Question : Extend HP Color LaserJet 2600n toner cartridge usage beyond “empty”?
My printer was printing out black text just fine, suddenly flashed a message I needed to replace the black toner cartridge and stopped working. My old LaserJet 2 would let me take the cartridge out, rock it back and forth to fill the toner holes and I would get more mileage out of it, even letting me print pages with obvious light streaks in it even with the “replace cartridge” message flashing. This new printer gave no warning and even taking the cartridge out and shaking/rocking it did not let me get any more pages out of it.

Does anyone know how to “fool” this printer so I can at least limp along until I buy a new cartridge? I know some printers you can cover a sensor or hole with tape to fool it…

The HP 2600 has a smart chip in the cartridge. It’d be more expensive to try and fool it than replace it.
