This type of fatal cartridge error (i.e. "refer to documentation" / "incompatible cartridges", etc.) typically indicates the internal micro-electronics of the HP #74/75 cartridge are damaged. The cartridge's electrical wire runs at rear and lower side of the ink cartridge, are very delicate and are somewhat susceptible to ink attack over time, which can lead to premature failures. However, our test group has also seen these failures with brand new cartridges. In addition, the older the cartridge the higher the chance of an internal electrical failure. I suggest you first run a 'Tap 41' diagnostic test to check cartridges electrical health (this is a forced test); you may also bypass the error (temporarily) on most models which use HP 74/75 cartridges.
