[9] SELF DIAG MESSAGE AND TROUBLESHOOTING
[Error code]
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. This allows the user and the ser-
viceman 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.
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.

(2) Trouble mode process
The machine can be operated under some conditions.
Operations except for the trouble mode are enabled (READY). For the
modes which cannot be operated, only setting is enabled and a mes-
sage is given to show the operations are disabled. (NOT READY in this
case)
(Display)
When a trouble occurs, a dialog is shown. In the mode where the oper-
ation is enabled, the OK button is added to the message. In the mode
where the operation is disabled, the OK button is not shown and the
display is kept until the trouble is canceled.
(3) Writing to the trouble memory
In case of a same trouble in this machine, selection is made with the
simulation to write into the trouble memory or not. If this simulation is
set, any trouble is written into the trouble memory unconditionally.
(SIMULATION. 26-35)
0: A same trouble as the previous one is not written. (Default)
1: Any trouble is written into the trouble memory unconditionally.
B. Power ON trouble detection sequence.
• When the power is turned ON, if H3, H4, H5, U1, U2, PF, L4-31, F3-12/22, or U6 (LCC-related sub code 09 only) is saved, a trouble code is imme-
diately displayed. E7 (50, 55, 56, 57, 60, 65, 66, 67) trouble is not saved.
