Fujitsu DPK7000 E-05 Error: Paper Sensor Issues

The Fujitsu DPK7000 E-05 error occurs when the device detects no paper or a fault in the form detection sensor. This is common in environments where paper dust accumulates in optical sensor slots. The primary solution involves a deep cleaning of the paper input guides.

Common causes

  • 1Accumulation of paper dust in the optical presence sensor.
  • 2Misalignment of the paper tractor feed mechanism.
  • 3Degradation of the emitter diode in the paper sensor due to heavy usage.
  • 4Obstruction by external objects (staples, clips) in the feed path.

Solutions

Diagnóstico rápido

The error appears as soon as you attempt to start a print job or power up the unit. If paper is loaded but not recognized, we are dealing with a direct fault in the presence sensor. My Fujitsu DPK7000 shows E-05 error even with paper? Check that the paper properly blocks the input photocell.

Solución paso a paso

  1. Remove loaded paper from the tray or tractor.
  2. Use a can of compressed air to clean the paper sensor slot.
  3. Ensure no label fragments are stuck to the feed roller.
  4. Reinstall the paper, ensuring it is perfectly aligned.
  5. Restart the printer by holding down the 'Reset' button if supported.

Prevención y mantenimiento

Clean the feed rollers with a cloth dampened in isopropyl alcohol every 3 months to prevent paper slippage. Avoid forcing paper if the tractor feed is locked.

Cuándo llamar a un técnico

If the sensor fails to detect paper after a thorough cleaning, the sensor board likely requires replacement due to emitter diode degradation.

Frequently asked questions

This message indicates that the printer does not detect loaded paper or that the sensor is blocked by debris.

It is critical if your workflow depends on continuous forms; without the sensor, the printer cannot start the cycle.

The DPK7000 supports continuous fanfold paper with tractor feed.

Use compressed air or a swab with high-purity isopropyl alcohol in the sensor slot.
