U 1: The operation is enabled in a line other than the trouble line.
U 2: When detected during other than a job, the operation is enabled with a tray other than the trouble tray.
U 3: When detected during other than a job, the operation is enabled in a section other than the trouble paper exit section. * When, however,
the right tray is set.
U 4: When detected during other than a job, the operation is enabled in the OC mode.
* 5: Cannot be shifted to the nighttime mode/power saving function. The power cannot be turned OFF with the power SW on the operation
panel.
* 6: When the color mode is set to Disable in the Color mode disable setting of the system setting, the operation is enabled in the Black
mode.
* 7: Since communication is enabled, reception can be transferred.
U 8: When detected during other than a job, the operation is enabled in other than the DESK.
* 9: Trouble display message is displayed in 2 lines. (Example: Ready to copy. F2 trouble)
* Trouble mode process
• 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 2, 3, 4, 8, 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)
• When a trouble is detected during other than a JOB, the trouble display is not made and the trouble position cannot be selected. (The dis-
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 SIM 26-35. When this simulation is set, any trouble is written to the
trouble memory unconditionally.
(Sim.26-35)
0: Only once. If same as the previous one, it is not saved. (Default)
1: Any time. Though same as the previous one, it is saved.
