BASIC DUPLEX FEED OPERATION

To improve the productivity of duplex copying, a non-stacking style duplex
mechanism is adopted. This type of mechanism allows more than one page to be
processed at once, in a process called 'interleaving'. Examples of this are given
below.
For paper lengths up to A4/Letter LEF, the top duplex speed is possible, with the
duplex unit processing four sheets of copy paper at the same time.
For paper longer than this, the duplex tray can process two sheets of copy paper at
once.
For a single-set duplex copy job, the duplex unit stores only one sheet of copy
paper. For a multi-set duplex job, the job is stored first, then the first set is made
using interleaving.
Length up to A4/Letter LEF
The duplex unit can process four sheets of copy paper
Example: A 14-page copy. The large numbers in the illustration show the order of
pages. The small numbers in circles show the order of sheets of copy
paper (if shaded, this indicates the second side).
