Just wondering if anyone has any advice for lining up letter sized sheets in the Epson 9800? Often, when I load a letter sheet, the print will come out slightly crooked. This isn't a problem on bigger sheets, as I can feed them through to the lower line to line them up, but the 9800 won't let you do this with letter sheets; top load only. Anybody figure out a sure fire way to line up small sheets with these printers?
