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...Extend HP Color LaserJet 2600n toner cartridge usage beyond ';empty';?
Yes, you can override that to allow continued printing. Below is the text straight from the User's manual (page 94 in my manual):





The HP Color LaserJet 2600n printer displays an Order supplies message when a cartridge is running low and a Replace supplies message when a cartridge has been depleted. To ensure optimal print quality, HP recommends replacing a cartridge when the Replace supplies message is displayed. Replacing the cartridge at this point can help prevent waste of media or other cartridges when one cartridge produces poor print quality.





The Cartridge Out Override feature allows the printer to continue using a cartridge that has reached the recommended replacement point.


WARNING! Using Override may result in unsatisfactory print quality and unavailability of certain features (such as toner remaining information).


WARNING! All print defects or supply failures incurred when an HP supply is used in Override will not be considered defects in materials or workmanship in the supply under HP's Print Cartridge Limited Warranty Statement.





Configuration


Cartridge Out Override can only be enabled from the printer's control panel menu.


1. From the main menu, press (RIGHT ARROW) to System setup and press Check Mark button (SELECT).


2. Press (RIGHT ARROW) to Print quality and press the Check Mark button (SELECT).


3. Press (RIGHT ARROW) to Replace supplies and press Check Mark button (SELECT).


4. Press (RIGHT ARROW) to Override out and press Check Mark button (SELECT).


5. Press (Check Mark button SELECT).


If Stop at out is selected, the printer will stop printing when a cartridge reaches the recommended replacement point. If Override out is selected, the printer will continue printing when a cartridge reaches the recommended replacement point. The factory default setting is Stop at out.





On-going operation


Override can be enabled or disabled at any time, and does not have to be re-enabled for each cartridge. The printer will automatically continue printing when a cartridge reaches recommended replacement. The printer will display a message Replace supply Override in use while a cartridge is used in Override mode. When the cartridge is replaced with a new supply, Override will de-activate until another cartridge reaches recommended replacement.





Best of luck, Hope that helps.Extend HP Color LaserJet 2600n toner cartridge usage beyond ';empty';?
Unlike your laserjet 2, your 2600 has a smart chip.





You cannot fool it. The chip acts as an on/off switch. When the printer determines the cartridge is empty it turns it off.
The HP 2600 has a smart chip in the cartridge. It'd be more expensive to try and fool it than replace it.
