Compatible Replacement Chip for HP Laserjet Managed MFP E77422 (non-OEM) 

The chip resets the toner cartridge, so you can refill it and use it for another lifetime.

Its compatible with the LaserJet Managed MFP E77422dn/MFP E77428 only. 

There is a killer chip. It locks out and stops you printing. You must replace it each time you refill to reset the cartridge and restore full functionality.

The chip is located inside the end panel. Attaches to the connector cable in place of the original chip. Specific instructions included. 

Its for all regions of the world (Worldwide). 

Available for the Black, Cyan, Magenta or Yellow, or as a Rainbow Pack with each of the four colours.

Please note you also need the correct toner powder for use with this model. These are the chips only but toner bottles are available at TonerTopUp. The cartridge must be full of toner when you install the new chip or it will be useless.

Environmentally friendly!  Refilling cartridges saves raw materials, landfill waste, energy and CO2 emissions.
