1. General
When a trouble occurs in the machine or when the life of a consumable
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 ser-
viceman by voice messages. 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 dam-
age.

viceman by voice messages. 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 dam-

2. Function and purpose
1) Securing safety. (The machine is stopped on detection of a trou-
ble.)
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 stop-
ping of the machine due to running out the a consumable part.)
