Solving Paper Jam Errors on an Epson 8550: Common Causes and Fixes

Question:
I previously had my Epson 8550 repaired for clogged white DTF ink, but I’m now experiencing a different issue. My printer displays a paper jam error even though there isn’t a jam. I’ve taken a video to show what happens during the process. What might be causing this problem?

Diagnosing the Paper Jam Error

The printer can load the film successfully based on the information provided and after reviewing the details in your video. Since you’ve also taped the back of the film, this likely rules out the PW (Paper Width) sensor as the cause. Here’s a step-by-step breakdown of what might be causing this false paper jam error and how to address it:

1. Paper Ejection Sensor

  • The paper ejection sensor detects whether the paper is exiting the printer correctly. If it’s misaligned, dirty, or malfunctioning, it might falsely report a jam.
  • Solution: Inspect the ejection sensor for debris, dust, or ink buildup. Clean it gently using compressed air or a lint-free cloth with isopropyl alcohol.

2. Page Feed Sensor

  • The page feed sensor monitors the paper’s movement through the printer. A misreading could trigger a jam error, especially if the sensor is blocked or faulty.
  • Solution: Check the feed sensor and surrounding mechanisms for obstructions or wear. If necessary, replace the sensor.

3. Roller Alignment

  • Misaligned or worn rollers may cause the paper to skew during feeding, confusing the printer into thinking there’s a jam.
  • Solution: Inspect the rollers for wear or improper alignment. Clean them using a damp, lint-free cloth to remove dirt or ink residue.

4. Film or Media Issues

  • Although you’ve taped the back of the film, ensure the media is within the specifications for your printer and loaded correctly. Even slight misalignments can cause feeding problems.
  • Solution: Double-check the film’s thickness and ensure it’s placed flat and square in the tray.

5. Software or Firmware Glitch

  • Occasionally, a software or firmware bug can cause phantom errors like paper jams.
  • Solution: Remove and re-install the RIP software. Believe or not, I've heard it solved the fake jam problems for my customers.

6. Internal Hardware Issues

  • If the issue persists after checking the above, there might be a fault with the printer’s internal mechanisms.
  • Solution: At this stage, a professional diagnostic evaluation may be necessary to identify and repair internal hardware issues.
