1

Copy lamp (Xenon lamp)

Generate photo energy to scan documents.

 

 

 

2

Reflector (Converging plate)

Collects light emitted from the copy lamp and radiate the document.

 

 

 

3

No. 1 mirror

Refracts the reflection light from the document to No. 2 mirror.

 

 

 

4

No. 2 mirror

Refracts the reflection light from No. 1 mirror.

 

 

 

5

No. 3 mirror

Refracts the reflection light from No. 2 mirror.

 

 

 

6

Lens

Converges reflected light from the document to form images on the CCD element.

 

 

 

7

No. 2/3 mirror unit

Includes No. 2/3 mirror. Driven in synchronization with the copy lamp unit.

 

 

 

8

Copy lamp unit

Includes the copy lamp, the reflector, and No. 1 mirror. Driven in synchronization with No. 2/3

 

 

mirror unit by the mirror motor.

 

 

 

9

CCD PWB

Reflected light (image) formed on the CCD is converted into electrical signals (analog signals)

 

 

then into digital signals and sent to the MCU.

 

 

 

10

Mirror motor

Drives the copy lamp unit and No. 2/3 mirror unit according to the scanning speed.

 

 

 

11

MHPS (Mirror home position sensor)

Detects the home position of No. 2/3 mirror unit.

 

 

 

12

Reference white plate

Reference white sheet for scanning documents. The reference line of magnification ratio

 

 

adjustment during SIM is also drawn.

 

 

 

13

OC glass

Glass table to put a document on it.

 

 

 

The light from the light source (Xenon lamp) is reflected by a document and passed through three mirrors and reduction lenses to the CCD element (image sensor) where images are formed. This system is known as the reduction image sensor system. Photo energy on the CCD element is converted into electrical signals (analog signals). (Photo-electric conversion). The output signals (analog signals) are converted into digital signals (A/D conversion) and passed to the MCU (main control/image process section). The resolution at that time is 400dpi. The mirror unit in the scanner section is driven by the mirror motor. The MHPS is provided to detect the home position of the copy lamp unit.

Toner on the OPC drum is transferred

 

 

to the print paper by the potential

 

 

difference.

 

 

 

5

Resist roller

Makes synchronization between the

 

 

paper and the print image.

 

 

 

6

MG roller

Magnetic brush is formed by

 

 

developer to put toner on the OPC

 

 

drum.

 

 

 

7

(Laser beam)

Forms images on the OPC drum.
