2-sided printing methods
A. Operations in 2-sided printing with a single sheet of paper resident in the system
Operation 1
• The first sheet of paper is taken up and fed in from the
main body drawer and the main body starts the first print
cycle to produce the print image of the second page of the
original.
Operation 2
• Immediately before the 1-sided print leaves the paper exit/
switch back roller, the direction of rotation of the paper exit
roller is reversed and the 1-sided print is transported
toward and into the duplex unit.
Operation 3
• While passing through the duplex section, the 1-sided print
stops temporarily and is subject to the second print cycle.
