Fred/Terry,
I had a paper feed issue with my R1800 (still do actually) and the epson support recommended the Platen Cleaning sheets. Here is the link
http://epson.custhelp.com/app/answers/detail/a_id/12552 . If the link doesn't work, the product code is S041150. It didn't solve my problem though. My R1800 (which I love also) will double/ghost print as well but mine sounds more like the gears jumping teeth when printing, happens about 80% of the time now. I've tried different papers, changed to the thick paper setting which helped initially, ran through the service manual and tried things I could do without the epson diagnostic tools (o'scope, etc.).
Thanks,
Dave
