01

Mirror operation check

 

 

 

 

When the print button is pressed, the mirror is scanned at a speed corresponding to the currently set copy

 

 

magnification ratio.

 

 

 

 

The copy magnification ratio can be arbitrarily set.

 

 

 

 

 

 

 

02

Optical system sensors (MHPS, LHPS) state display

 

 

ON/OFF state of the optical system sensor can be monitored by the LED on the operation panel.

 

 

 

 

 

 

 

 

 

Sensor name

Operation panel LED

 

 

 

 

 

 

 

 

 

 

MHPS

Paper empty lamp (ç)

 

 

 

 

 

 

 

 

 

 

LHPS

JAM lamp (ê)

 

 

 

 

 

 

 

 

 

 

 

 

 

03

Lens operation check

 

 

 

 

The lens unit moves to the following positions of the magnification ratios continuously.

 

 

AB series: 100% 115% 122% 141% 200% 86% 81% 70% 50% 100%

 

 

Inch series: 100% 121% 129% 141% 200% 95% 77% 64% 50% 100%

 

 

 

 

 

 

04

Lens aging

 

 

 

 

The operation of SIM 1-3 is repeated continuously.

 

 

 

 

 

02

01

ADF aging

 

 

The ADF original transport operation is performed.

02

ADF sensors states display

The ADF sensors ON/OFF states can be monitored with the LED on the operation panel.

When the third digit of the multi display is “A,” the following display is made.
