Duplex Printing Mode
The printing operation flow in duplex printing mode is as follows. Initially, the first
sheet is fed and page 2 of the document is printed on one side of the sheet. The first
printed sheet is temporarily transferred to the duplexer. Then the printer feeds the
second sheet on which page 4 is printed on one side. After page 4 has printed, the
first sheet held in the duplexer is again sent to the printer's transfer unit for printing
of page 1. This completes printing of the first sheet and this is output. Following
this and while the second sheet, on which page 4 has been printed on one side, is
retained on standby in the duplexer, the printer feeds the third sheet and prints page
6 on this sheet. The operation is now repeated as described above to perform the
duplex printing.
