Common causes

  • 1Broken or exhausted ribbon.
  • 2Obstruction of the ribbon motion sensor.
  • 3Tension spring failure in the supply spool.
  • 4Build-up of adhesive or ribbon fragments inside the path.

Solutions

Quick Diagnosis

The error manifests as an immediate stop on the LCD display. Inspect the ribbon supply; if it appears normal, the ribbon path sensor is likely obstructed. Ensure the take-up spindle is rotating smoothly and not stalled by residue.

Step-by-Step Solution

  1. Release the print head using the side lever.
  2. Check for ribbon breakage and verify it is correctly routed through the guides.
  3. Tighten the ribbon manually on the collection spool to remove slack.
  4. Clean the ribbon sensors with canned air or a dry cloth.
  5. Lower the print head and press the reset button on the interface.

Prevention and Maintenance

Regularly clean the platen roller and print head. Maintain proper tension settings based on the ribbon width. Using authentic Toshiba-certified media helps maintain the calibration of the sensor path.

When to Call a Technician

If the reset fails and the error recurs, there may be an electronic fault in the motor board or a damaged ribbon encoder. Do not attempt internal repairs, as industrial components are sensitive.
