Only perform this procedure if absolutely necessary. IIT lead registration affects the precision
of document size detection.
NOTE: For a description of the print/copy orientation definitions, refer to GP 31 Print/Copy Ori-
entation Definitions.
1. Ensure that the IOT lead edge registration is correct. Refer to dC126 System Registra-
tion.
2. Make two, 100% copies of test pattern 82E8220 from the document glass.

tion:
• Increase the value to move the image towards the trail edge of the copy.
• Decrease the value to move the image towards the lead edge of the copy.
NOTE: An increment of 1 in NVM = 0.34mm (0.014inch).
