Toshiba B-SA4TM III error paper-jam: Clearing Guide

The Toshiba B-SA4TM III error paper-jam stops the printing process due to a perceived or actual obstruction of labels in the printer's feed path. This error requires immediate attention to prevent label misalignment and print head damage. Following a few simple cleaning steps usually resolves the issue. This robust printer model performs best when the feed sensors remain free of debris.

Common causes

  • 1Sensor Obstruction: Sticky residue from labels blocking the light sensor.
  • 2Misalignment: Labels are shifted, causing a detection failure.
  • 3Driver Mismatch: Print length setting doesn't match the label size.
  • 4Sensor Aging: Optical components becoming less sensitive over time.

Solutions

Quick Diagnosis

If the status light blinks orange, inspect the sensor region. A paper jam notification often means the gap between labels is not being detected properly.

Step-by-step solution

  1. Open the thermal head release lever.
  2. Extract the label stock carefully.
  3. Clean the gap sensor using a cotton swab and isopropyl alcohol.
  4. Ensure the media guide matches the width of your labels.
  5. Close the mechanism and press the 'Feed' button.

Prevention and Maintenance

Use high-quality thermal label rolls. Adhesive residue can build up on the sensors over time; regular cleaning prevents repeated jam errors.

When to call a technician

If the machine fails to detect the gap even after sensor cleaning, the sensor assembly may be physically misaligned or damaged.
