This is the most frequent use. Epson printers have internal counters that track how much ink is flushed into the waste ink pads during cleaning cycles. When these counters hit a pre-set limit, the printer stops working and displays an error message stating "The printer's ink pads are at the end of their service life." The adjustment program allows the user to reset these counters to zero, effectively telling the printer the pads are new.
And sometimes, when the bench was quiet and the shop smelled like solder and warm plastic, he would pick up The Adjustment Program and read aloud the printed confidences, stories of patience and repair that the machines had given back to the people who kept them alive. epson m2120 adjustment program
