Name

Function/system

[1]

G2 Lens/Y, M, C, K

• Condenses the incident laser light and irradiates the K Photo

Conductor or Return Mirror/2nd of each color with the con-
densed laser light.

[2]

SOS Lens

• Condenses the incident laser light/K onto the SOS Sensor.

[3]

SOS Sensor

• Generates an SOS signal based on the incident laser light/K.

[4]

Separation Mirror

• Reflects the laser light/K, the condensing angle of which has

been corrected by the G1 Lens, onto the G2 Lens/K.

• Reflects the laser light/K (for SOS), the condensing angle of

which has been corrected by the G1 Lens, onto the SOS Lens.

[5]

Return Mirror/1st

• Reflects the laser light/Y, M, C condensed by the G1 Lens onto

the G2 Lens/Y, M, C.

[6]

Synthetic Mirror/Y, M, C, K

• Reflects the laser light emitted by the semiconductor laser of

each color onto the Polygon Mirror.

[7]

Semiconductor laser/Y, M, C, K

• Emits a laser light of each color.

[8]

Polygon Mirror

• Lets the incident laser light scan in the main scan direction and

then strike the Separation Mirror.

[9]

G1 Lens

• Corrects the condensing angle of the incident laser light.

[10]

Return Mirror/2nd

• Reflects the laser light condensed by the G2 Lens onto the sur-

face of the Photo Conductor/Y, M, C.
