Epson printer maintenance box. (See under the compatibility table)
This is the tank where the printer leaves the ink residue after cleaning. Inside there are some felts to absorb the waste ink. When the maintenance box reaches its end of life, the printer will be blocked, to start it up again, the counter must be reset using the WIC RESET system and subsequently replaced with a new one.
The change process is very simple, the user himself can do it easily and quickly in less than 2 minutes.
