Epson L810 series, L850 series. A printer's ink pad is at the end of its service life. How to fix it.

This error occurs when the ink pad's life has expired. Ink pad is a reservoir for waste ink. So every time the printer does cleaning, it will produce waste ink. This ink waste is collected in the ink pad. There are two ink pads on the Epson L810, L850, namely the Main ink pad and the Platen ink pad.

Main ink pad

Platen ink pad

The main ink pad is the main container for waste ink generated from the print head cleaning process, while the Platen ink pad is a container for ink splashes when printing on the edge of the paper. Because there are two ink pads installed on the printer, when the ink pad is at the end of its service life an error occurs, what is meant here is Main ink pad is at the end of its service life. When this error occurs, we recommend replacing the Main ink pad with a new one, but if the Main ink pad is not available in the market, the alternative solution is to clean the Main ink pad and use it again.
