AR-C260/C260M  SIMULATION  9 - 1

The simulation has the following functions to grasp the machine 
operating status, identify the trouble position and causes in an earlier 
stage, and make various setups and adjustments speedily for 
improving the serviceability of the machine.

1) Various adjustments

2) Setup of specifications and functions

3) Canceling troubles

4) Operation check

5) Various counters check, setup, and clear

6) Machine operating status (operation history) data check, clear

7) Transfer of various data (adjustments, setup, operations, counters)

The operating procedures and the displays differ depending on the 
form of the operation panel of the machine.
