Debug log

Scope of Application

■ Purpose

• When the Canon quality-appointed staff determines the need for an analysis of debug log
by the R&D department, we ask the field to collect log for an investigation to determine the
cause.
• This is intended to improve efficiency in log collection when a trouble occurs.
● Adding Users for Log Collection
Collecting logs previously required operation in service mode.
Automatic Storage:
To set the types of logs to be stored and the timing to store logs in the HDD.
Lev2 COPIER > FUNCTION > SYSTEM > DOWNLOAD > DEBUG-1
Default value:3:
Save SUBLOG in overwrite mode at detection of Reboot/Exception/Encode
The details refer to an item of DEBUG-1.
Manual Storage:
Execute "Counter Key(10 sec. or longer) + 1.2.3" to save the debug log.
● Collecting logs:
SST or place USB memory
COPIER > FUNCTION > SYSTEM > DOWNLOAD > OK

Overview

■ Function Overview

Debug log is an integrated log for failure analysis that gathers logs prepared by the software
modules in the device for debug purpose.
In the case of a field failure that is hard to be reproduced, this measure is intended to improve
efficiency in failure analysis and reduce the time for failure support by collecting debug log at
the user site (which was created immediately after the failure) and sending it to the R&D.
When the Canon quality-appointed staff determines the need for an analysis of firmware
debug log by the R&D department, we ask the field to collect log for an investigation to
determine the cause.
● Effective Instances of Collecting Debug Log
• The error occurs only at the customer site and cannot be reproduced by the sales company

or the Canon staff who is in charge of quality follow-up.
• When the error frequency is low.
• When the error is suspected of links with firmware rather than a mechanical/electrical
failure.
* Collection of Sublog is not necessary when the reproduction procedure is identified and
the error can be reproduced by the sales company HQ or the Canon staff who is in charge
of quality follow-up.
With imageRUNNER ADVANCE, Sublog can be saved in the HDD using the standard
function of the machine without using the Sublog Board.
The Sublog Board is also assigned as a tool with imageRUNNER ADVANCE. The Sublog
Board is required for an error that requires rebooting because the Sublog Board has a battery.

Storing System Information

■ Storage Method of System Information

● Automatic Storage
At the time of shipment, 101 is specified in service mode Lev2: COPIER > FUNCTION >
SYSTEM > DEBUG-1 to 3.
Debug log is automatically stored in the case of the following:
Exception + E-code + reboot
The log consists of the number of 10 logs from the latest log extended to the older logs.
● Manual Storage
Counter Key + 1.2.3
Execute "Counter Key + 1.2.3" to save the debug log.
Note that the Control Panel is locked during the saving process; therefore, the screen does
not change even though you press the OK button on <Check Counter>.

■ Description of Log to be Collected

The log consists of the number of 10 logs from the latest log extended to the older logs.
Latest log ten are always left.
Logs older than the specified period are overwritten (deleted).
When collecting logs from the machine, the log file in the machine is deleted.
