Before attempting a reset, ensure your ink tanks have enough ink. Some reset procedures require the printer to run a verification cycle, which consumes ink.
A: Technically, indefinitely. However, the sponge inside has a finite life. After 3-4 resets, you must replace or wash the physical pad, or the ink will spill out.
Epson engineers program a "tipping point" into the firmware. This is a theoretical limit of ink volume that the pad can hold before leakage risks become statistically probable. The counter does not measure moisture; it estimates volume based on the duration of cleaning cycles.
