[7] SIMULATION
(Diagnostics, setting, adjustment value
input, data display)
1. Outline and purpose
There are following, simulation functions to check the machine
operations, troubleshoot, find causes, make various settings, improve
adjustment work speeds and serviceability.
1) Various adjustments
2) Specification and function setting
3) Trouble cancel
4) Operation check
5) Counters check, setting, clear
6) Machine operation conditions (operation history) data check, clear
7) Transmission of various data (adjustment, setting, operations,
counter, etc.)
The operating procedures and displays slightly differ from the form of
the machine operation panel.
The typical forms are as follows:
1) Code system: Values input and mode selection are made with the
10-key pad and various function keys.
2) Switch system: Simulation mode selection is made by
combination of switch setting.
3) Values and mode selection is made with various function keys. As
a special one, a jumper wire is used to connect the check points
on the PWB to select the desired mode.

A. Operating procedures and operations
*
Entering the simulation mode
1) Program (P) key
®
Interrupt key
®
Clear key
®
Interrupt key
(The machine enters the standby mode for the simulation main
code.)
2) Enter the main code with 10-key pad.
®
Press START key.
3) Enter the sub code of with 10-keypad.
®
Press START key.
4) Select the mode and the item with the 1-key pad and the function
key.
5) The machine enters the selected mode.
To start the simulation, press the START key or the function key.
To cancel the current simulation mode and to change the main
code and the sub code, press the interrupt key.
*
The simulation mode is canceled and the machine returns to the
normal operation mode.
1) Press the all clear key.
SIM 46-12, 13, 14, 15, 16, SIM66 and SIM68 are provided only for Japan
models (FAX mode/ASK/IrDA).
