Cleaning the Paper Guide Rollers

If you see ink on the back of a printout, you can clean the paper guide rollers to remove any excess ink.
If plain paper isn't effective, you can use Epson Ink Jet Printer Cleaning Sheets (part number S041150)
to clean the rollers. A cleaning sheet will help remove dust from the rollers, which can cause a loss of
traction and prevent paper from feeding properly.
Caution: Remove the instruction sheet attached to the Epson Ink Jet Printer Cleaning Sheets and do not
follow the steps on it; they are not correct for your printer. Do not use the cleaning sheets that come with
certain Epson special papers; they may jam inside your printer.
