It resets the electronic counter on the T04D1 chip back to zero percent.
If the chip counter has dropped below 15% or hit absolute zero, some cheap resetters fail to recognize it. It is best to reset the chip when the printer warns you it is "low," rather than completely "empty."
An electronic chip on the maintenance box communicates directly with the printer. The printer does not physically weigh or measure the liquid ink in the box. Instead, it estimates ink consumption using an internal counter. Once this counter reaches 100%, the chip signals the printer to lock down. This safety feature prevents excess ink from overflowing, leaking onto your desk, or damaging internal circuitry. What is a Maintenance Box Resetter?
This is the most straightforward hardware method. maintenance box resetter for epson l6170
: The resetter features specialized metal pins that must align precisely with the contact points on the T04D1 chip.
: Locate the panel on the rear or side of your printer (usually secured by a single screw), slide it off, and pull the T04D1 box out.

A software utility called is popular among Epson printer users for resetting waste‑ink counters on many models.

However, WICReset is not free – you usually need to purchase a reset key after the software diagnoses your printer.
However, using a resetter requires a degree of caution. Resetting the chip does not physically remove the liquid ink trapped inside the box. If a user resets the chip multiple times without cleaning or replacing the internal pads, the box will eventually overflow, potentially causing permanent damage to the printer’s internal circuitry or staining the workspace. Therefore, the most responsible way to use a maintenance box resetter is in conjunction with manual pad maintenance.
