Waste Ink Counter

Waste Ink Counter

Epson inkjet printers have inside a part of sponge for absorbing and collecting waste inks. It is called waste ink pad.
Ink is collected by waste ink pads during the initial setup of the product, during cleaning cycles and when printing borderless photographs. While printhead cleaning process ink flush through printhead to waste ink pad.
So one time it can be overflowed because  it could not absorb ink anymore then the ink will leak from the bottom of the printer.
The printer counts how much ink flow to waste ink pad and stores this number into printer’s memory.
This number is called Protection Counter or Waste Ink Counter. 

So to prevent ink leaking outside the printer the waste ink counter may be overflowed and printer will stop.
To get printer working again - You have to RESET the Waste Ink Counter.
