had a recent paper jam, got cleared. worked fine though slightly noiser. replaced 2 ink cartriges, printing misaligned. got error c000. tried auto head align got partway through printing got code 5100. found strip of paper by gears on left side of printer - removed. Still can't print full alignment page.will print full page (in Color) from other programs. takes a long time "preparing to print" alignment page stalls with code 5100. other program has code 5100 after printing stops. any suggestions?
