Epson XP-15000 False Paper Jam Error During Startup After Printhead Cleaning

Question:
I have an Epson XP-15000. I was running a printhead cleaning, and suddenly the printer reported a paper jam. After resetting the printer, during startup the printhead only moves slightly to the right, then a little back to the left, and immediately shows a paper jam error again. What could be causing this?

Answer:
What you're experiencing is actually a fairly common issue with Epson printers like the XP-15000, and in many cases, it's not a true paper jam-even though the printer reports it as one.

Why This Happens

During startup, the printer performs an initialization sequence where the printhead (carriage) moves across the rail to confirm its position. If anything interferes with this process, the printer may trigger a false paper jam error (often displayed as a generic "paper jam" message without a specific numeric code).

Based on your description-where the printhead only nudges slightly right, then back left, and immediately errors-this strongly suggests that the printer cannot complete its initialization cycle.

Most Likely Causes and Fixes

1. Obstruction in the Carriage Path

Even a tiny piece of torn paper or debris can block the carriage.

What to do:

• Turn off and unplug the printer.

• Open the top cover.

• Carefully inspect the entire carriage path (left to right).

• Look for small scraps of paper, labels, or foreign objects.

2. Capping/Parking Station Jam (Very Common After Cleaning)

Since this happened right after a printhead cleaning, this is one of the most likely causes.

The capping station (on the far right side) is where the printhead parks and gets cleaned. Over time, it can accumulate dried ink or become stuck.

Symptoms:

• Carriage feels tight or blocked near the right side

• Printer stops immediately during startup

What to do:

• Gently slide the carriage (only if it moves freely-never force it).

• Inspect the right-side parking area.

• Look for:

  • Thick ink buildup

  • Sticky or hardened residue

  • Misaligned components

3. Dirty or Misaligned Encoder Strip

The encoder strip is a thin, transparent plastic strip behind the carriage that tells the printer where the printhead is.

If it gets dirty (ink smears, grease, dust), the printer may lose track of position and trigger a jam error.

What to do:

• Locate the clear strip behind the carriage.

• Check for:

  • Ink smudges

  • Fingerprints

  • Dust buildup

• If dirty, gently clean it using a lint-free cloth and a small amount of water or isopropyl alcohol.

4. Sensor Lever or Flag Stuck

Printers use small plastic flags/sensors to detect paper movement. If one gets stuck, the printer may falsely think paper is jammed.

What to check:

• Rear paper feed slot

• Internal paper path

• Paper cassette area

Even a slightly misaligned sensor can trigger a jam error.

5. Service Unit / Pump Mechanism Issue

If you notice:

• Grinding noises

• Clicking sounds

• Carriage completely stuck on the right side

Then the issue may be with the service station (pump assembly) rather than paper.

This is more mechanical and may require disassembly or part replacement.

Recommended Troubleshooting Order

1. Power off and unplug the printer

2. Inspect for paper debris everywhere (especially under carriage)

3. Check carriage movement (only if it moves freely)

4. Inspect and clean the encoder strip

5. Examine the right-side capping/parking station

6. Recheck rear feed and cassette areas

7. Power back on and test

Addressing printer issues can be tricky because they often involve hands-on mechanical inspection. Unfortunately, we're not able to provide remote troubleshooting or step-by-step repair guidance beyond general advice. However, we do offer an in-person evaluation and repair service through our local diagnostic facility (https://bchtechnologies.com/printer-repair-service). Given the high demand, we operate on a first-come, first-served basis, so it may take a few weeks before we can accept your printer.

Our services cover both full printer repairs and individual component fixes, with clear instructions provided. That said, we understand our rates may not be the most budget-friendly option, so we strongly encourage exploring self-help resources first. A great place to start is YouTube-especially our channel homepage (https://youtube.com/@bchtechnologies). You can use the search icon next to the "About" tab to quickly find videos on specific issues. With hundreds of videos created over the past nine years, this is the fastest way to locate relevant content. You may also discover helpful videos from other creators that address your specific problem.

Thanks again for reaching out and for your continued support. We truly appreciate it, and we hope this helps you get your XP-15000 back up and running!
