[10] SELF DIAG MESSAGE AND
TROUBLE CODE
1. Self diag
A. General
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 or notifies to the user
or the serviceman by voice messages. This allows the user and the
serviceman to take the suitable action. In case of a trouble, this fea-
ture notifies the occurrence of a trouble and stops the machine to
minimize the damage.
B. 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
stopped on detection of a trouble.)
3) By displaying the trouble content, the trouble position can be
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.)
C. Self diag message kinds
