In Connect Copy mode, both the main and sub machines must feed paper that is the same size, type, and orientation. To get the best results, the paper settings should be the same on both machines.
When two or more trays hold the desired paper size, the paper tray will be selected according to the [Paper Tray Priority: Copier] settings made on the respective machine. For details, see "System Settings", Connecting the Machine/ System Settings.
If the sub-machine has a paper tray containing paper of the same size but set in a different orientation, when the current tray runs out of paper, the sub-machine automatically switches to the tray containing paper of the same size and rotates the print images in order to make copies (When [Auto Tray Switching] is set to [With Image Rotation]).
