Fairly common it you refilled a lexmark cartridge. Try the usual print head alignment and cleaning and installng a new cartridge usually works. Also could be dried ink, air bubble in cartridge or cartridge became dried out before filling
I've got a Lexmark X83 all in one. The printer is having problems printing black. The text has turned to lines and broken letters. It frequently does not print at all but feeds the paper through at the same rate as if printing. Its a bit like the ink is not reaching the page at all. Any ideas how to cure this?
