Drive force diagram of the MFP is shown below.
Overview of operation modes
There are four operation modes that are executed by the MFP. The respective operation
modes are executed in accordance with the instructions given by the connected equipment
to implement the print operation.
Name of the operation modes, the overview of the operation and the corresponding print
modes are shown in the following table.

Overview of the operation
Supporting print modes
[1] Normal direction feed
paper/Unload paper
Document is fed and
scanned. Upon completion
of scan, document is
unloaded as it is.
Single-sided document => Single-sided print
Single-sided document => Both-sided print
(This operation is performed in both cases
when documents of same width and
different width are used.)
[2] Normal direction feed
paper/ Inverted unload
paper
Document is fed and
scanned. Upon completion
of scan, document is
inverted and unloaded.
Both-sided document => Both-sided print
Both-sided document => single-sided print
(This operation is performed in both cases
when documents of same width and
different width are used.)
Normal direction feed paper and unload paper (single-sided document => single-
sided print) operation
Outline of document flow is shown below.
Supplement: When a single-sided document is selected, this operation is performed
regardless of the same size mixed documents or different sizes mixed
documents.
