Canon PFI-1000GY Compatible Gray Ink for PRO-1000

No. You keep your original Canon PFI-1000 tanks. Our ink replaces the ink inside them, not the cartridge.

Most first-time refillers start with Method A, no modification: let a tank run completely empty, refill it, and install a fresh one-time chip. The only tool it needs is a High-Pressure Squeezy Cap Combo.

If you print steadily and want the lowest cost per print, the Low Ink Warning System (Method B) tops tanks off before they run empty and never needs replacement chips.

82 ml is exactly one full PFI-1000 tank, predispensed. Refill a completely empty tank with one bottle and there is nothing to weigh or measure.

No. PFI-1000 chips cannot be reset. Method A uses a fresh one-time chip at each refill so the printer tracks ink accurately. On the sensor system path the original chips stay in place and no replacements are needed.

Not on Method A. The one-time chip tells the printer the tank is full, so the tank must be completely empty before refilling. Topping off a partly full tank is exactly what the sensor system path is for.

Red is the one PFI-1000 color we still ship as Canon OEM. Our 12-color sets pair the 11 Precision Colors compatible inks with the genuine Canon Red.

Both supported methods carry a built-in safeguard. Method A keeps the printer's ink tracking accurate through the empty-tank chip cycle. Method B physically watches the ink level and warns before a tank runs low.

We have formulated and shipped refill ink for more than 25 years, and our pigment inks are matched to the OEM formulation your printhead was designed for.
