SP1-xxx Feed
To prevent such distortion, use this SP to decrease the speed of the fusing
motor. While this lowers the line speed slightly, it also keeps the correct
amount of tension on the paper between the fusing unit and registration roller
to prevent skewing and image distortion.
Important
There are two adjustments for each feed source and paper width: (1) "Chg
Timing" and (2) "Chg%".
Always do the "Chg Timing" adjustment before doing the "%Chg
adjustment".
The "Chg Timing" adjustment sets the length of paper to feed before the
speed reduction rate ("Chg%) takes effect.
The "Chg%" adjustment sets the rate of speed reduction between the main
motor and fusing motor.
