[8] SELF DIAG AND TROUBLE CODE
1. Self diag
When a trouble occurs in the machine or when the life of a consum-
able part is nearly expired or when the life is expired, the machine
detects and displays it on the display section. This allows the user
and the serviceman to take the suitable action. In case of a trouble,
this feature notifies the occurrence of a trouble and stops the
machine to minimize the damage.

A. Function and purpose
1)
Securing safety. (The machine is stopped on detection of a
trouble.)

2)
The damage to the machine is minimized. (The machine is

3)
By displaying the trouble content, the trouble position can be
quickly identified. (This allows to perform an accurate repair,
improving the repair efficiency.)
quickly identified. (This allows to perform an accurate repair,
improving the repair efficiency.)
4)
Preliminary warning of running out of consumable parts allows
to arrange for new parts in advance of running out. (This
avoids stopping of the machine due to running out the a con-
sumable part.)
to arrange for new parts in advance of running out. (This
avoids stopping of the machine due to running out the a con-
sumable part.)
B. Self diag message kinds
The self diag messages are classified as shown in the table below.
C. Self diag operation and related work flow
The machine always monitors its own state.
When the machine recognizes a trouble, it stops the operation and
displays the trouble message.
A warning message is displayed when a consumable part life is
nearly expired or is expired.
When a warning message is displayed, the machine may be or
may not be stopped.
The trouble messages and the warning messages are displayed by
the LCD.
Some trouble messages are automatically cleared when the trou-
ble is repaired. Some other troubles must be cleared by a simula-
tion.
Some warning messages of consumable parts are automatically
cleared when the trouble is repaired. Some other warning mes-
sages must be cleared by a simulation.
