how to : take prinrs from hp laser printer if the cartridge is empty

In most of the HP Laser printer models carteidge has a small electric chip  which keeps track of number-of-prints taken by that specific carteidge. This helps maintain quality of print because the toner manufecturer knows approximately how many prints can be done with the amount of Ink  that exist inside the toner/cartridge. Upon reaching that number the chip on toner tells printer to stop printing. At that stage printer start showing an error message on printer display LCD panel to indicate that print limit is reached and now toner must be replaced. This is a good feature by printer manufacturer because it also shows that how much further printing could be possible with current toners. The printer LCD always shows Ink levels. This helps you to identify when you have to replace a new toner/cartridge to avoid emergency breakdowns in printing.

However, this feature sometimes becomes annoying when Ink powder inside toner is not fully consumed but the number of print-outs in toner chip ends. This happens often because everytime you send a print to printer doesn't include all color shades. Sometime you are printing a page with most part of the page with red content, but a very little amount of yellow or meganta. Similar happens with other color shades. A very few print-outs are that who are using average quantity of ink from all toners at the same time. But every-time you print, the chip on cartridge considers that this print-out consumed average amount of Ink powder and it subtract 1 from total allowed print-outs.

Finally sometime Yellow toner ends first, sometime Magenta, sometime Cyan, sometimes Black toner ends first. Then immediately printer stops printing and asks you to Replace a Cartridge / Toner. However the ink powder inside still has capacity to print few more pages. At this stage you can Force your printer to print and ignore / override the error message.

I tried it with HP Color Laser Jet CP2025 printer and HP Color Laser jet 3600 printer but believer me, most HP printers have this capability.
