the head lever to FREE, release the holder plate and open the printhead block.
3. Turn the locking ring of the roll holder anticlockwise, remove the roll holder, then place the roll on the shaft.
4. Pass the media around the guide shaft and pull it towards the front of the printer.
5. Push the roll holder back against the roll, which centres itself automatically, then tighten the ring clockwise, without overtightening.
6. Place the media between the guides, adjust them to the width and tighten the locking screw; check that the media is straight and centred under the head.
7. Lower the printhead block, position the sensor over the gap or black mark, load the ribbon if needed, then lock the head lever and close the cover.

Do not turn the locking ring too far: it can come off the roll holder. Toshiba recommends storing rolls flat on their side, in their bag, away from dust, heat, humidity and sunlight.

Short answer: Toshiba asks you to remove all slack from the ribbon before printing, because a wrinkled ribbon degrades the print. Also check that the ribbon is centred by its stoppers, fitted with their clips facing the inside of the printer.

Likely cause

According to the manual, slack in the ribbon causes wrinkles that reduce print quality. The manual also asks you to centre the ribbon using the stoppers, fitted with their clips facing inwards.

What to do

1. Check that the ribbon stoppers are fitted with their clips facing the inside of the printer and that the ribbon is centred.
2. Wind the leader onto the take-up core until the ribbon appears at the front, to remove any slack.
3. Lock the head lever (Lock) and close the cover.
4. Choose a ribbon suited to the media type, and do not load a ribbon with direct thermal media.

On the B-EX6T1, ribbon save mode stops the ribbon feed over unprinted areas; it requires a minimum unprinted area of 20 mm at 3 and 5 ips, 25 mm at 8 ips, 35 mm at 10 ips and 60 mm at 12 ips.

Sources: 2.3.2 Loading the Ribbon (opens in a new window) · 5.2 Possible Problems (opens in a new window) – Toshiba B-EX6T Series Owner's Manual (official documentation).

Short answer: Toshiba cites an unsuitable ribbon / media combination and a dirty printhead. Clean the head with the printhead cleaner or a cotton swab lightly moistened with ethyl alcohol, and check that the ribbon is suitable for the media.

Likely cause

According to the manual: ribbon and media not matched; dirty printhead.

Caution: Unplug the power cord before any maintenance, let the head cool down, do not use volatile solvents (thinner, benzene), do not touch the head element with bare hands (static electricity) and never pour water onto the printer (Toshiba instructions).

Official cleaning procedure (printhead, platen, sensors)

1. Switch the printer off and unplug it.
2. Open the top cover, turn the head lever to FREE, release the holder plate and open the printhead block.
3. Remove the ribbon and the media.
4. Clean the head element with the printhead cleaner, or with a cotton swab or soft cloth lightly moistened with alcohol.
5. Wipe the platen, the feed roller and the pinch roller with a soft cloth lightly moistened with alcohol, and remove the dust inside the printer.
6. Wipe the gap sensor and the black mark sensor with a soft, dry cloth, then reload the media and the ribbon.
7. If the image is still blurred, choose a ribbon suited to the media type.

Toshiba recommends cleaning daily with heavy use, weekly with light use, and every time you change the media or ribbon. The printhead cleaner is available from authorised Toshiba Tec technicians. The covers and the panel are cleaned with a soft cloth, dry or lightly moistened with a mild detergent, never with alcohol.

Sources: 5.2 Possible Problems (opens in a new window) · 2.3.2 Loading the Ribbon (opens in a new window) – Toshiba B-EX6T Series Owner's Manual (official documentation).

Short answer: During a long continuous print run, the printer spaces out its printing to let the printhead cool down. The Toshiba user manual states that you can keep using it this way, with no effect on its service life or on safety.

Likely cause

According to the French user manual, the head temperature rises during a long continuous print run; the printer then reduces its printing rate to cool it down.

What to do

1. Let the printer carry on: according to Toshiba, this behaviour is normal.
2. If the printer stops with the message EXCESS HEAD TEMP, follow the head too hot entry.

Source: Troubleshooting (opens in a new window) – Toshiba B-EX6T Series French user manual (official documentation).

Short answer: A communication error has occurred (parity, overrun or framing error on the RS-232C serial link, according to the messages appendix). Check that the interface cable is properly connected to the printer and the computer and that the computer is switched on, then press RESTART.

Likely cause

The manual indicates a communication error; the messages appendix specifies a parity, overrun or framing error on the RS-232C link.

What to do

1. Check that the interface cable is correctly connected to the printer and to the host computer.
2. Check that the host computer is switched on.
3. Press RESTART to clear the error.

