(Operation/Procedure)
1. When this simulation is executed, the mirror home position is detected.
2. When the _START key is pressed, scanning is executed at the speed corresponding to the currently set copy magnification ratio.
The copy magnification ratio can be arbitrarily set with the magnification ratio select key/zoom key.
06
Aging of mirror scanning
When the PRINT switch is pressed, the mirror base performs full scan at the speed of the set magnification ratio. After 3 sec, the mirror
case performs full scan again. These procedures are repeated until the clear key is pressed. (When the PRINT switch is pressed once,
the ready lamp keeps OFF.)
The status of the mirror home position sensor is displayed with the photoconductor cartridge lamp. (The lamp is ON when the mirror is
at the home position.)
During aging, the copy lamp keeps ON.

Operation panel display check
• When the PRINT switch is pressed, all LEDs (including 7-segment LEDs) on the operation panel are lighted. (LED check mode)
• When the PRINT switch is pressed, all LEDs (including 7-segment LEDs) on the operation panel are lighted. (LED check mode)
• When 1Up key is pressed, the LEDs on the operation panel are lighted individually from the top left to the bottom right in sequence.
After completion of all individual lighting, all LEDs are lighted simultaneously. (The 7-segment LED lights the three-digit sections at
the same time.)
Individual lighting frequency
ON: 300ms,
OFF: 20ms
• When the CLEAR key is pressed, this simulation is terminated.
• When the PRINT switch is pressed in the LED check mode, the machine enters the Key input check mode.
“Key input check mode”
When the machine enters the Key input check mode, the value display section indicates “– – –.” Every time any key on the operat ion
panel is pressed, the entered value is added and displayed on the value display section. However, the keys that were pressed once are
not counted again.
• When the PRINT switch is pressed, the entered value is added and displayed for 3 sec and all the LEDs are lighted. (LED lighting
