However, if your printer works routinely after inserting a brand new HP56 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.
For any additional questions please contact us directly: [e-mail]

HP OFFICEJET J3680/4215/4315/5510/5610/6100/6110 - ERROR MESSAGES (HP 21/22/27/28/56-58
CARTRIDGES)
Regarding your recent inquiry about the HP56 black.........OR.........HP57 color ink cartridge error
message ("remove and check cartridges") and inability to print with your HP OJ 6110xi printer, this type
of problem is typically an internal micro-electronic failure inside ONE OF THE INK CARTRIDGES (it is very
rare for both ink cartridges to suffer electrical failures at the same time!) - likely due to natural micro-
electronics degradation from internal ink corrosion. 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*. Please perform the following diagnostic steps....
Please verify the age of the ink cartridge(s)....look at imprinted date on front (or back) of ink cartridge. If
this ‘warranty expiration date’ has expired, then potential cartridge failures can occur due to internal
corrosion, etc.
NOTE: Unfortunately, alignment pages and internal self test prints will usually print Ok eve n 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.
DIAGNOSTIC CHECKS:
A. Clean cartridge/printer electrical contacts. Also inspect printer's internal carriage flex cables for
surface damage (i.e. burn marks) or an uneven contact surface (by which the cartridge's rear electrical
contacts mates with).
