If it is the same as a Copyjet (no M), make sure you haven't got the
cartridges swapped.
They are keyed and I think I may have done that once on mine.

My HP Copyjet M shows one cartridge to be empty (or the need to check)

this sensing either hardware or software? I have tried several other
cartridges and they all seem to get the same indication.
