  2. Manually test if the toner auger gear on the cartridge rotates freely.
  3. Clean the entry port where toner feeds into the developer.
  4. Reinstall and reset the printer.

Prevention and Maintenance

Always use original supplies to ensure the toner viscosity is consistent with Konica Minolta's supply motor specs.
