| Adjustment | Purpose | |-------------|---------| | Head angle adjustment | Corrects banding/double printing | | Bi-D adjustment | Aligns bidirectional printing | | PW adjustment | Detects paper edges correctly | | Injection check | Verifies nozzle health |
⚠️ Skipping adjustments may cause poor print quality after reset.
When searching for "Epson L4150 resetter," you will find two main solutions. Which is better?
| Feature | Free Adjustment Program (AdjProg) | Paid WIC Reset Utility | | :--- | :--- | :--- | | Cost | Free (but hard to find legit files) | Pay-per-reset (approx. $10) | | OS | Windows Only | Windows & Mac | | Skill Level | Advanced (Service mode required) | Beginner (1-click) | | Risk | High (Bricking if wrong button clicked) | Low | | Additional features | Full calibration suite | Only resets counters |
Verdict: If you are technically confident, use the Adjustment Program. If you just want to print again and don't mind paying $10 for convenience, use WIC Reset. Epson L4150 L4160 L4170 Resetter Adjustment Program
Modern Epson printers are notoriously stubborn. The L4150/60/70 series often rejects older versions of the adjustment program. If the software version doesn't match the firmware, the printer will reject the code, leaving you exactly where you started—or worse, in a mode you cannot exit.
The Epson L4150 L4160 L4170 Resetter Adjustment Program (often abbreviated as AdjProg or WIC Reset) is a proprietary service utility designed by Epson for technicians. However, it has been leaked to the public to allow advanced users to service their own machines.
Unlike a simple driver or firmware update, this program interacts directly with the printer’s Non-Volatile Memory (NVRAM). Its primary job is to reset two critical counters:
Abstract: Epson’s EcoTank L4150, L4160, and L4170 series printers utilize a permanent print head and an ink tank system designed for high-volume printing. To manage print lifecycle events—specifically the exhaustion of the waste ink pad counter—Epson incorporates a service-required timer. This paper examines the third-party Resetter Adjustment Program (often referred to as a "keygen" or "adjustment program") designed to reset these counters. We analyze its operational mechanics, legitimate use cases, inherent risks, and legal implications. | Adjustment | Purpose | |-------------|---------| | Head
If you own an Epson EcoTank printer—specifically the popular L4150, L4160, or L4170 models—you have likely experienced the dreaded “Service Required” or “Parts End of Service Life” error. This message usually appears as a flashing error state on your printer’s screen, preventing any further printing, scanning, or copying.
For many users, the immediate reaction is panic, followed by a costly trip to a repair shop. However, there is a powerful, software-based solution: The Epson L4150 L4160 L4170 Resetter Adjustment Program.
In this detailed guide, we will explain what this program is, how it works, the risks involved, and a step-by-step walkthrough to get your printer back to life.
The Epson Adjustment Program (often called a "resetter" or "waste ink pad counter resetter") is a proprietary utility tool originally designed for authorized Epson service centers. It communicates directly with the printer’s firmware to reset internal counters. ⚠️ Skipping adjustments may cause poor print quality
Your Epson L4150, L4160, or L4170 has an internal waste ink pad. This pad absorbs excess ink during print head cleaning cycles. The printer tracks how much ink has been flushed into this pad. Once the counter reaches a specific limit (usually around 15,000 to 20,000 pages), the printer locks down to prevent ink overflow, which could damage the printer internally or cause a mess.
The resetter adjustment program forces the counter back to zero, making the printer believe the waste pad is brand new.
To understand the resetter, you first have to understand why your printer is "broken."
Inkjet printers clean their print heads by spraying a small amount of ink into a absorbent pad at the bottom of the machine. Over time—usually after thousands of cleaning cycles—this pad becomes saturated. Epson programs a counter into the printer firmware to estimate when the pad is full. Once that counter hits its limit, the printer locks itself to prevent ink from overflowing onto your desk or damaging the electronics.
It’s a safety feature, but it feels like a planned obsolescence tactic. The official solution from Epson is usually a service center visit, which can cost as much as a new printer.
