The Epson WorkForce Enterprise WF-C17590 error W-04 indicates a communication error between the main unit and the paper feeding tray. This usually occurs if the tray is not correctly seated or if dust prevents the sensor from confirming the tray status. This is a common maintenance issue in high-volume enterprise printing environments.

Common causes

  • 1Misalignment: Tray not fully locked into the bay.
  • 2Obstruction: Debris covering the optical tray sensor.
  • 3Mechanical Wear: Excessive slack in the tray rail system.
  • 4Sensor Failure: Malfunction of the tray lock electrical switch.

Solutions

Quick Diagnosis

Check the front panel message; if it says 'Tray Not Detected', look for debris in the tray slot. Verify the tray is pushed all the way in.

Step-by-Step Solution

  1. Pull the affected paper tray out of the printer housing completely.
  2. Inspect the compartment and the rear side of the tray for any paper remnants.
  3. Wipe the optical sensor area with a dry cloth to clear any obstructing dust.
  4. Reinsert the tray, listening for a solid click confirming the connection.

Prevention and Maintenance

Do not force the tray into place. Clean the paper pickup rollers once a month to ensure smooth feeding and sensor health. Using genuine Epson ink helps keep internal components cleaner for longer.

When to Call a Technician

If the error persists after checking the tray position and cleaning sensors, a hardware fault in the connector board is likely. Contact a technician for component replacement.
