Compatible Replacement Chip for Oki MC851 (non-OEM)  

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

Its compatible with the MC851+/MC861+/MC861/861dn/861cdn MFP models. 

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.

Specific instructions included - It fits in the chip compartment on the top corner of the cartridge. The Starter Cartridge is missing the chip and is not refillable. This is a radio-frequency chip without a physical connector.

Its for Europe region only.

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. We supply the chips only. 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.
