NOTE 2: Ideally, a good Color cartridge will display 300 nozzles (for example, check the printed 10 x 10
stair step patterns for each of the 3 colors), while a good Black cartridge will display 416 nozzles (for
example, check the printed 26 x 16 stair-step pattern).
NOTE 3: Ensure the top cover is closed and that the interlock switch at top-right side is properly closing
the circuit – you may need to depress with a small pencil to ensure this is not causing a false error
condition.
*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 “Print Cartridge Not intended
for use in this printer” / “Cartridge Error - Cartridge not right for this printer" error message is typically
indicative of failed micro-electronics internal to the ink cartridge(s). As well, 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.
Now, 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 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.

SEVERE ERROR MESSAGES – HP 92-98 Rejection (> No Tap 41)
Regarding your recent inquiry about the HP 92 cartridge error message ("cartridge is not intended for
use in this printer") and inability to print to your HP PS C4180 printer, this type of problem is either an
electrical connection issue between the printer and the cartridge, or more likely, an internal micro-
electronic failure inside the cartridge. An electronic failure of the cartridge would be unrelated to the ink
cartridge refill process; these same failures can occur with brand new ink cartridges*.
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 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.
