Solutions

Quick Diagnostic

If the bizhub 350 does not lift the paper from the tray and shows C0900, confirm the movement problem is isolated to that specific module.

Step-by-Step Solution

  1. Turn off the printer.
  2. Remove the main paper tray and check for any wrinkled paper.
  3. Verify the feed rollers spin freely.
  4. Power on; if the error repeats, the tray motor may be physically blocked.

Prevention and Maintenance

Do not exceed tray capacity, and fan the paper stack before loading to reduce frictional resistance for the motor.

When to Call a Technician

C0900 is a mechanical failure. If the tray fails to lift even after clearing the paper, professional intervention is needed to repair the lift motor or gears.
