Chapter 2 Operation Description

 
This mechanism prints image data from the control board on the paper by electro-photographic process.

The Figure 2-4 shows the layout of the electro-photographic process mechanism.

(1) Image drum unit

The image drum unit consists of a sensitive drum, a charger, and a developer. The unit forms a toner 
image on the sensitive drum, using a electrostatic latent image formed by the LED head.

(2) Hopping motor

This motor is a pulse motor of 48 steps/rotation that is two-phase excited by the signal from the control 
board. It drives the hopping roller of the first tray and the front feed roller via two one-way clutches 
according to the direction of rotation.

(3) Motor-Main

This motor is a pulse motor of 72 steps/rotation that is two-phase excited by the signal from the control 
board and is the main motor of this mechanism.

(4) Clutch (for Roller-Regist)

(5) Clutch (for Feed Roller)
