Ink Cartridge Refill Help Center

HP Officejet J5700 & J6400 Printers

NOTE: “Empty” and “Low Ink” alerts are COMPLETELY NORMAL for all HP 74 and HP 75 ink cartridges which have been refilled!  While at first this may be an unusual workflow, it does allow print operations to proceed.

Many of the HP 74/75 ink cartridge alert and error messages you may encounter using refilled ink cartridges can typically be overcome using the steps provided below.  However, in some cases a marginally performing cartridge might be considered faulty by the printer. In this event, printer error bypass and HP diagnostic test procedures have been provided to help you correct and/or diagnose the cause of failure.

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.

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.
