Gives types of chips to use, sales in USA, and certain things to take note of.
The toner reset chip replaces the original HP ID chip and is designed to be used only on refilled HP cartridges.
It is not recommended to force toner cartridges to run on empty, as this can cause damage to both the printer and the toner cartridge.
The reset chips are dedicated to one color only, so that user can not swap toners.
As for actual physical installation, just push the new ID chip in until it clicks into place. The correctly manufactured ones should be a snug fit.
I have seen techs using a drop of contact glue behind the chip-board to secure it.
Copper pads face outwards towards matching printer pins.
See photo for polarity 'square' pad.
My printer is Samsung, not HP, so your toner cartridge may be a different shape.
