The Adjustment Program is a specialized utility used by technicians to calibrate the printer and reset internal counters. Every Epson printer has a built-in "Waste Ink Pad Counter." Once this counter reaches a specific limit, the printer locks itself to prevent ink from overflowing and damaging the internal hardware.

If you reset the printer more than twice, the physical felt pads inside are likely saturated. You should replace the maintenance box or the pads to avoid ink leaking onto your desk.

Necessary after replacing major internal components.
