adjustment in duplex copy
[Function]
Used to adjust document scan off-center adjustment.
The adjustment modes can be selected by pressing [Exposure mode selector] key (or [
[ ] key for the AL-2050/2060). (Adjustment range: 1 – 99, Default: 50)
When the adjustment value is increased, the print result is shifted to left.

* When paper is discharged, the shifter is operated.
[Operation]
The operation is similar to simulation 46-01.
[Function]
When this simulation is executed, the current set correction value is displayed.
Enter the correction value and press [START] key to save the entered correction value. (Correc-
tion value range; 1 – 99, Default: 50)
For S-D mode front surface print and print of even paged in D-S mode, reverse memory copy
operation is performed from the rear edge of documents.
When, therefore, the print position adjustment of output images is required, adjust as follows:
In the reverse memory coping, when the document scan is made in the arrow direction, the out-
put image is printed from the rear edge of scan image.
When, therefore, the print lead edge is shifted, set the reference chart so that the reference
position is on the rear edge, and use this simulation to adjust the set value so that the print lead
edge is matched.
Since printing is made from the image data most lately stored in memory to the lead edge data
from the print start position, the image lead edge adjustment is made by changing the end data
position stored in memory by the set value of this simulation.
Since it is performed by changing the scan end position, the image position adjustment is made
by changing the scan end position and the end data stored in memory.
The adjustment modes can be selected by pressing [Exposure mode selector] key (or [
[ ] key for the AL-2050/2060)

* The initial value of duplex setting is "1to2/Long Edge" for the duplex model, or "2to1" for the
simplex model.
∗ When paper is discharged, the shifter is operated.
[Operation]
The operation is similar to simulation 46-01.
