During the printing process and the automatic cleaning cycles it performs, excess ink is collected in an absorbent pad (the waste ink pad or maintenance box). The printer uses a counter to estimate how full this pad is. Once the counter reaches a certain threshold, the printer locks itself down to prevent potential ink leakage, which could damage the device or your workspace.
Resetting the digital counter via software tricks the printer into thinking it is brand new. However, it does not magically clean the physical waste ink pads. adjustment program epson l3150
