Resetter Epson L3110: Fix "Service Required" & Alternating Lights
The Epson EcoTank L3110 is one of the world's most ubiquitous all-in-one desktop tank printers, celebrated for its integrated forward-facing ink reservoirs, spill-free refilling, and low operating costs. But when your machine abruptly halts printing with alternating flashing red indicators and your screen alerts “Service Required: The printer's ink pad is at the end of its service life,” your workflow is completely frozen. Fortunately, your hardware is intact. The printer has merely reached a pre-programmed software safety quota. Here is the verified diagnostic guide and official adjustment utility to unlock your L3110 in under five minutes.
Integrated Tank Design
Compact front-facing reservoir chassis engineered for dense office documents and school assignments.
Digital Protection Lock
Motherboard firmware calculates purge cycles and triggers a total lockout when internal counter registers hit 100%.
5-Minute Direct Reset
Communicates directly over USB to flash EEPROM memory back to 0% without opening chassis panels.
Understanding the "Waste Ink Pad" Issue
Underneath the carriage mechanism inside your Epson L3110 sits a porous felt sponge assembly tasked with collecting excess ink expelled during initial priming, borderless page alignments, and periodic printhead cleaning purges.
Because compact desktop inkjets do not feature physical liquid level sensors, Epson's motherboard relies on an internal counter stored in EEPROM memory. Once this calculated tally reaches 100%, the firmware halts the printer immediately to prevent ink from overflowing onto your workspace.

To clear the firmware lock, we use the official Epson Adjustment Program (AdjProg). This specialized service software allows technicians to read, test, and re-initialize internal logic board registers.

Step-by-Step: How to Reset the Waste Ink Counter
Follow these sequential steps precisely on a Windows computer connected directly to the printer via a USB cable:
Firmware adjustments cannot run over wireless networks. Plug the printer directly into your PC or laptop using a standard USB cable (preferably a USB 2.0 port rather than high-speed USB 3.0 to prevent handshake latency).
Adjustment utilities modify system registers and direct USB channels, which Windows Defender or Chrome routinely flags as a "False Positive." Pause real-time protection for 10 minutes. Right-click the downloaded ZIP file and select Extract All.
Open the extracted folder, right-click on AdjProg.exe, and choose Run as Administrator. Click the Select button at the top right, set Model Name to L3110, and select the specific USB port labeled USB001 (L3110 Series) rather than Auto Selection.
On the main utility interface, click the rectangular button labeled Particular adjustment mode on the right to open the engineering diagnostic options.
Scroll down through the maintenance category list, highlight Waste ink pad counter, and click OK.
Tick the checkbox for Main pad counter and click Check (the counter value will reveal 100% saturation). Tick the Main pad counter checkbox again, and click Initialize. Confirm the prompt with OK.
A pop-up prompt will read “Please turn off the printer.” Press the physical power button on your L3110. Wait until all indicator lights are dark, click OK on your PC screen, and turn the printer back ON.
Troubleshooting Common Reset Errors
If the reset utility encounters an error during communication, apply these verified solutions:
Indicates the software cannot establish two-way communication with the printer logic board. Restart the Print Spooler service in Windows Task Manager, remove duplicate offline printer entries in Control Panel, and switch the cable to another USB port.
This occurs when launching AdjProg.exe from within the compressed preview window. Ensure the ZIP archive is fully extracted to a desktop folder before executing.
Hardware Safety & Maintenance Notice
Your solid green power indicator should now be restored, the alternating red light sequence will cease, and your Epson L3110 is ready for active daily printing.
Remember that resetting re-initializes digital EEPROM memory while physical ink remains stored in the felt pads. If you repeat this reset multiple times over years of heavy operation without replacing the pads, liquid ink may eventually leak into the printer base. Schedule a physical pad replacement or install an external waste tube for heavy-volume workflows.
