The Epson “waste ink pad” error indicates the printer’s internal absorbent pads (or a counter tracking ink waste) are full or the printer believes they are. Resetting without servicing can restore function temporarily but may risk ink overflow and ink damage; proper fixes are replacing/cleaning the pads or having the printer serviced.
These are usually located in a small compartment at the back or bottom of the printer, secured by a single screw. how to reset epson waste ink pad error
