Roller speed adjustment
Every paper transport roller installed in the machine is controlled of the rotation speed according to the
basis weight (thickness) of the paper, to support wide variety of media and prevent image quality
problems.
While the transport speed at the surface of the paper can roughly be determined by the rotation speed
of the roller and the radius of the roller added with thickness of the paper, the speed at the paper
surface becomes much faster with bulky stocks, and causes deviation in the image magnification ratio.
Also, the media will slacken/stretch, if the rollers expand/contract due to the change in environmental
conditions, resulting in image quality issues such as banding and color inconsistency.
Printed images may also get scratched by the guide plates in the paper path.
