(7)Discharge LED

Discharging is a process to decrease or eliminate the static electricity on the drum surface.

The electrical resistance of the photosensitive layer is decreased by the light irradiation, and the residual charge on the drum surface is neutralized and eliminated (cleaned). The electrical poten- tial of the drum surface is fixed to a certain amount before the drum is charged (The pre-exposure effect).

(8)Toner bag

The residual toner scraped off the drum surface by the cleaning blade is disposed in this bag.

(9)Developer unit cooling fan-1 / Developer unit cooling fan-2 / Middle fan

The developer unit cooling fans-1 and -2, which work to cool down the inside of the equipment, absorb the air from the back of the equipment. The middle fan discharges the air around the de- veloper unit.

(10)Drum thermistor

The electrical charge amount of drum surface varies depending on the drum surface temperature. Therefore, this thermistor detects the drum surface temperature to control to maintain the charge amount at a certain level.

Additionally, the exhaust fan and developer unit cooling fans-1 and -2 change their rotation speed according to the temperature detected by the drum thermistor when the equipment is in ready status or scanning the image.

(11)High-voltage transformer

This is board to generate the output control voltage of the main charger, transfer charger, separa- tion charger and developer bias.

(12)Temperature/Humidity sensor

This sensor detects the temperature and humidity inside of the equipment since the auto-toner output, main charger grid, developer bias and laser output are affected by environmental ele- ments such as temperature or humidity.
