Copier 128 0-255 Adjust the length of the copy
image to 1:1 so that it is not
stretched or compressed. Use
a millimeter scale and ledger/
A3 paper to adjust. Increasing
the value decreases the length
0.05% step(or 0.1mm/step).
All 8 0-15 The higher the value, the more
the original is fed towards the
paper feed side of the
machine.
1 step is equal to approxi-
mately 1mm change.
Test copy can be made in 05
test mode.
