Let’s tear down what this program actually does, why Epson doesn’t want you to have it, and the precise mechanics of the dreaded "Waste Ink Pad Counter." Unlike traditional cartridge printers where the print head cleaning cycle sends ink back into a cartridge, the M2120 uses a gravity-fed system. When you run a head cleaning, power cleaning, or even just turn the printer on, a small amount of ink is flushed through the print head into an absorbent pad.
