However, if your printer works routinely after inserting a brand new HP74/74XL and/or HP75/75XL ink
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 cons ider the
compelling value of inkjet refilling in the future.

HP OJ J5700-J6400 ERROR MESSAGES - NOT RECOGNIZING CARTRIDGE (74-75)
NOTE: For purposes of our communication please note that the HP 350/351 UK cartridges are the same
as the HP 74/75 USA versions; all the features and functions discussed below will work on your printer as
the printer platforms are identical.
Regarding your recent inquiry about the HP 75XL cartridge error message (“xxx”) and inability to print
with your HP OJ J5700 printer, this type of error is normally associated to an electrical connection issue
between the printer and the cartridge, or more likely, an internal micro-electronic failure inside the
cartridge itself. 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.* To help
identify the root cause, and to confirm/determine which of the two ink cartridges is causing the failure
condition, please run the 'Tap 41' cartridge's electrical diagnostic test below (refer to C.)
Please first verify the age of the ink cartridge(s)....look at imprinted date on front of ink cartridge. If this
‘warranty expiration date’ has expired, then potential internal electrical cartridge failures can occur due
to internal corrosion, etc.
NOTE: Unfortunately, alignment pages and internal self test prints will usually print Ok even if the
cartridge is internally electrically damaged. Do not use these test pages as a proxy for determining
whether a cartridge is good or bad, only the ‘Tap 41/43’ diagnostic test report can yield this information.
An internal electrical failure of a cartridge can be confirmed by performing the following steps which will
help rule out other variables which could also be causing the issue.
A. Ensure BOTH carriage/flex cables and BOTH ink cartridge contacts are thoroughly clean before
proceeding: http://inkjet411.com/?page_id=1519
