NOTE 3: Cartridge Error Bypass Message (Emergency Printing only): The Pen Recovery Level 1 cl ears ca rtridge errors
and permits you to print the TEST PAGE with the normal MENU / TOOLS / PRINT TEST PAGE choice.
*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 Print
Cartridges" / “Check print cartridge" / “Color cartridge is not compatible. Use appropriate HP
cartridge" error messages are typically indicative of failed micro-electronics internal to the ink
cartridge(s). 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. 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 bottom image at this page:

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 ink refill purchase). 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 you have any questions on the technical information provided above.

HP DESKJET D4100 SERIES - NOT RECOGNIZING CARTRIDGE (92-93)
Regarding your recent inquiry about the HP92/93 cartridge error message ("???") and inability to print
to your HP DESKJET 4160 printer, this type of problem could be an electrical connection issue between
the printer and one of the ink cartridges, or more likely, there is an internal micro-electronic failure
inside one of the ink cartridges. 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.* To determine
which cartridge is causing the issue and/or to confirm an electrical problem with one of the ink
cartridges (or both cartridges which is 'very' rare), please perform both the Internal Self-Test page along
with the Cartridge Health diagnostics ‘Tap 41’ test to evaluate the electrical condition of both ink
cartridges....
Please first 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.
