Service Manual
 
[7] SIMULATION
1. General
The following simulations are used for adjusting machine operation
conditions, trouble shooting, early detection of trouble causes, set-
tings and adjustments, and improvements for servicing.
1)
Various adjustments
2)
Setting of the specifications and functions
3)
Canceling troubles
4)
Operation check
5)
Counters check, setting, clear
6)
Machine operating conditions (operation histories), data 
check, clear
7)
Various (adjustments, setting, operation, counters, etc.) data
transfer
The operating procedures and displays depend on the form of the
operation panel of the machine.
A. Basic operation
(1) Starting the simulation
* Entering the simulation mode
1)
Copy mode key ON 
→ Program key ON → Asterisk (*) key ON
→ CLEAR key ON → Asterisk (*) key ON (Ready for input of a
main code of simulation)
2)
Entering a main code with the 10-key 
→ START key ON
3)
Entering a sub code with the 10-key 
→ START key ON
4)
Select an item with the scroll key and the item key.
5)
The machine enters the mode corresponding to the selected
item.
Press START key or EXECUTE key to start the simulation
operation.
To cancel the current simulation mode or to change the main
code and the sub code, press the user setup key.
* Canceling the simulation mode to return to the normal mode
1)
Press CA key.
(Note for the simulation mode)
• Do not turn OFF the power switch on the operation panel when
the machine is in the simulation mode.
If the power switch should be turned OFF in the simulation mode,
a malfunction may resulted. In this case, turn OFF/ON the main
power source.
• Before entering the simulation mode, check to insure that neither
print data nor FAX data are receiving.
