[10] SELF DIAG MESSAGE AND TROUBLE CODE

MX-LCX3N

1. Self diag

A. General
When an error 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 remote email diagnostics. This allows the
user and the serviceman to take the suitable action. In case of a
failure, this feature notifies the occurrence of a failure and stops the
machine to minimize the damage.
B. Function and purpose
1) Securing safety. (The machine is stopped on detection of a
failure.)
2) The damage to the machine is minimized. (The machine is
stopped on detection of 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. (This avoids stopping of
the machine due to running out the a consumable part.)
C. Self diag message kinds

Class 1 User Warning of troubles which can be recovered by
