5. Breakdown sequence
A. Breakdown mode process
(1) Breakdown mode list
There are following cases of the breakdown mode.
∗ For FAX communication, refer to the sheet of “Call request and Call-
in.”
∗ The machine may be operated under some conditions.
∆1: When detected except when in a job, the machine can be operated
in the OC mode.
∆2: Can be operated except in the staple mode.
∆3: When detected except in a job, the machine can be operated
except with the breakdown tray.
∆4: Can be operated with some restriction on the image quality
depending on the destination. (Low density print) * Refer to the
process control trouble operation table below.
∆5: When detected except in a job, can be operated except in the trou-
ble paper exit section.
∆6: When detected except in a job, can be operated in the single sur-
face scan mode.
∆7: Can be operated except in the inserter tray, if the error is detected
in the standby mode.
