How to Fix Epson ET-15000 Not Printing After Sitting Idle: Cleaning, Clogs, and Ink Flow Issues

Question:
I have an Epson ET-15000 printer that hasn't been used for a while, and now it won't print properly. I want to clean the ink system and get it working again. Do you have a video that shows how to do this?

Answer:
Based on your description, I assume you're referring to the Epson EcoTank ET-15000. When a printer sits unused for an extended period, the most common issue is printhead clogging, but there are a few possible causes to consider.

1. Printhead Clogs (Most Common Issue)

When ink sits idle, it can dry inside the printhead nozzles, especially with pigment inks. This results in:

• Missing colors

• Faded prints

• Completely blank pages

What to do:

• Run a Nozzle Check from your printer's maintenance menu.

• Identify which colors are missing or broken.

• Perform printhead cleaning cycles (start with 1-2 cycles, then wait 10-15 minutes before repeating).

⚠️ Avoid running too many cleanings back-to-back, as this can overfill the waste ink pad and potentially trigger errors like:

• Error 5B00 / Waste Ink Pad Full (common in Epson models)

2. Air in the Dampers (Ink Supply Issue)

If the printer hasn't been used in a long time, air may have entered the dampers (the small ink reservoirs above the printhead). This can prevent ink from reaching the printhead, even if the nozzles are not clogged.

Symptoms:

• No ink output at all for certain colors

• Cleaning cycles don't improve anything

Solutions:

• Perform a Power Cleaning / Ink Charging / Ink Fill (if your printer supports it). This forces ink through the system.

• If that doesn't work, a more advanced method is:

  • Remove the dampers

  • Manually draw ink into them using a syringe
    (This requires caution and some technical skill.)

3. Weak Cleaning Cycles

Standard cleaning cycles may not be strong enough if:

• The printer has been idle for months

• Ink has dried deeper in the system

In this case, using the Ink Charging / Initial Ink Fill function is more effective. However:

• This consumes a significant amount of ink

• It should only be used when necessary

4. Related Video Guide

Yes, we do have a video that may help guide you through the process:

This video provides a visual walkthrough of cleaning approaches and can help you better understand the steps involved.

5. Additional Tips

• Always start with the least invasive method (nozzle check → cleaning → deeper cleaning).

• If only one color is affected, focus your efforts there.

• If all colors are missing, it's more likely an ink delivery issue (air or blockage upstream) rather than just a clog.

Addressing printer issues can sometimes become complex due to the hands-on nature of the repairs involved. Unfortunately, we're not able to provide remote troubleshooting or step-by-step repair support. However, we do offer an in-person evaluation and repair service through our local diagnostic facility: Printer Repair Service (https://bchtechnologies.com/printer-repair-service). Please note that due to high demand, we operate on a first-come, first-served basis, and it may take a few weeks to schedule a drop-off.

Our services cover both full printer repairs and specific component fixes, with clear guidance provided throughout. That said, we understand our services may not be the most budget-friendly option. Therefore, we strongly recommend exploring self-help resources first. A great starting point is YouTube-especially our channel homepage: BCH Technologies YouTube Channel (https://youtube.com/@bchtechnologies).
