pattern, then the tri-color ink cartridge is either empty, clogged or severely electrically damaged (black
ink cartridge is not used). You can remove the tri-color cartridge, reactivate the tap 41 test and the
printer will print the diagnostic test print in black ink.
NOTE: To our team's knowledge there is no 'cartridge error bypass' method available for the HP Deskjet
D4200/D4300 printer model series.
*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. Blinking ink lamp indicators (or
Window's ink error messages) are 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.
Running the 'Tap 41' cartridge health diagnostics test will confirm the active state of both cartridges.
Please note these types of failures are quite rare with an ink cartridge that that has only been refilled
once or twice. For reference, the following page provides a complete review of the majority of cartri dge
error messages you may observe on your printer at one point or another:

However, if your printer works routinely after inserting a brand new HP 74XL cartridge in it, you should
discuss the possibility of a refund with your local Costco (for the refilled cartridge purchase). We regret
your inconvenience, and we hope that you will continue to consider the compelling value of inkjet
refilling in the future.
If you do decide to run the 'Tap 41' cartridge health diagnostics test mentioned above and have any
questions about the printed test report, please relay the results to our team for failure confirmation
(you should observe exactly 600 & 672 nozzles in the test report). For additional printer diagnostics
information please visit: http://inkjet411.com/?page_id=1813
Please let us know if you have any additional questions regarding procedures outlined above and/or
questions relating to the provided technical information. Before refilling your next each cartridge please
refer to the following video and proper handling and care of integrated ink cartridges:

ERROR MESSAGES - NOT RECOGNIZING CARTRIDGE (901)
Regarding your recent inquiry about the HP 901 black ink cartridge error condition (“Black Cartridge
Error”, or similar printer alert error language*) and inability to print with your HP OJ J4580 printer, this
type of error condition is likely an internal micro-electronic failure inside the HP 901 black ink cartridge.
An electronic failure of the cartridge would be unrelated to the ink cartridge refill process; these same
failures can (and frequently do) occur with brand new ink cartridges.**
