What to do if Ricoh PE-P1 shows Waste Toner Bottle Set Error?
- C
  Caitlin PeckJul 31, 2025
  If your Ricoh Copier displays a Waste Toner Bottle Set Error, it could be due to several reasons: the waste toner bottle might not be properly installed, the harness of the waste toner bottle set sensor could be disconnected or defective, or the waste toner bottle set sensor itself might be defective. To resolve this, first install the waste toner bottle correctly. If the problem persists, check or replace the harness of the waste toner bottle set sensor.
