correct size.
Do one of the following:
Put the same size of paper in the paper tray
that is selected in the printer driver, and
then press Start.
In the printer driver select the size of paper
that you loaded in the indicated paper tray.

printer driver is too small for the
machine to deliver it to the

Open the back cover (back output tray) to let
the printed paper out on the face-up output tray
and then press Retry.

replacement toner cartridge will be available
when the Touchscreen displays Replace
Toner.
