My printer, An Epson Stylist Photo R2400, has been a fantastic work horse for printing amazing exhibition-quality prints. Due to an extended move, it has not been operated for some time, and got some dust inside. The result was, the paper would feed, but the printer could not see it, and thus, assumed a miss-feed. I contacted Epson for help. I figured it was probably just a dirty sensor, but where was it, and how could I find it? The printer, of course, is WAY WAY past its warranty. Well, they suggested I use this "printer cleaning sheet."
I was dubious, but what the heck, buying a new printer would be $600 or more. I purchased this item, and loaded it into the printer. It loaded properly. What? And ejected properly. No blinking red lights. And no visible dirt on the sticky sheet, either. What the...? It can't be fixed already, can it? Sure enough, everything is now working fine! The repair was cheap and so easy it took me by surprise.
So, if you are having trouble with dirty sensors, this is one amazing simple solution!
