[Function]

Enter the correction value and press [START] key to save the entered correction value. (Correction
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 opera-
tion 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 output
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 test command 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 test command.
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.
