1. What Is This Program?

Unlike a simple waste ink counter resetter, this is an official or reverse-engineered service tool (often based on Epson’s own Adjustment Program) that allows:

  • Waste ink pad counter reset – prevents the “Service required” error (usually after 15,000–20,000 pages).
  • Initial ink charge – for new or rebuilt printers.
  • Head ID input – after replacing the printhead.
  • Bi-D adjustment – fix horizontal banding.
  • Ink system status checks – monitor pad saturation, borderless printing usage.

It works specifically for Epson L805 (A4 photo printer), L810 (A3 model, rarer), and L850 (A4 all-in-one with CD printing).

Step 4: Resetting the Counter

  1. In the main menu, click on Particular Adjustment Mode.
  2. Under the "Maintenance" section, select Waste Ink Pad Counter.
  3. Click OK.
  4. You will see a box with "Main Pad Counter." Check the box next to it.
  5. Click the Check button to see the current value (it will likely be near 100%).
  6. Click the Initialization button to reset the counter to zero.
  7. A message will appear asking you to turn the printer off. Turn the printer OFF and wait a few seconds.
  8. Turn the printer ON.

Epson L805, L810, L850 Resetter & Adjustment Program: A Complete Guide

Inkjet printers from Epson’s EcoTank and high-volume series—specifically the Epson L805, L810, and L850—are renowned for their print quality and low running costs. However, like all precision devices, they eventually require maintenance. When your printer displays messages like “Service Required”, “Parts at the end of their service life”, or a flashing red light pattern, you are likely facing a need for the Resetter and Adjustment Program (often called the AdjProg).

The Technical Reality: Why the Counter Exists

Inside every Epson inkjet printer lies a "spittoon"—a set of felt pads. Every time you clean the print head or turn the printer off, the printer pumps a small amount of ink into these pads to prevent clogging. Eventually, these pads saturate. Epson programs the printer to stop working after approximately 8,000 to 15,000 pages (depending on the model) to prevent ink from leaking inside the machine.

Crucial Warning: The Adjustment Program lies to the printer that the pads are empty. It does not physically dry or clean the pads. If you reset the counter three or four times without physically cleaning or replacing the pads, ink will leak out the bottom of your printer, destroying your desk and possibly the printer’s power supply.
