Epson will void your warranty the second they see you used an Adjustment Program. Why? Because they want you to pay $150 for a "repair" that takes 10 minutes of labor.
However, the Magnuson-Moss Warranty Act (in the US) suggests that Epson cannot void your warranty just because you used a third-party reset tool unless that tool caused damage. Since resetting a counter does not change the hardware, you are legally on stable ground—but Epson will fight you anyway.
While the software tools are similar, the hardware they support differs slightly.
Key Technical Note: While the L805 and L810 share many mechanical components, they often require specific versions of the adjustment program. Using an L805 program on an L810 can result in communication errors or incorrect calibration because the firmware encryption keys and USB IDs differ.

One day, your L850 will stop printing. The screen will flash: “Service Required. Parts inside your printer are at the end of their service life.”
Panic sets in. You check the ink tanks—they are full. You clean the nozzles—nothing. You call Epson support, and they tell you the dreaded phrase: “You need to send it in for a mainboard reset and pad replacement.”
Here is the truth: Your printer is mechanically fine. There is nothing broken. Epson will void your warranty the second they
If the process was successful, the printer should initialize without the red light flashing, and the error message on your computer should disappear.
The Epson Adjustment Program (Version 1.6.0 or higher for these models) is the proprietary service software that Epson technicians use. It is not sold in stores. It is leaked into the wild.
This program bypasses the user-level driver and speaks directly to the printer's NVRAM (Non-Volatile RAM) on the mainboard. Key Technical Note: While the L805 and L810
If you own an Epson EcoTank (or ET-series) printer, you were sold on a dream: “Print thousands of pages without buying cartridges.” And for the most part, that dream holds up.
But there is a silent killer hiding in the firmware of your Epson L805, L810, or L850. It isn't a clogged print head or a paper jam. It is a ghost in the machine called the Waste Ink Pad Counter.
Today, we are going to strip away the marketing fluff and look at the harsh reality of printer maintenance. We will explore what the Adjustment Program (often called a Resetter) actually does, why Epson forces you to hit a wall at 100%, and how to legally and safely navigate this problem.
It is important to note the legal and safety implications of these tools.
