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)

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 are popular EcoTank printers known for high-volume printing. However, like most inkjet models, they eventually trigger a "Service Required" error. This error occurs when the internal waste ink pads are officially "full" according to the printer's firmware. The Resetter Adjustment Program is the utility used to clear this counter and restore printer functionality. Understanding the Waste Ink Counter
The Mechanism: Printers use porous pads to collect excess ink during head cleaning and borderless printing.
The Logic: A digital counter tracks ink usage; once it reaches a set limit, the printer locks to prevent ink overflow.
The Symptoms: Red lights flash alternately, and a message appears on the computer screen stating "A printer's ink pad is at the end of its service life." The Role of the Adjustment Program
The Adjustment Program (often called "WicReset" or "AdjProg") is a maintenance tool used by technicians. Its primary functions include:
EEPROM Reset: Wiping the internal memory of the waste ink counter. Epson L4150 , L4160, and L4170 Resetter Adjustment
Maintenance: Performing deep cleanings and print head alignments.
Error Logs: Reviewing the history of hardware failures within the machine. How to Use the Resetter
💡 Important: Resetting the software without checking the physical pads can lead to ink leaking onto your desk.
Download and Extract: Obtain the specific Adjustment Program for the L4100 series.
Connection: Connect the printer via USB (Wi-Fi resetting is unstable).

Particular Adjustment Mode: Navigate to "Waste ink pad counter."
Initialize: Check the "Main pad counter" box and click "Initialize."
Power Cycle: Turn the printer off and back on to finalize the reset. Physical Maintenance Requirements
Software resets are only half the battle. To keep the printer healthy:
Clean the Pads: Remove the maintenance box at the rear and wash/dry the sponges.
External Tank: Many high-volume users install an external waste ink bottle to bypass the internal pads entirely. On the next screen, look for the section
