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).
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.
The higher the value, the more
the original is fed towards the
exit side of the machine.
1 step is equal to approxi-
mately 1mm change.
Test copy cannot be made in
05 test mode. Press 09 to
enter normal copy mode and
toggle back to 05 mode to
adjust.
Perform RADF EEPROM
Initialization when EEPROM,
RADF logic PWA or sensors
are replaced.
Adjust the width of the printed
image (front to rear of
machine) to 1:1, so that it is
not stretched or compressed.
When the value is increased
by 1, the width reproduction
ratio is enlarged by approxi-
mately 0.05% step (or 0.1mm/
step). After setting the value,
select LT/A4 paper, then press
the ENERGY SAVER key to
make a test print.
Adjust the width of the copied
image (front to rear) to 1:1 so
that it is not stretched or

is increased by 1, the width
reproduction ratio is enlarged
by approximately 0.05%/step
(or 0.1mm/step). After setting
the value, select LT/A4 paper,
then press the ENERGY
SAVER key to make a test
copy.
