Epson PX660 Adjustment Program — Complete Guide What it is The Epson PX660 adjustment program (also called a service utility, reset utility, or service tool) is a Windows application used to perform maintenance and reset operations on Epson Stylus Photo PX-660 series printers. It’s typically used by technicians and advanced users to resolve service-related errors, clear waste ink counters, initialize certain internal settings, and perform advanced servicing functions not available in standard drivers. Common uses
Reset Waste Ink Pad Counter: Clears the “service required” or “waste ink pad is at the end of its service life” message so the printer returns to normal operation. EEPROM Read/Write: Back up or restore internal printer settings. Head Cleaning / Alignment: Run deep cleaning cycles and perform nozzle checks or head alignment beyond what the standard driver offers. Initialize/Set Counters: Reset other internal counters (e.g., print head usage, page count) used by diagnostics. Manual Ink Charge / Ink Pumping: Prime ink lines after cartridge changes or maintenance. Motor and Sensor Tests: Exercise steppers, fans, sensors, and perform movement tests for troubleshooting mechanical issues.

When to use it Use the adjustment program only when:
The printer displays service errors that block printing (e.g., waste ink counter message). You’ve performed hardware maintenance that requires resetting counters (e.g., replacing or cleaning waste ink pads, major head cleaning). You need deeper diagnostics to identify hardware faults.
Do not use it for routine printing tasks. Resetting counters without proper maintenance (like replacing/cleaning the waste ink pads) can lead to ink overflow and damage. Risks and precautions Epson PX660 Adjustment Program — Complete Guide What
Warranty: Using third-party or unofficial service utilities may void warranty. Prefer official Epson service centers if the printer is under warranty. Ink overflow: Resetting the waste ink counter without servicing or replacing/cleaning the waste ink pads can cause ink to overflow inside the printer, leading to hardware damage and smell. Wrong settings: Incorrect EEPROM writes or applying settings meant for other models can brick the printer. Malware risk: Only obtain tools from reputable sources—some downloads circulating online may include malware. Data loss: EEPROM operations can change serial numbers or internal settings; back up before writing anything.
How to prepare (step-by-step)
Turn off the printer and ensure it’s on a stable work surface. Gather tools: small screwdriver set, lint-free cloths, gloves, and paper towels for any ink spills. If resetting waste ink counters, open the printer and inspect/replace or clean the waste ink pads or install an external waste tank. Never just reset without physical maintenance. Install the official Epson driver so Windows recognizes the PX-660. Obtain the correct adjustment program version for PX-660 (preferably from an authorized service source). Verify file integrity and scan for malware. Run the adjustment program as Administrator in Windows compatibility mode if needed. Back up EEPROM/settings before writing changes. EEPROM Read/Write: Back up or restore internal printer
Typical reset procedure (waste ink counter) — concise
Power on printer and connect via USB. Open adjustment program and select model PX-660. Read current waste ink counter value (note it). If you have serviced or replaced waste pads, choose “Reset” or “Clear” for the waste ink counter. Apply reset and power cycle the printer when prompted. Print a test page and monitor for leaks or abnormal behavior.
