Case Details of Problem
Case D
When an E code error has
occurred
Case E Problems other than
above
NOTE:
When an unexpected error, E code error, or problem of restart occurs, the log can be automatically saved to the hard disk. To
automatically save logs to the hard disk, confirm that the following service mode is set to the default value. For models without the
service mode item, no check is needed because it is already set to the default value.
• (Level2) COPIER > Function > DBG-LOG > LOG-TRIG > 101
■ Tools Required
One of the following tools is required to obtain the debug logs of the machine.
● Exporting to a USB Device
• USB device
When exporting debug logs to a USB device, use a USB device in which the system software for the device is registered
using SST.
Since the size and number of log files to collect varies according to the device status and the logs that have been saved, the
size of the collected files may be several hundred MB. Therefore, it is recommended that you use a USB device with 1 GB
or more space.
The USB device must be formatted with the FAT file system.
● Exporting to a PC
• PC with SST installed
• Network connection cable
When exporting debug logs to a PC, a PC with SST installed and a network connection cable are required.
● Common
• DEBUG SRAM PCB ASS'Y Board
Only when determined to be required by the above "Flow of Determining the Procedure for Retrieving Logs".
NOTE:
With this machine, a standard function included with the device can be used to save the debug logs (Sublog) to the hard disk
without using the DEBUG SRAM PCB ASS'Y Board.
However, the DEBUG SRAM PCB ASS'Y Board is specified as a tool to use because a Sublog Board with a battery is required
when it is necessary to restart the machine to reproduce the problem that is occurring.
● Installing the DEBUG SRAM PCB ASS'Y Board

Not needed. Collect the log from the HDD with SST, etc. However, if the background of
the Control Panel is solid black and an error code is displayed in text, logs
cannot be obtained.
Not needed. Collect the log from the HDD with SST, etc. Check with the user on the date
