15.3 Operation
15.3.1 Synchronizing Roller control
• A loop is formed in the paper between the Transport Roller and Synchronizing Roller dur-
ing the paper transportation to correct skewed paper feeding. The amount of the paper
loop can be adjusted using "Loop Adjust" of the Tech. Rep. mode. The ON timing of the
Intermediate Transport Motor as the motor is restarted is varied by changing this setting.
(This adjustment should be made when a tilted image is printed due to paper skew or a
Z-folded paper misfeed occurs at the Synchronizing Roller.)
• "Top Margin" available from the Tech. Rep. mode should be adjusted based on the image
writing start timing. (This adjustment should be made if the image on the copy deviates in
the FD direction.)
