I found it impossible to change the ink waste pad on my Epson: talked to Mr Serviceman who said yes I can do it but it will cost more than a new printer.
Slight Drift, but I had endless problems with Epson nozzles clogging up in the summer if I didn't use the printer for 7 - 10 days. Wrote to the Spanish Epson dealer who passed my letter to the factory who wrote back saying little. All I could do was run the "clean nozzles" routine every time I wanted to use it. Expensive in ink !
So when the ink waste pad incident came up I junked the Epson (couldn't even give it away for spares to friends with Epsons) and bought an HP: nozzles/ink has not clogged once in three years.
