My printer reads cover open however the cover is closed. this error message occurred after the ink was changed. What am I missing?

My Epson Artisan 810 repeatedly would give me the printer error message with the only option to turn off the unit and turn it on again. Over and over it would give me the printer error message. With the unit off, I opened the cover (like you would to replace the ink cartridges) and forced the CD tray all the way out like you are about to load a CD for printing, closed the cover, then started the unit up again. For me that did the trick. It went through it's normal 60 seconds or so of set-up, then worked fine ever since. Not sure if this will work for you, but it worked for me.

Hello!
Remove the cartridges and gently wipe the cartridge contacts with a dry cloth, then put them back in. Then, hold the "resume" button for 10 seconds for each cartridge, that should reset them.
If that doesn't work, one of your cartridges (sadly) needs to be replaced.

Try reseating the ink cartridge and see if the cover door is firmly closed.

I had that problem too.

Unplug the printer.
Hold the printer cover open while you plug in the printer.
Then wait for the printer to power on while still holding the cover open.
Then close the cover.
The buttons should work and th error message should be gone.

It worked for me.
