Currently there is no resetter for Pro-1 PGI-29 Chips.
You should not operate the Pro-1 without properly functioning chips. When the printer is operated by overriding the chip when it has become empty, the printer will go about continually priming the head and use a vast amount of ink in doing so.
This ink is diverted into a waste ink absorber and this item is not user serviceable.
Always operate the printer with functional chips. Fortunately there are aftermarket chips. These are one time use and must be changed to a new one each time the cartridge is refilled. Changeout is simple with the modified carts and takes less than a minute for each chip. A few seconds really.
I have been able to get well behaved aftermarket chips for the PGI-29. One note: Make doubly, tripley sure if there is such a word that the correct chips is mounted onto the cartridge before using it. We ship all chips with labels inside each individual bag. Do not remove the included labels and mix them up or else you will be hating yourself. So remove and handle each chip...ONE AT A TIME. This is very important. Chips are not interchangeable and not easily idetifiable as to the model/position/color.
Chips are priced individually and I have a special combination of 12 colors and include an extra Chroma Optmizer chip as experience shows that this tank will be filled the most often. So the Baker's Dozen is 12+1 = 13 chips!
