When automatically feeding transparencies or back print film, remove each sheet after it is delivered. Do not allow film sheets to stack up in the paper output tray.
Place at least one sheet of plain paper in back of a stack of transparencies or back print film to avoid paper jams and
zmisfeeds.
Let the printed sheets of film dry completely before storing them. The complete drying time required for color printing on Canon's transparencies or back print film is approximately 15 minutes. The complete drying time required for solid black printing on this media is approximately 30 minutes. You may be able to reduce the drying time if you reduce the density setting in your application before printing.
If printing at 720 x 720 dpi in black on back print film appears blurred, switch to 360 x 360 dpi or reduce the density setting in
zyour application.
If printing in black on transparencies is not as crisp as you
3DSHU+DQGOLQJ expected, reduce the density setting in your application.
