Compatible Replacement Chip for PSI Color Laser Mail 3640 (non-OEM)

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

Its compatible with the Color Laser Mail 3640/HS, Color Laser Mail 3655 printer models.

This is a killer chip. It locks out and stops you printing. You must replace it each time you refill.

Specific instructions included - it simply fits in place of the original in the chip compartment on the top corner of the cartridge. This is a radio-frequency chip without a physical connector.

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.
