Epson L805 L810 L850 Resetter And Adjustment Program [verified] Jun 2026

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).

2. Key Features (What It Does) | Function | Description | |----------|-------------| | Waste counter reset | Resets protection counter to 0% – essential after physical pad cleaning/replacement. | | Initial ink fill | Forces printer to pull ink from tanks to head (useful after deep clogs or head swap). | | Printhead alignment | Manual bi-directional & uni-directional adjustment. | | Head ID registration | Writes new head’s unique ID into EEPROM – prevents wrong density issues. | | Borderless print counter | Reset if you only use borderless printing (fills pads faster). | | EEPROM dump | Save/load printer EEPROM data (advanced troubleshooting). | Epson L805 L810 L850 Resetter And Adjustment Program

3. Supported Printer Models (Exact)

Epson L805 – Most common. Requires version 1.2.0 or higher for full support. Epson L810 – A3 dye-based printer. Works with program versions 1.0.3 and up. Epson L850 – Multifunction (print/scan/copy). Needs version 1.1.8 or newer (some scan functions may not reset via third-party tools).

⚠️ Do not use L805 program on L810 – different EEPROM addresses. Use a single multi-model tool (e.g., Epson Adjustment Program for L805/L810/L850 ). Initial ink charge – for new or rebuilt printers

4. How to Use (Step-by-Step)

Download the correct program (often named L805_L810_L850_AdjProg.exe ). Disable antivirus temporarily – some resetters are flagged as hacktool (they modify USB protocol). Connect printer via USB (network not supported for service mode). Put printer into service mode :

Turn off printer. Hold Reset + Power buttons, then release Reset after power LED flashes. (Alternative for L850: Hold Stop + Power). Ink system status checks – monitor pad saturation,

Run program – select correct model from dropdown. Choose “Waste ink pad counter” → click Check → Reset . Turn printer off/on – error should clear.
