Epson L4150 , L4160, and L4170 Resetter Adjustment Program: A Complete Guide
If you own an Epson L-series printer, you may eventually encounter a frustrating error message stating that "A printer's ink pad is at the end of its service life" or "Service Required." This guide explains how to use the Epson L4150, L4160, and L4170 Resetter Adjustment Program (often called the AdjProg) to resolve these issues and get your printer back to work. What is the Epson Adjustment Program?
The Epson Adjustment Program is a specialized utility tool designed for maintenance and repair. While used by technicians, it is also available for users to perform "Waste Ink Pad Resets."
Every Epson printer has internal sponges called waste ink pads that collect excess ink during head cleanings and printing. The printer uses a digital counter to estimate when these pads are full. Once that counter reaches its limit, the printer locks itself to prevent ink overflow, even if the pads aren't physically leaking yet. Key Features of the Resetter for L4150, L4160, and L4170
The software is compatible with several models in the L-series eco-tank range:
Waste Ink Pad Counter Reset: The most common use—zeroing out the counter to unlock the printer.
Print Head Cleaning: Performs a deep clean more powerful than the standard driver utility.
EEPROM Initialization: Resets the printer's internal memory settings.
Ink Charge: Forces ink through the tubes, useful after a long period of inactivity. How to Use the Resetter (Step-by-Step) Epson L4150 L4160 L4170 Resetter Adjustment Program

Resetting the software does not physically clean the ink pads. If you reset the counter multiple times without checking the hardware, ink may eventually leak out of the bottom of the printer. It is highly recommended to: Physically inspect the waste ink tank. Clean or replace the sponges if they are saturated.
Install an external waste ink bottle (waste ink mod) for heavy users. Safety and Compatibility

Epson L4150 series are workhorses, but they have a built-in "odometer" for their waste ink pads. When that counter hits 100%, the printer stops with a "Service Required" error and flashing red lights.
Here is a short story about a typical user facing this "digital wall" and the software that tears it down. The Day the Printing Stopped Elias had a deadline. His Epson L4160
had been humming along perfectly for years, its EcoTank thirsty for ink but always delivering. But today, halfway through a 50-page report, the rhythm stopped. The printer didn’t just jam; it quit. Two red lights—the ink and paper symbols—began a frantic, alternating dance. On his computer screen, a grim notification appeared:
"The printer's ink pad is at the end of its service life. Please contact Epson support." The Digital Ghost in the Machine
Elias knew the pads weren't actually "broken." They were just sponges designed to catch excess ink from head cleanings. But Epson’s internal software had decided they were "full" based on a mathematical counter, not a physical sensor. To the printer, Elias was at a dead end.
The Epson L4150, L4160, and L4170 Adjustment Program (also known as a "Resetter") is a specialized service utility used to fix the "Service Required" or "Ink Pad Full" error. When these printers perform head cleanings, waste ink is pumped into internal absorbent pads. A digital counter tracks this usage, and once it reaches 100%, the printer locks itself to prevent ink overflow and potential damage. The Story of the "Locked" Printer
Imagine you are finishing a critical print job when your Epson L4150 suddenly stops. Instead of a fresh page, you get alternating blinking lights and a message: "A printer's ink pad is at the end of its service life". While the hardware might still be in perfect condition, the software "kill switch" has been triggered. At this stage, you have three paths:
The Epson L4150, L4160, and L4170 Adjustment Program (often called a "Resetter") is a critical maintenance utility used to resolve the "Service Required" error. This error occurs when the printer's internal waste ink pad counter reaches its preset limit, effectively locking the device to prevent ink from overflowing and causing internal damage. When to Use the Adjustment Program It sounds simple
You should only use this tool if you encounter the following symptoms:
Error Message: Your computer displays "The printer's ink pad is at the end of its service life" or "Service Required".
Indicator Lights: The power, ink, and paper lights on the printer blink alternately or simultaneously.
Locked Functionality: The printer stops printing entirely, even if the ink tanks are full and there are no paper jams. Step-by-Step Guide to Resetting the Waste Ink Counter
The reset process involves clearing the digital counter that tracks waste ink saturation.
You downloaded the tool, but it isn't working. Here is why:
Error: "Communication Error (Code 200000xx)"
Error: "Model Mismatch"
Error: "Reset Failed – Check Box Counter"
Follow these instructions precisely. Incorrect steps could corrupt your printer’s EEPROM.
Absolutely. The Epson L4150 L4160 L4170 Resetter Adjustment Program is arguably the most valuable tool for long-term EcoTank owners. It transforms a “dead” printer into a fully functional machine with just a few clicks.
That said, always combine the software reset with common sense. If you’ve printed thousands of pages, inspect the physical waste pad. A little preventive maintenance will keep your Epson running for years without needing another reset.
