The Epson PLQ-20 Adjustment Program is a specialized service utility used to reset internal maintenance counters, such as the waste ink pad counter, and calibrate hardware components on the PLQ-20 passbook printer.

Furthermore, “free” does not absolve you of physics. Resetting the counter without physically cleaning or replacing the ink pad is a temporary fix. The pad will eventually saturate.
