Every time I get a low ink warning on the black PGBK 220 cartridge, upon visual inspection, the cartridge still contains approximately 20-25% of the ink. Non-OEM cartidges especially have a lot a ink left. Makes me think there's a Canon conspiracy in the printer maintenance software to identtify non-OEM cartidges and generate premature low ink wanings. Anyone else have this problem or know how to overcome it?
There are two types of ink warnings that will appear with your printer: a "low ink" warning and an "out of ink" warning. The "low ink" warning is designed to occur around the 25% mark. The intention is to give the consumer time to purchase replacement ink if necessary and have it available when the "out of ink" error occurs.
Think of it like the low fuel light on a car. While you still have enough gas to travel around, the warning light is a reminder to fill-up at the nearest gas station so you won't be stranded on the road without fuel. In a similar way, we don't want you to be stranded without ink in the middle of an important print job.
