CHAPTER 4 IMAGE FORMATION SYSTEM

8.2 Monitoring the Waste Toner Case

The machine checks the waste toner case in reference to two levels.

The amount of waste toner inside the waste toner case is monitored by the waste toner case full sensor (S2); the sensor is a pair of photosensors (light-emitting unit piece and light-receiving piece). The machine will assume that the waste toner case has become full when waste toner blocks the light between the two photosensors.

The DC controller PCB checks the waste toner case full sensor when the power is tuned

on and at time of delivery; it will assume a “waste toner full warning” after making a total of 100 prints after the waste toner case has become full, thereby indicating the Waste Toner Case Full message on the control panel.

After the message Waste Toner Case Full is displayed in the control panel, the machine will indicate 'E019' in its control panel if the case remains full upon generating about 2000 prints (cumulative).

If the waste toner case is not set, the light-blocking plate will block the light between the photosensors, causing the Waste Toner Case Full message to appear.

The light between the photosensors is not visible to the eye.
