Epson “ink pad is at the end of its service life”: causes and how to reset the counter

Updated 2026-06-27 · VNIT — 10 years repairing printers & laptops · Nationwide support

Your Epson printer was working fine and now it is flashing two lights, won't print, and the software says “A printer's ink pad is at the end of its service life” or “Service Required” / error E-11? This is the waste ink pad counter — very common on EcoTank L-series printers. This guide explains what it really is, the three ways to reset it, and an important warning few shops mention honestly: a reset is not the same as emptying the waste ink.

What “ink pad end of service life” really means

Every Epson inkjet has a waste ink pad (an absorbent sponge) that catches the surplus ink produced during initial ink charging, head cleaning and borderless printing. The firmware keeps an estimated count of how much ink has been pushed into the pad over time. When that number passes a preset threshold, the printer locks printing and reports the error so ink does not overflow inside the machine.

The wording depends on where it shows: on the LED panel it is “two lights blinking”; in the Windows software it is “ink pad is at the end of its service life” or “Service Required”; on models with a screen (ET-series) it is error code E-11 / E-12. They all share one root cause: the waste ink pad counter is full.

The software counter is NOT the physical pad (the key point)

This is what decides whether the problem is handled correctly. There are two different things:

• The counter — a number in firmware. A reset only sets that number back to 0%.
• The physical pad — the real sponge inside, soaked with ink. A reset does not remove any ink from it.

Epson deliberately sets the alarm threshold early, with a safety margin (there is no sensor measuring the real sponge). So the first time the error appears the pad is usually only partly saturated — resetting to keep printing is generally safe. But if you keep resetting again and again without dealing with the pad, ink keeps building up until it can overflow onto the base of the printer and the mainboard.

The 3 ways to reset the waste ink pad counter

1. Epson's one-time reset utility — some models have an official “Ink Pad Reset Utility” that allows a single reset so you can print temporarily, with maintenance still recommended.
2. WIC Reset Utility — free to download and free to read the counter status, but each reset to 0% needs a paid Reset Key (one-time use). Note: the free trial key only lowers the counter to 80%, once per machine — that is not a real reset.
3. Adjustment Program (AdjProg) — model-specific service software that runs offline and takes the counter straight to 0%. Many older models can run AdjProg, but you need the exact build for that model. Some newer models have no public AdjProg — doing it yourself then means WIC + key; but for common models like L3210, L1210, L3250, L3260, VNIT resets them directly, so you do not have to buy a WIC key.

⚠️ Be careful: cracked AdjProg / “100% free reset” tools are both copyright infringement (Epson and WIC now enforce licensing heavily) and frequently laced with malware — risking data loss and a damaged printer. VNIT uses its own licensed reset tool, so it is safe and legal.

A reset does NOT drain the ink — when must the pad be cleaned/replaced?

Clean or replace the pad (not just reset) when you see: ink leaking onto the desk, smudges on the back of the page, wetness around the wiper/parking station, or the error returning quickly a few days after a reset. There are two pad types:

• Fixed pads (L3110/L3150/L3210/L1110… and most older machines): located in the base — you must open the body to clean/replace them, or fit an external waste ink tank.
• Removable maintenance boxes (L4150/L4160/L6160…, newer ET/WF series): pulled out and replaced as a consumable (C9344/C9345/T04D1). After replacing the box you still have to reset the counter.

Does a reset change print quality?

A reset only sets the waste ink pad counter back to 0% so the printer unlocks and prints again — it does not improve print quality. However the printer printed before the reset, it will print exactly the same afterwards, because print quality depends on the print head (nozzles), not on the counter.

⚠️ If a test print shows missing lines, white streaks or wrong colours, that is a print-head problem, not a counter problem — it needs head cleaning/unclogging, which a counter reset cannot fix.

By model: which method does your printer use?

See the full Epson reset table by model, or send your model on Zalo/WhatsApp and VNIT will check it for free.

Cost & remote Epson reset service (nationwide)

A correct reset needs the right tool for each model and avoids common mistakes (buying the wrong key, downloading a fake file, a faulty key you have to re-buy). For speed and safety, let VNIT reset it remotely via UltraViewer/TeamViewer anywhere in Vietnam: VNIT has its own reset tool, so almost every Epson (including L3210, L1210, L3250, L3260…) is reset directly From 150,000₫ — you do not buy a WIC key; only the hard-locked C9345 box needs replacement instead. We check and advise on the pad at the same time, and you pay only after the printer prints again.
