If you’ve got an ink jet printer then you’re likely spending a lot of money on ink. Most of these printers use expensive and sophisticated ink cartridges. These cartridges monitor usage and estimate the amount of ink remaining. The estimate is usually conservative, meaning it indicates you are out of ink before you’re really out of ink.
If you reset this memory then you can keep printing until the cartridge is actually empty. Depending on the brand and model of cartridge, this reset is actually really easy. If you look above the small circuit board on the cartridge, there is sometimes a pinhole reset button, kind of like the paperclip eject hole on most cd rom drives.
