I have a brand new xerox workcentre 6605 that, as the title suggests, is wrinkling envelopes out of the bypass tray. I tried all of the easy stuff like flattening envelopes before loading them, tried different brands of envelopes, different paper type settings just for kicks. The envelopes come out wrinkled down the sides and bottom every time. Does anyone have any suggestions or solutions to this issue?
