After a long, continuous print job with NCR paper, you may find that on the next job with normal paper the back sides will be stained and dirty.

Cause

Particles are clinging to the paper transfer roller.

Solution

  1. Open the front doors, and then pull out the drawer.
  2. While rotating the front gear with your left hand as shown, clean the transfer roller with a dry, clean cloth.
  3. If this does not solve the problem, replace the paper transfer roller.
