Solución paso a paso

  1. Remove any paper from the feed tray.
  2. Clean the pick rollers thoroughly with a recommended cleaning cloth.
  3. Ensure the side paper guides are adjusted snugly against the paper stack.
  4. Use high-quality paper to test if the feed mechanism resumes working.

Prevención y mantenimiento

Regularly wipe rollers monthly to prevent dust-glazing. Replace your roller kits according to the duty cycle specified by the manufacturer to prevent U002 occurrences.
