Paper Fails to Feed: Worn Rollers
Loss of Friction on Roller Surfaces
Paper with a high ash content (calcium carbonate) can cause paper feed jams in the paper feed units of
the main machine and LCIT RT5130 or LCIT RT5110. In the photo below, [A] shows normal paper fibers
and [B] shows paper fibers contaminated by extremely fine calcium carbonate particles.
These particles are extremely small and easily transferred from the paper to roller surfaces. This
causes the roller surfaces to become slick so they no longer have enough friction to grip the paper for
efficient paper feeding.
Signs of this problem are:
 Paper fails to feed and starts causing frequent jams at the 50K service life of the rollers
 Rollers appear smooth and have not reached the end of service life
 Paper dust appears powdery, not grainy
