Theory of Operation
Transfer Unit
The Transfer Unit consists of the Belt, ADC Sensor, ADC Solenoid, ADC Pad,
and ESA Roller.
■ Belt
The Belt feeds the paper toward the direction of the Fuser.
■ ADC (CTD) Sensor
The ADC Sensor detects the toner patches on the Belt and converts them
to voltage value. The voltage value is used to control the 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.
■ ESA Roller
The ESA Roller discharges a positive voltage to the paper. Toner transfer
efficiency is raised by applying a positive charge to the paper.
