Epson L4150 L4160 L4170 Resetter Adjustment Program May 2026

Inkjet printers from Epson’s EcoTank line, including the L4150, L4160, and L4170, are celebrated for their high page yields and low running costs. However, like all inkjet printers, they rely on a maintenance box (also called a waste ink pad or absorbent sponge) to collect excess ink from cleaning cycles and borderless printing. Over time, this pad fills up. When the printer’s internal counter reaches a preset limit, it locks down and displays a “Service Required” or “Ink Pad Counter” error. Resolving this requires a Resetter Adjustment Program—specialized software that resets the counter and allows the printer to function again.

After resetting your printer, reduce how often the waste pad fills up:

Resetting the waste ink counter without replacing the physical waste ink pads can lead to ink overflow, causing permanent damage to the printer, contamination of work surfaces, and voiding of manufacturer warranties. This procedure is intended for trained service personnel or advanced users who accept all associated risks.

The Epson L4150/L4160/L4170 Resetter Adjustment Program is a necessary service utility to recover printers locked due to waste ink counter overflow. When used responsibly—including physical pad replacement—it extends printer life significantly. Misuse without pad replacement leads to irreversible ink damage. Always combine software reset with hardware maintenance.

Step 1: Prepare the Printer Turn off the printer. Remove the power cord from the back of the printer. Press the power button for 5 seconds to drain residual electricity. Wait 30 seconds. Plug it back in and turn it on. Ensure paper is loaded.

Step 2: Enter "Service Mode" Unlike normal printers, the L4150 series requires a button sequence to enter Service Mode so the resetter can talk to it.

The screen will usually go blank or show a specific code (like "S" mode). Epson L4150 L4160 L4170 Resetter Adjustment Program

Ethically, the resetter enables reuse of a printer that would otherwise become e‑waste prematurely. Many DIY communities support it as a repair tool, not a piracy tool. However, repeatedly resetting without maintenance is irresponsible and can permanently damage the printhead or ink system.
