So I installed a lexmark printer and when I send something to be printed, the printer starts, does what it should (?) which to me is printing, and then a blank page comes out. There is nothing at all on it, not even a dirty mark! When I try to print a test page it tells me it is printnig, paper feeds through, I can hear printing and then a blank page again. What is the problem. Yes, there is ink in the cartridge, because I get it on my fingers when I check the cartridge, so I need help please.
