Epson SureColor P400 Error 0x34: Carriage Fix

The Epson SureColor P400 error 0x34 indicates that the print head carriage has encountered an obstacle or lost its position reading. This error often arises due to dirt on the encoder strip, which is responsible for telling the software exactly where the print head is located. Solving this failure is crucial to protecting the motion motors' lifespan.

Solutions

Quick Diagnosis

If the 0x34 error appears at startup or just before a print job, it is likely that a physical obstruction, such as paper remnants or hardened grease on the rail, is preventing movement.

Step-by-Step Solution

  1. Turn off the printer and unplug the power cable.
  2. Open the main lid to access the carriage area.
  3. Carefully inspect the transparent strip (encoder) spanning the device interior; if ink or dust is present, clean it with a lint-free cloth.
  4. Gently slide the print carriage from side to side to ensure no mechanical blocks exist.

Prevention and Maintenance

Keep the environment dust-free. We recommend cleaning the metal rail with printer-specific oil once a year and ensuring print heads don't strike thick media.

When to Call a Technician

If after cleaning the encoder and checking the rail the carriage still hits the side walls, the motor or timing belt may have failed.
