Fixing Epson WF-7620 Error Code 0xE5: Causes and Solutions

Question:

My Epson WF-7620 printer is showing error code 0xE5. I was in the middle of my homework and have no idea what to do. Can you help?

Answer:

Epson WF-7620 Error code 0xE5 means Carriage Return (CR) PID Speed Failure This happens when the printer powers the carriage return motor but doesn’t get the expected response from the CR encoder. So here are the reasons for this error most commonly encountered:

CR Encoder Failure: The CR encoder tracks the position of the printhead. The encoder strip can be crippled by dust or ink accumulation on it.

Motor Driver or Mainboard Failure: These components are responsible for driving the carriage motion, and any failure may result in triggering the error.

Timing Belt Problems: A loose or misaligned timing belt could lead the carriage to move incorrectly or skip teeth.

Paper Jam: Stuck small paper piece blocking carriage movement.

So, to troubleshoot, start by cleaning the CR encoder strip. The strip is a film-like, transparent ribbon that is installed next to the timing belt. Gently wipe both sides with a lint-free cloth moistened with isopropyl alcohol. Make sure that strip has been correctly slotted into position.

If cleaning the encoder does not solve the problem, look at the timing belt to ensure it has the right tension and is aligned correctly. A loose or worn or misaligned belt may require adjustment or replacement. Finally, examine the carriage path for obstructions, such as paper scraps or debris, that could cause it to stall.

If the error still appears, the cause might be a broken motor driver or mainboard. These are tricky components to repair and often require professional service.
