How to Extend the Life of Printer Ink Cartridges in 1-Step

Sep 20, 2012 1 Comment by

Don’t you just hate when the first thing that pops up when trying to print something is a low-ink notification? Well, there may be a way around that, or at least until your replacement cartridge(s) arrive. Let’s just say all you need is a standard paperclip and compatible ink cartridges.

Most consumer inkjet printers, such as those made by Canon, HP, and Lexmark (but not Epson) use a thermal inkjet; inside each partition of the ink reservoir is a heating element with a tiny metal plate or resistor. In response to a signal given by the printer, tiny current flows through the metal or resistor making it warm, and the ink immediately surrounding the heated plate is vaporized into a tiny air bubble inside the nozzle. As a consequence, the total volume of the ink exceeds that of the nozzle. An ink droplet is forced out of the cartridge nozzle onto the paper. This process takes a matter of milliseconds.

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.
