[8] SELF DIAG AND TROUBLE CODE
1. Self diag
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. 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 damage.
A. 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.)
B. Self diag message kinds
The self diag messages are classified as shown in the table below.
C. 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
displays 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 trou-
ble is repaired. Some other troubles must be cleared by a simula-
tion.
Some warning messages of consumable parts are automatically
cleared when the trouble is repaired. Some other warning mes-
sages must be cleared by a simulation.
Class 1
User
Warning of troubles which can be recovered by 
the user. (Paper jam, consumable part life 
expiration, etc.)
Serviceman
Warning of troubles which can be recovered only 
by a serviceman. (Motor trouble, maintenance, 
etc.)
Other
Class 2
Warning
Warning to the user, not a machine trouble 
(Preliminary warning of life expiration of a 
consumable part, etc.)
Trouble
Warning of a machine trouble. The machine is 
stopped.
Other

• Machine operation enabled under some conditions.
The operations excluding the trouble mode are enabled (READY). For the mode where operations are disabled, only setting is enabled and
the operation disable message is made.
(NOT READY)
(Display) A dialog is displayed when a trouble occurs. For the mode where operations are enabled, [OK] button is added to the message.
When operations are disabled, [OK] button is not displayed, and the message is displayed until the trouble is cancelled.
* For U 1, 3, 5, 6, 7, perform the following procedures. (In order to avoid patent interference.)
• When a trouble is detected during a job, the machine operation is terminated. (Trouble display/without [OK] key)

play is not turned off. Machine/Button)
• Troubles which disable the machine operations
The trouble display is always made, and all the modes cannot be set.
• Writing to the trouble memory
Writing of a same trouble to the trouble memory can be selected with SIM26-35. When this simulation is set, any trouble is written to the trou-
ble memory unconditionally.
(Sim26-35)
0: Only once. If same as the previous one, it is not saved. (Default)

• When the power is turned ON and each trouble of H3, H4, H5, U1, U2, U6 (09) is stored, it is judged as a trouble immediately.
* For A0 and E7 troubles (connection troubles), only the connection trouble information is saved, and they are not regarded as save troubles.
(There is no way to delete the communication trouble information.) (Detected every time when the power is turned ON.)
