1.4.1 Print Modes
The Duplex Assembly has the following two print modes.
• Simplex Mode
The printer prints on one side of the paper only and immediately ejects the sheet into the
tray. Prints made in the simplex mode are called simplex prints.
• Duplex Mode
The printer prints on both sides of the paper and then ejects the sheet into the tray. Prints
made in the duplex mode are called duplex prints.
1.4.2 Duplex Print Processing
There are two types of duplex printing, producing different page sequences: one-sheet batch
and two-sheet batch.
• One-Sheet Batch
The printer prints on both sides of a sheet of paper and then feeds in the next sheet.
• Two-Sheets Batch
The printer prints on the first side of the first sheet of paper, the first side of the second
sheet, the second side of the first sheet, and the second side of the second sheet. It then
repeats the process with the next two sheets.
NOTE: For further details on these two form of duplex printing, see Section 1.2 "Duplex
Sequence" in Chapter 6.
1.4.5 Continuous Printing Speed
The tables below show the calculated maximum speed of the continuous printing at the duplex
mode when /PRDF is used. The actual speed may lower than those indicated value because of
paper feed delay or other reasons Table 1 & Table 2.
