2-Sided Copying
2-Sided Copying
This mode enables you to make two-sided copies from one-sided or two-sided originals, or
make one-sided copies from two-sided originals. This enables you to cut print costs in half
when copying in large quantities.
The default setting is <Off>.
When you use the feeder to make two-sided copies from two-sided originals or one-sided copies from two-sided
originals, the original size must be LTR, LGL, FLSC, or A4.
For the paper size that can be used for the 2-sided copying, see the following:
e-Manual > “Print” > “Printer Settings from the Machine” > “Settings Menu” > “2-Sided”
(The same paper size can be used for the 2-sided copying and 2-sided printing.)
2-Sided modes cannot be used with the ID Card Copy mode. –
