These permanents chips are for HP 940 and 940XL cartridges. They can be installed on any refillable, compatible, or original cartridges. They are designed specifically with refilling in mind.
When refilling HP 940/940XL cartridges or using our HP 940/940XL refillable cartridge system, you have two options for chips: re-using the original chips or installing permanent chips
Note that with both options it will not be possible for the printer to display accurate ink levels. However, with our refillable cartridge system, this is not a problem because the cartridges are transparent so it easy to see how much ink is left inside.
The chips have a peel-off adhesive backing making them easy to install: just position it on the cartridge and press firmly to stick it into place.
The chips are guaranteed against all defects as are all our products.
