The Epson M2120 monochrome multifunction printer utilizes a proprietary service tool known as the "Adjustment Program" to perform maintenance tasks such as resetting the waste ink pad counter, initializing EEPROM, and adjusting printhead alignment.

This paper examines the program’s technical functions, the consequences of unauthorized use, the legal framework (DMCA Section 1201, EU Copyright Directive), and safer alternatives for end‑users.

Inkjet printers track internal maintenance data, including waste ink volume.
