SOURCE: printer won't print
I've had this 6110xi all-in-one for a few years now. Everytime I have the "no-printing" issue I need to unplug the printer, and leave it unplugged overnight. The problem magically goes away in the morning.
I've installed the printer on a separate computer while it was having a "no-printing" episode and still couldn't print there either. So it sounds like there's something funky with the printer internal cache requiring a long power-down.

Had the same problem. Cleaned the copper-colored "contacts" on the actual printer. Where the printer and the cartridge touch ... you will see them when you take the cartridge out. Hope that helps.

Same problem with me.
I openede the whole box ( 4 screws ) in the corners. Then I presed the tiny belt on the left side to its socket, cleaned the contacts of the cartridges (56,57) with water and made them dry.
Then I reched the position of the small door which is ment to be opened once you wnat to replace the cartridge.
After this the printer works again.
