, the adjustment program does not physically clean or replace the waste ink pads. It merely resets the internal counter that tracks their saturation level. The actual accumulated ink remains inside the pads. This means that resetting the counter without replacing the pads is only a temporary solution. If the pads are truly full, there is a genuine risk of ink leakage and internal printer damage over time. For this reason, it is strongly recommended to physically inspect or replace the waste ink pads when performing a reset.

This can lead to ink leaking onto desk surfaces or into the bottom circuitry of the printer. When resetting the internal platen counters via software, it is highly recommended to physically inspect or replace the physical absorber pads underneath the printing mechanism if you routinely perform high-volume borderless printing.
