Customer Question

I have an EPSON WP-4540 printer and it keeps giving me warning that the black ink cartridge is installed incorrectly. I have repeatedly installed and reinstalled it and it clicks into place... I have turned it on and off... What else shall I try?

Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.

Sorry to hear you’re having trouble.

There are a few possible causes of this issue, including a bad cartridge, internal debris/contamination, or a hardware failure (bad printhead, bad logic board, faulty sensor, etc).

What we can try are some cleaning and reset steps.

First remove all of the ink cartridges, then clean the metal electrical contacts on the back, as well as where they mate up inside the printer, using qtips and rubbing alcohol. Dry well, then reseat the cartridges.

Then reset the machine:
unplug power at the wall outlet
wait 5 minutes
press and hold the power/on button for 60+ seconds
keep holding while plugging back in, and for another 60 seconds after, then release

Let me know the results, and I'll advise further if needed.

I did all of this and still the same warning sign came on
Expert:  Nathan replied 1 year ago.

Are you using genuine/oem epson ink, or generic/refilled cartridges?

Do you happen to have the old cartridge, or another new one, that you can test?

Should I try anything else?

I’ve attempted to accept your call request, but it appears to have failed on your end due to a payment issue. You may need to increase your deposit or clear a security hold on your account. I’ll resend a new phone offer from my end that may be more readily processed.

No, just checking a new cartridge, for now. What happened?
