It can’t clean if the cleaner is dirty

This is the part of an epson printer that is supposed to clean the bottom of the print head where the injet nozzles are, how do you expect it to clean the print head if its this clogged up with ink and other debris.the best way to clean this up is use some print head cleaning solution on a paper towel or tissue, making sure to clean carefully. If in doubt please contact a printer engineer.

As a note if a epson printer is in this kind of condition it way be worth your while getting the printer serviced as it may well be reaching the head cleaning counter limit and filling its waste ink pads.
