A:AnswerIf you don't have directions, just open copier and pay attention to ink cartridge. There is a "handle" you flip up and the cartridge can be removed. Pay attention how you removed it to replace it with new cartridge. If all else fails, call Best Buy and they will gladly help you.
A:AnswerYes the OfficeJet 5255 uses HP 63 or HP 63XL ink cartridges. The ink came out before the printer did so the graphics on the ink box have not been updated yet.
