The Adjustment Program (often called a resetter utility or service tool) is an official Epson service utility designed for technicians. Unlike standard printer drivers, this low-level tool communicates directly with the printer’s firmware to reset internal counters, perform ink charging, and troubleshoot hardware failures.
For the Epson PX660, the program is essential for resetting the Waste Ink Pad Counter. Every Epson inkjet printer has a spongy pad inside that absorbs ink during cleaning cycles. Epson programs the printer to stop working after a set number of cleaning cycles (usually 15,000 to 30,000 page cleanings) to prevent ink overflow. The Adjustment Program tells the printer: “The pad has been replaced or cleaned – reset the counter to zero.”

It’s a Windows-based utility that communicates directly with your printer’s EEPROM. It can:
It is not an official Epson tool for end-users, but rather a service tool leaked from authorized service centers.
Adjustment utilities connect to the printer via USB (or network in some cases) and send special service commands recognized by the printer’s firmware. These commands can: The Adjustment Program (often called a resetter utility
The utility typically reads status codes from the printer and displays counters and error flags so the operator can decide which actions to run.
If you see any of these on your PX660, you are a candidate for running the adjustment program:
This is the trickiest part. Many websites offer “free” adjustment programs, but they are often bundled with viruses, trojans, or ransomware. Follow these rules: It is not an official Epson tool for
Epson printers use a self-cleaning mechanism. Every time you turn on the printer or perform a head cleaning cycle, a small amount of ink is pumped through the printhead into a sponge-like “waste ink pad” inside the machine. This prevents clogs and ensures print quality.
Over months or years, these pads fill up with ink. Epson engineers designed a counter to track this. Once the counter reaches a preset limit (e.g., 15,000 cleaning cycles), the printer locks itself down. This is NOT because the pad is dangerously full, but because the counter has hit its ceiling.
The official Epson solution: Replace the pads (a messy, complicated teardown) or buy a new printer.
The smart user’s solution: Run the Epson PX660 Adjustment Program to reset the counter to zero. This buys you hundreds more prints. (Note: You should eventually place a container to catch any overflow ink, but the program solves the software lock.)
