Mirror scan operation
(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.

SPF sensor status display   
ON/OFF of the sensors in the SPF can be checked with the following lamps.  
03
Motor ON  
(Operation/Procedure)  
When the start key is pressed, the SPF motor rotates for 10 sec at the speed corresponding to the currently set magnification ratio.
04
Paper feed solenoid ON  
(Operation/Procedure) 
When the start key is pressed, the SPF paper feed solenoid repeats ON (500 ms) and OFF (500 ms) 20 times.
05
01
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 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 operation 
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
check mode)
(Note for Key input check mode)
• Press the PRINT switch at the end. (If it is pressed in the middle of the process, the entered value up to that moment is displayed for
3 sec and the machine enters the LED lighting check mode. (ALL the LEDs are lighted.))
• Multiple key inputs are ignored.
02
Fusing lamp, cooling fan operation check
When the PRINT switch is pressed, the fusing lamp repeats operations of 500ms-ON and 500ms-OFF 5 times. During that time, the 
cooling fan motor rotates.
03
Copy lamp ON 
(Operation/Procedure) 
When the START key is pressed, the copy lamp is lighted for 5 sec.
06
01
Paper feed solenoid ON  
(Operation/Procedure) 
When the START key is pressed, the paper feed solenoid selected by the tray select key repeats ON (500ms) and OFF (500ms) 20 
times.
02
Resist solenoid ON  
(Operation/Procedure)  
When the START key is pressed, the resist solenoid (RRS) repeats ON (500ms) and OFF (500ms) 20 times.

(Operation/Procedure)
1. When the simulation is executed, warming up is started.
2. Warm-up time is counted and displayed every second on the copy quantity display.
3. After completion of warm-up, the time count is stopped and the ready lamp is lighted.
4. Press the clear key to clear the warm-up time display, set the copy quantity, and press the START key, and the machine will copy 
the set quantity repeatedly.
This simulation is canceled by turning off the power or executing any simulation which performs hardware reset.
06
Intermittent aging
(Operation/Procedure)
1. When the simulation is executed, warming up is started.
2. After completion of warm-up, the ready lamp is lighted.
3. Set the copy quantity and press the START key, and the machine will copy the set quantity repeatedly.
4. After 3 sec of the interval time from completion of copying the set quantity, the machine will resume copying.
5. The above operation 4 is repeated.
This simulation is canceled by turning off the power or executing any simulation which performs hardware reset.

01
Main motor operation check (Cooling fan motor rotation check)
When the PRINT switch is pressed, the main motor (as well as the duplex motor in the duplex model) is operated for 30 sec. If the 
developing unit is installed at that time, the developing bias, the main charger, and the grid are outputted together in order to avoid 
toner consumption. Since, in this case, laser discharge is required when stopping the motor, the polygon motor is rotated at the same 
time. If the developing unit is not installed, the above high voltage is not outputted and only the motor is rotated.
: Do not execute this simulation by forcibly turning ON the door ON/OFF switch.
