AR-LC6  TROUBLESHOOTING  7 - 1
[7] TROUBLESHOOTING
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.
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.)
3. Self diag message kinds
The self diag messages are classified as shown in the table below.
4. Self diag operation
A. 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 dis-
plays 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 trouble is
repaired. Some other troubles must be cleared by a simulation.
Some warning messages of consumable parts are automatically
cleared when the trouble is repaired. Some other warning messages
must be cleared by a simulation.
