The Epson PX660 stores critical data in a non-volatile memory (EEPROM). This includes:
When the absorption percentage hits 100% (or a specific hex value like FF), the printer enters a “fatal error” mode. The Adjustment Program sends a specific sequence of commands that overwrites the EEPROM values, resetting the Waste Ink Pad counter to 0%. It does not physically clean or replace the padding – that is your responsibility.
Warning: Using the adjustment program does not fix a physically overflowing pad. If you reset the counter without checking the actual pad or installing a waste ink bottle, you risk ink leaking inside your printer and destroying electronic components.

Q: How many times can I reset the counter?
A: Theoretically unlimited. But after 3-4 resets, the pads will physically overflow. You must then open the printer and replace the pads. When the absorption percentage hits 100% (or a
Q: Will the adjustment program damage my printhead?
A: No. The reset function only changes a number in EEPROM. But avoid running unnecessary “head cleaning” loops via the program.
Q: I lost the program – can I use a generic Epson reset tool?
A: No. Generic tools (like for R230 or L800) will brick your PX660. Use only PX660/XP-330 specific version.
