The machine collects waste toner discharged from the 2 types of cleaning units (ITB cleaning unit, drum cleaning units of individual colors) for collection in the

waste toner case.

When the power is turned on or for each print job, the DC controller drives the waste toner transport motor (M12) to rotate the feedscrew inside the waste toner

pipe, thereby moving the waste toner.

The waste toner pipe is connected to the discharge outlet of the cleaning unit. When M12 goes on, the waste toner collecting at the discharge outlets is moved

through the waste toner pipe for collection in the waste toner case.

Waste Toner-Related Error Code:

- E013-0000 (waste toner transport motor fault)

Occurs when an over-current (350 mA or more) has been detected about 0.1 sec after the motor is driven.

- E013-0001 (waste toner transport motor open circuit)

Occurs when an open circuit has been detected about 0.1 sec after the motor is driven.

7.8.2 Detecting the Level of Waste Toner

iR C3380i / iR C3380 / iR C2880i / iR C2880 / iR C3580 / iR C3580i / iR C3080 / iR C3080i

The machine executes the following 2 types of detection to find out the level of waste toner collected inside the waste toner case:

- detection by an optical sensor

- detection with reference to the video count

The DC controller checks the result of these detection mechanisms when the power is turned on, when the front door is opened/closed, and for each print job. If it

finds that the level of waste toner is above a specific value, the DC controller issues to the main controller either of 2 messages (waste toner case full alert, waste

toner case full).

The following shows the relationship between messages and waste toner levels:
