It resets the waste ink pad counter. Epson printers have a service life for absorbent pads that collect ink during cleaning cycles. Once the counter hits a limit (usually ~15000–20000 cleaning cycles), the printer locks down with a “Service Required” error (e.g., flashing lights or “Parts inside printer at end of service life”).
The Epson Adjustment Program (also called AdjProg, Resetter Tool, or WIC Reset) is a service utility designed for technicians. It resets the printer’s internal waste ink counter. When your Epson L380, L383, L385, or L485 shows a “Service Required” error (flashing lights or message: “Parts inside your printer are at the end of their service life”), the printer stops working until this counter is reset.
Why does this happen?
Inkjet printers have a sponge/pad that collects ink during cleaning cycles. The printer tracks absorbed ink volume. After ~5000–15000 cleanings, it locks down to prevent overflow. Epson expects you to replace the pads (or install a waste ink tank) before resetting.
