Why Is My Epson Printer Not Printing Cyan Even After Multiple Cleanings and Maintenance Box Replacements?

Customer Question:

Epson Printer Not Printing Cyan Ink. Burst raw: I have already replaced more than 10 maintenance boxes, and many cleaning cycles have been performed. Not sure if it is the motherboard issue, do I send the motherboard for repairs?

Answer:

If your Epson printer has ceased to print cyan ink — even after you’ve emptied more than ten maintenance boxes and run several cleaning cycles — the motherboard is not the culprit. Instead, the problem almost certainly is with the printhead — a clog or a failure in the cyan channel.

Motherboards in Epson printers hardly ever fail with only one color channel getting dropped. If your printer's motherboard was faulty, then you'd expect more widespread issues like the printer not turning on at all, or errors in the form of an unreadable code: 0x97, 0x9A or complete full communication errors between the printer and the computer. As your printer is still trying to print and only one color, cyan is out, we can narrow our scope that the issue does not stem from the Mother Board.

Here’s what’s probably happening:

Clogged or Dead Cyan Nozzle:

Also, however, as all you people who have worked with Epson printheads, particularly the piezoelectric ones found in their EcoTank and WorkForce models, will know, the things can get clogged very quickly if unused or allowed access to air. Running the cleaning cycles helps to a degree, but excessive cleanings (particularly if more than 10 maintenance boxes have been consumed) indicate that the clog is serious or that the channel has reached a point of no return.

Air Paper Damage or Line Blockages Caused by Ink Starvation:

In some cases, trapped air or dried ink in the cyan supply lines may lead to no cyan output. But if you’ve performed that many cleanings, then this should have already washed out—making a clogged printhead more likely.

Channel Burnout:

In extreme cases, so many cleaning cycles can cause the printhead’s internal circuitry to overheat or degrade, leaving that particular color channel irreparably damaged. When that happens, no amount of cleaning or changing out your maintenance box will get that color back.

Sadly, this means the best-case solution is a complete printhead replacement. If you’ve already done dozens of cleanings and don’t see any improvement, further cleanings won’t resolve the problem and will only wear out more components.

Printer trouble is one of those things that can be a little tricky to deal with, given that printer issues can be hands on.
