Cause

This issue can be caused by many things, including:

  • Misaligned feeder side guides. The guides keep insert material straight as it travels through the system. Over time, the guides may shift and impede insertion.
  • Poor material condition.
  • Poor roller condition. Toner build-up or worn edges can diminish the roller's ability to grasp or drive the material correctly.
