Epson L4150 L4160 L4170 Resetter Adjustment Program [FAST]

The adjustment program is flagged as a “hacktool” by most antivirus software. Disable real-time protection temporarily.

Epson inkjet printers utilize a service-required internal counter that tracks the volume of ink flushed into the maintenance box (waste ink pad). Once this counter reaches a predetermined limit, the printer locks operation and displays a "Service Required" error (e.g., "Parts inside your printer are at the end of their service life"). The Adjustment Program (commonly called a resetter) is a proprietary service tool used to reset this counter, initialize specific mechanical adjustments, and restore full printer functionality.

Here is the most critical part of this article: The Adjustment Program resets the counter, but it does not replace the waste ink pad.

If your printer has genuinely absorbed a high volume of ink (e.g., after 3+ years of heavy use), the physical pad might be saturated. Resetting the counter without replacing or cleaning the pad can lead to ink leaking inside your printer, potentially ruining the power supply unit or mainboard.

Because these programs are hosted on file-sharing sites, forums, and obscure blogs, they are prime targets for malware distributors. Many ".exe" files claiming to be "Epson Resetters" are actually Trojans designed to steal data or encrypt your files. Always scan these files with a robust antivirus program before running them.
