If you see any of these on your PX660, you are a candidate for running the adjustment program:

Calibrates the physical position of the printhead to fix ghosting or blurry prints.

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 . This is NOT because the pad is dangerously full, but because the counter has hit its ceiling.

if you are uncomfortable with disassembling electronics or using unsigned software, pay for a professional repair. One mistake (e.g., shorting the mainboard while installing a waste tank) will kill your printer permanently.

Try these troubleshooting steps:

To understand the Adjustment Program, you must first understand the waste ink system. Every time the Epson PX660 performs head cleaning or prints, a small amount of ink is diverted to internal absorbent pads called "waste ink pads." The printer tracks this ink usage via an internal counter. This counter does have a physical sensor—it is simply an estimate based on printer usage. When the counter reaches a predetermined maximum value, the printer locks itself down to prevent potential ink overflow and damage. This results in the printer refusing to print, accompanied by flashing LEDs and error messages like "Service Required" or error code E-11.

❌ Both the Adjustment Program and WICReset require a direct USB connection to a Windows PC. Wi-Fi or network connections will not work for resetting the waste ink counter.

Resetting the digital counter does not empty the physical waste ink pads. If you reset the printer multiple times without replacing the physical felt pads or installing an external waste ink tank, ink will eventually leak out of the bottom of the machine.
