1. What Is It? The Epson L405 is a popular multi-function ink tank printer (print, scan, copy). Like many modern Epson printers, it uses a waste ink counter (also called protection counter or pad counter). This counter tracks how much ink has been flushed into the internal waste ink pad during cleaning cycles.

Once the counter reaches a factory-set limit (usually around 15,000–20,000 pages), the printer stops working and displays an error message: “Service required. Parts inside your printer are at the end of their service life.” (Error code: 0x69, 0x9A, etc.)

resets this waste ink counter to zero, allowing the printer to function again without physically replacing the waste ink pad first. ⚠️ Important: Resetting without replacing or cleaning the waste pad can cause ink overflow, damaging the printer internally. 2. Why Is Resetter Software Needed? Epson designs the counter to prevent ink from leaking out of the printer. In many countries, replacing the waste ink pad requires a costly authorized service center visit. Resetter software offers a temporary (or permanent, if you manage the pad) DIY fix.
