Black ink from the black cartridge is not used).

Poor Print Quality or Missing Colors:

If any streaks or missing colors appear on prints, thoroughly clean the cartridge’s electrical contacts and printer’s flex driver cable surface. If the cartridge is clogged then a warm water flush may be necessary to recover all colors. Click here for instructions.

Partially Jetting Nozzles



NOTE 1: Replacing the ink cartridge is the best way to verify cartridge/printer performance.

NOTE 2: All cartridges being repeatedly refilled eventually do fail.  Some cartridges/printers may encounter an unavoidable mechanical or electrical failure which is unrelated to refilling.  Check for physical damage on the cartridge.  Look at the print cartridge and see if there are any cracks, tears or missing elements.  Any one of these can cause a failure.  In these cases, you will need to purchase a new cartridge and start the refill process again after it has run out.
