Toshiba TEC B-573 error E-301: Ribbon failure guide
The Toshiba TEC B-573 error E-301 indicates a system failure regarding the thermal transfer ribbon. This often occurs when the motor doesn't detect ribbon advancement or the sensor is covered. Users asking why does my Toshiba TEC B-573 show error E-301 usually need a ribbon and sensor check.
Common causes
- 1Thermal ribbon is empty or snapped.
- 2Carbon buildup on the detection sensor.
- 3Incorrect tension in the drive spindles.
- 4Mechanical ribbon motor lockout.
Solutions
Quick Diagnosis
If the error appears, check if the ribbon is present, intact, or if the sensor is obstructed by carbon buildup.Step-by-step Solution
- Open the cover and ensure the ribbon is tight on both cores.
- Verify the thermal side faces the printhead correctly.
- Clean the ribbon sensor with compressed air or a soft swab.
- Restart the unit to reinitialize the sensor check.
Prevention and Maintenance
Carbon dust is a common nuisance for sensors. Maintain a cleaning schedule in production areas to ensure ribbon movement remains detectable.When to Call a Technician
