The only reason cartridges have a limited refill life is the resistors that control the current to each outlet jet. When a cartridge runs out of ink, the resistors can overheat and burn out. Most printers will warn you of a low cartridge before it completely runs out of ink. At the first sign of low ink, refill or top off your ink cartridge to ensure a long refillable life.

When the printer gives the command for an inkjet nozzle to print, many things happen. A certain quantity of ink is already in the firing chamber, having been pulled there by capillary, gravity or vacuum action after the last firing. The electronics package (the copper circuitry on the side of the cartridge) instructs the heating resistor to heat the ink in the chamber, causing it to expand. This very quick expansion forces ink to shoot through the print head nozzle on to the paper.

The number of times a cartridge can be refilled or recycled varies from cartridge to cartridge. On average, a cartridge can be refilled/recycled 3-5 times. Please keep in mind this is an average. Each product varies in the number of times it can be refilled or recycled. The condition of the cartridge must also be considered. You cannot successfully refill a cartridge that has been out of your printer for more than a few hours. The nozzles, when exposed to air, will clog up.
