While the software reset clears the digital counter, it does not physically clean the waste ink pads inside the printer. If your printer has genuinely printed thousands of pages for years, these pads may be saturated with ink.
Resetting the counter without replacing the pads could result in ink eventually overflowing and leaking onto your desk or desk electronics. If you notice ink smudging on the bottom of your passbooks or visible leakage, you should contact a professional to replace the waste pads physically.
Need to reset your Epson PLQ-20 (head cleaning count, EEPROM, or other service counters)? The PLQ-20 Adjustment Program is a utility used for maintenance tasks like resetting waste counters, initializing settings, and running diagnostic routines.

is a 24-pin impact dot matrix passbook printer, which typically handles hardware resets and configuration through physical button combinations or a dedicated Service Manual utility intended for technicians [26, 27]. 1. Manual Hardware Reset & Configuration
You can enter the printer's setup mode to reset or adjust settings without external software: Enter Setup Mode: Turn the printer . Hold down the F1 and F2 buttons simultaneously while turning the printer back Adjustment Actions:
From this mode, the printer can print out its current configuration. You can follow the printed prompts to adjust paper alignment, print head gap, or return settings to factory defaults [26]. 2. Common Adjustments Automatic Alignment:
features automatic sheet alignment and print head adjustment
. If these fail, ensure the sensors are clean, as they are critical for precise multi-part form printing. Driver Settings:
Basic print quality and paper size adjustments should be done through the Epson Printer Settings
in the Windows Control Panel rather than a specialized utility [28]. 3. Regarding "Free" Reset Utilities Third-Party Tools:
You may find unofficial "Resetter" tools on third-party forums. Use caution , as these are not authorized by
and can sometimes contain malware or permanently damage the printer's firmware [27]. Official Maintenance:
If the printer requires a "Maintenance Reset" (often indicated by specific blinking light patterns), it usually signals that internal components like the ribbon drive or sensors need professional cleaning or replacement.
