The quickest way to determine whether an image defect is cartridge or printer related is to replace the cartridge.

  • If you have two of the same model printer you can swap the cartridges around.
  • If the problem follows the cartridge then you know it is a cartridge problem.
  • If the problem stays with the printer, despite what cartridge is fitted, then it’s a printer problem(Pls Refer to our Installation Guide).
