1. Check rotation of the Hopper Motor Gear. (If it is rotating, the
sensor may not be detecting correctly. In that case, execute Service
Mode>CLEAR>ENGIN>TNRINST to supply toner to the Developing
Assembly.)
2. Replace the Developing Assembly Toner Sensor (TS2).
3. Replace the Hopper Toner Sensor (TS1).
4. Replace the DC Controller PCB (PCB1)
