Compatible Replacement Chip for Ricoh MP-C4503 (non-OEM) 

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

Its compatible with these 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.

It fits in place of the original one on the outside of the cartridge.  We do not send specific instructions. 

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. 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.

Save money! Refilling with high quality compatible toner and re-chipping gives excellent results and costs much less than buying an original cartridge.