As standard, the B-EX6 has USB and local area network (LAN); the RS-232C serial interface, parallel and Wi-Fi are options. When LAN or Wi-Fi is active, the online screen shows the IP address and, on Wi-Fi, the signal level and the status of the connection to the access point.

Short answer: The printer has received an incorrect command in download mode, for example during a firmware update. The Toshiba manual asks you to switch the printer off and on again.

Likely cause

According to the manual, an incorrect command was received in download mode, for example during a firmware update. The key operation specification states that the second and third lines of the display show the bytes of the command concerned.

What to do

1. Switch the printer off and on again.
2. To update the firmware, Toshiba provides a download mode (boot and main programs) and an automatic configuration mode that updates the firmware from a USB memory stick.
3. If the error persists, switch the printer off and call an authorised technician.

The owner's manual does not detail the firmware update procedure.

Short answer: To get out of an error or a pause, hold CANCEL down for 3 seconds: the printer performs a quick reset and goes back online. Errors that RESTART does not clear require you to switch the printer off and on again; clearing the RAM (RAM CLEAR) is done in system mode.

Likely cause

The Toshiba key operation specification distinguishes resuming with RESTART, the quick reset with CANCEL and restarting, which is needed for errors that RESTART cannot clear.

Caution: Switch the printer off with its power switch, not by unplugging the cord. Do not switch it off during printing (risk of a jam or damage) or when the ONLINE light is flashing (risk to the connected computer).

Official procedures

1. Simple resume: press RESTART to resume after a pause or a recoverable error.
2. Quick reset: in an error or pause state, hold CANCEL down for 3 seconds; the data received is cleared as long as the button is held down. Release it only once all the data has been deleted, otherwise a command error may occur.
3. Restart: check that the display shows ON LINE and that the ONLINE light is solid, switch the printer off with its power switch, then switch it back on. The print data in memory is erased.
4. Return to the initial settings: after clearing the RAM (RAM CLEAR) in system mode, switch the printer off and on again; the initial setup wizard then asks for the language, printing with or without ribbon and the calibration mode.

According to Toshiba, system mode is mainly intended for maintenance staff. The quick reset sets the print counter to zero and clears the image memory; if automatic calibration is enabled, it then runs.

Short answer: RFID WRITE ERROR indicates that writing an RFID tag failed despite the set number of retries: press RESTART. RFID ERROR indicates that the printer is no longer communicating with the RFID module: switch it off and on again.

Likely cause

RFID WRITE ERROR: tag write failure after the set number of retries. RFID ERROR: no communication with the RFID module. RFID CONFIG ERROR: RFID module destination code not set (models with a pre-installed U2 or U4 module).

What to do

1. RFID WRITE ERROR: press RESTART.
2. RFID ERROR: switch the printer off and on again, as RESTART is not enough.
3. If the error persists, switch the printer off and call an authorised technician.

When to call a technician: if an RFID error persists after restarting, Toshiba asks you to switch the printer off and call an authorised technician.

The RFID module (B-EX706-RFID-U4-EU/US/AU-R) is only available as an option for the B-EX6T1; GS/TS12-CN-R models do not support it. According to the key operation specification, RFID calibration requires calibration to be carried out first (SET PARAMETERS > CALIBRATE), and only the FRONT antenna position can be used.

Short answer: An incorrect password has been entered three times in a row. Toshiba asks you to consult the system administrator; the printer must be switched off and on again.

Likely cause

INPUT PASSWORD: the printer is waiting for a password to be entered. PASSWORD INVALID: incorrect password entered three times in a row.

What to do

1. Switch the printer off and on again, as the Please Power OFF message indicates: RESTART does not clear this error.
2. Ask the printer's system administrator for the password.

This guide does not give out any password: contact your administrator or refer to the Toshiba documentation.

Short answer: Toshiba cites a disconnected power cord, a faulty mains socket, or a blown fuse or tripped circuit breaker. Plug the cord back in, test the socket with another appliance and check the fuse or circuit breaker.

Likely cause

Three causes in the manual: power cord disconnected; mains socket not working; blown fuse or tripped circuit breaker.

What to do

1. Plug in the power cord.
2. Check the socket by plugging in the cord of another electrical appliance.
3. Check the fuse or the circuit breaker.
4. Set the power switch to ON: on a normal start-up, the display shows ON LINE and the ON LINE and POWER lights come on. If another message is displayed or if the ERROR light comes on, see the lookup table.

When to call a technician: if the printer still does not start, Toshiba asks you not to attempt to repair it: unplug it and contact an authorised technician.
