Hi there. Do you use the printer often? I discovered from another forum that if you don't use it very often the inks dry out even though your printer thinks they're full (especially if they're compatibles). Have a check and see if this is the case. If so change them over, switch the printer off and as soon as it comes on get it to do a print head clean. You might have to switch on and off a couple of time and do a couple of cleans. It's a pain and requires patience but it's worked for me a couple of times now. Good luck!
