Epson ET-15000 Not Printing After Head Cleaning and Maintenance Box Replacement - Troubleshooting Guide

Question:
My Epson ET-15000 is not printing anything at all. I've already cleaned the printhead and replaced the maintenance box, but there's still no output. What else can I try?

Answer:
1. Confirm Whether It's a Printhead Issue or Ink Delivery Issue

Since you've already performed a printhead cleaning, the next step is to determine whether ink is actually reaching the printhead.

• Print a Nozzle Check Pattern from the printer menu.

  • If the page comes out completely blank, this usually indicates no ink is reaching the printhead at all.

  • If you see faint or broken lines, then the issue is more likely partial clogging.

A completely blank page typically points to a severe ink flow issue, not just a dirty printhead.

2. Check Ink Lines and Dampers (Air Lock or Ink Starvation)

The ET-15000 uses an EcoTank system, which relies on gravity and slight pressure differences to deliver ink.

Common issues:

• Air bubbles in the ink lines

• Ink not flowing from the tank to the printhead

• Dried ink blocking the dampers

What to check:

• Are the ink tanks visibly full?

• Do you see air gaps in the ink tubes (if visible)?

• Has the printer been unused for a long period?

If air is present, the system may need priming, which standard cleaning cycles may not fully accomplish.

3. Capping Station and Pump Assembly Problems

Even if you replaced the maintenance box, the capping station and pump system may still be the root cause.

These components are responsible for:

• Pulling ink through the printhead during cleaning

• Keeping the printhead sealed and moist

Possible problems:

• Clogged capping station

• Weak or failed pump

• Dried ink buildup preventing suction

If the pump isn't pulling ink, cleaning cycles won't work-even if you run them repeatedly.

4. Electrical or Printhead Failure

If there is absolutely no ink output and no improvement after multiple cleaning attempts, consider:

• Burned-out printhead channels

• Loose or damaged printhead cables

• Mainboard issues

While the ET-15000 doesn't always show error codes for printhead failure, symptoms can include:

• Completely blank pages

• No response to cleaning cycles

• No improvement after ink system checks

5. Waste Ink System and Counter Reset (Maintenance Box Related)

You mentioned replacing the maintenance box, which is good. However:

• Some printers still require a waste ink counter reset

• If not reset, the printer may limit cleaning effectiveness

While this usually triggers warnings rather than blank prints, it's still worth confirming.

6. Firmware or Software Glitch

Occasionally, the issue may be software-related:

• Try printing from a different device

• Reinstall printer drivers

• Perform a power reset:

  • Turn off the printer

  • Unplug it for 5-10 minutes

  • Plug back in and retry

7. Advanced Cleaning (Manual Intervention)

If standard cleaning doesn't work, more advanced steps may be needed:

• Manual printhead flushing

• Cleaning the capping station manually

• Using cleaning solution through the ink intake

These require disassembly and should be done carefully to avoid damage.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems.
