Your toner cartridge will shut down at every 2,500 page cycle, leaving you unable to print, even though there may be plenty of toner left in the cartridge. Slash printing costs by simply replacing the chips which shut the cartridges down, to extend toner cartridge life by up to 30-40%, or use the chip if you are refilling the cartridges, to get them working again.

Contents:

- 1 x HP Q5949A Toner Reset Chip

- Each chip lasts for one cycle of 2500 printed pages, after which it must be replaced again.

- 1 x set of illustrated, easy to follow instructions. The procedure takes about twenty seconds for each unit and requires only a small sharp knife.
