The path between the sub hopper and the developing
assembly is clogged with toner.
1.Check the rotation of hopper motor gear. (If rotating, false
detection by the sensor is doubted. Feed the toner to the
developing unit in service mode: CLEAR>ENGIN>TNRINST.)
2.Replace the Developing Assembly Toner Sensor (TS1).
3.Replace the Sub Hopper Toner Sensor (TS2).
4.Replace the DC Controller PCB (PCB4).
