can you try printing to it from a normal program like ms word

they may have just got stuck in there for some reason

like the last pages of the last thing you were trying to print before the ink ran out

go to the devices and printers folder and click on what is printing for the printer

cancel any jobs in there and then try to print something from a normal program a document or a picture.
