Adjustment Program For Epson L121 May 2026

Epson printers track ink absorbed by internal waste pads (used during cleaning and ink purging). When the counter reaches a manufacturer-defined threshold, the printer blocks printing and shows an error (e.g., “Service Required,” “Waste Ink Pad Full,” or 0x97 variants). The adjustment program allows resetting that counter so the printer resumes operation. Resetting without replacing or cleaning the physical pads may cause ink overflow.

Resetting the counter tricks the printer into thinking the pads are brand new. However, the physical pads are likely saturated with ink. If you continue printing without addressing this, ink will eventually overflow the pads and leak out of the bottom of the printer.

If you reset the counter without cleaning or replacing the pads, the ink will eventually overflow, leak onto your desk or floor, and potentially damage the printer’s internal circuitry. adjustment program for epson l121
