2. Enter 123 (or 124, or 1234) at keypad. The ‘Underware’ menu should be displayed.
3. Use the arrow keys to navigate to the Information Menu. Select Ok.
4. Use the arrow keys to navigate to the 'checksum for relock data input' (or simply ‘checksum’).
Select Ok. LCD should display a 5-digit number after a few seconds.
5. Press Cancel several times to completely exit out of service menu.
6. Attempt to send a print job to printer.
NOTE: with a marginally performing ink cartridge, this typically results in allowing 1 entire print job to be
printed at a time. If this does not permit any print operations then the cartridge has internal micro-
electronic damage and will need to be replaced.
*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 “Incompatible Cartridge(s)" /
“Print Cartridge(s) Problem”, “Refer to printer documentation", "Cartridge is not intended for use in
this printer" / “Remove and check color/black cartridge” error messages are typically indicative of
failed micro-electronics internal to the ink cartridge(s). Also, 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 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 picture at bottom of 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 refilled cartridge). We regret your
inconvenience, and we hope that you will continue to consider the compelling value of inkjet refilling in
the future.
Please let us know if the above test procedure was successful and able to provide any clarity on the HP
95/98 cartridge issue.
