Toshiba e-STUDIO 856SE error E050: Solutions
The Toshiba e-STUDIO 856SE error E050 is a service alert indicating a malfunction in the device's paper exit sensor (or finisher unit). This error happens when the sensor detects that a sheet did not reach its final destination on time, suggesting a hidden jam or a sensor contaminated by toner or paper dust.
Common causes
- 1Exit sensor flag stuck due to paper dust.
- 2Dirty optical exit sensor.
- 3Remnants of labels or adhesives stuck in the paper path.
- 4Electronic failure in the final exit sensor.
Solutions
Quick Diagnosis
The error appears frequently when the 'flag' (the small plastic lever that activates the sensor) gets stuck due to dust. If nothing is visible at the paper exit, the sensor is likely dirty or the flag is broken.Step-by-step Solution
- Open the output door and remove any visible paper.
- Use compressed air to blow over the exit sensors to clean off paper dust.
- Gently move the plastic sensor flag with your finger to verify it returns to its original position.
- Reboot the unit; if the flag returns to the correct position, the machine will recognize the path as clear.
Prevention and Maintenance
Paper dust buildup is inevitable in 85 ppm equipment. Clean the entire exit area with compressed air at least once a month. Avoid using industrial staples that could damage the sensor lever upon exiting.When to call a technician
If cleaning the area and verifying the flag does not resolve the E050 error, the optical sensor may be faulty and requires complete replacement by a technician.Technical Data
