indicates a problem with the black or photo cartridge. Faded, streaked or missing lines in the other colors indicates a problem
with the color i nk cartridge.
To determine which cartridge is causing the problem:
1. Open the cartridge access door.
2. Remove either cartridge (not both).
3. Close the cartridge access door.
-- If the computer message is Print Cartridge Error , then the print cartridge that is still in
the printer is the problem cartridge. If the computer message is NOT Print Cartridge
Error (instead, it says that the cartridge you have removed is ...Either missing, not
detected, or incorrectly installed), then the cartridge you have removed is the problem
cartridge.
--- Providing the color cartridge is partially functioning, the diagnostic test print will be printed (this is a
forced service print test which is mainly used for the evaluation of ink cartridge electrical health). A good
HP 21/27/56 black cartridge should display 416 good nozzles (26x16 grid), while a good HP 22/28/57/58
color ink cartridge should show 300 good nozzles (10x10 color grid). For reference, please refer to video
at link below to help evaluate test pattern. [NOTE: HP 56/57/58 and HP21/22 cartridges are electrically
similar]: http://inkjet411.com/?page_id=2358
*Many cartridges eventually do encounter problems or failures, especially after their original ink is gone
and they are re-used, and this is often unrelated to the refill process. The “Wrong Cartridge
Type/Installed" / “Print cartridge is not compatible with this device” / “Cartridge Error” / “Print
Cartridge Error” / ‘blinking lights” alert/error message is typically indicative of failed micro-electronics
internal to the ink cartridge(s). Also note that it is common to have a marginally performing ink cartridge
(which was performing ok before) in the adjacent slot (i.e. color), then when a marginally performing
cartridge is installed into the other slot (i.e. black), both of the ink cartridge(s) then get flagged with
electrical errors.
Please note this type of failure is quite rare with an ink cartridge that that has only been refilled once or
twice. Severe cartridge errors are primarily caused by an electrical breakdown at the cartridge’s nozzle
plate. Ink penetration or corrosion into the nozzle plate will cause a failure of the tiny micro -electronics
resulting in a variety of different error messages being displayed – see bottom image at this page:

However, if your printer works routinely after inserting a brand new cartridge in it, you should discuss
the possibility of a refund with your local Costco (for the refill purchase). We regret your inconvenience,
and we hope that you will continue to consider the compelling value of inkjet refilling in the future.
