Solving Paper Jam Errors on the Epson 8550: Causes & Fixes

Question:
I had my Epson 8550 repaired for clogged white DTF ink, but now I see a paper jam error—though no paper is stuck. I even recorded a video showing the process. What’s causing this?
 
Answer:
Paper jam errors without an actual jam can be tricky, but they often point to sensors, rollers, or media issues. Here’s a step-by-step guide to diagnose and resolve the problem:
 

1. Paper Ejection Sensor

The ejection sensor checks if the paper exits correctly. Misalignment or debris can cause a false jam error.

• Solution: Clean the sensor with compressed air, a lint-free cloth, and isopropyl alcohol.

2. Page Feed Sensor

This sensor monitors paper movement. Obstructions or wear could cause misreads.

• Solution: Inspect for blockages or damage. Replace the sensor if necessary.

3. Roller Alignment

Misaligned or dirty rollers can skew paper feeding, confusing the printer.

• Solution: Clean the rollers with a damp, lint-free cloth. Could you check alignment and look for wear?

4. Film or Media Issues

Even minor misalignments or incompatible media can trigger errors.

• Solution: Ensure the film thickness matches the printer specs. Load media flat and square.

5. Firmware or Software Glitches

Sometimes, software bugs cause phantom errors.

• Solution: Update your printer’s firmware from the Epson website. If needed, reset the printer to factory settings.

6. Internal Hardware Faults

The issue may involve internal printer mechanisms if none of the above fixes work.

• Solution: Seek professional diagnostics and repair.
