The Transfer Unit consists of the Belt, ADC Sensor, ADC Solenoid, and ADC
Pad.

Position of ADC Sensor
Belt
The Belt feeds the paper toward the direction of the Fuser.
ADC Sensor
The ADC Sensor detects the toner patches on the Belt and converts them
to voltage value. The voltage value is used to control density of toner.
ADC Solenoid
To activate the ADC Pad, turn On the ADC Solenoid for a fixed time
before the ADC Sensor starts reading the toner patches. When turned
On, the ADC Solenoid activates the ADC Pad, which cleans
contamination on the ADC Sensor surface.
