Debug Log

Function Overview

Debug logs are used for analysis of program operations of the machine and identification of the problem by the developer.
This machine has a function for compiling operation history of each software module as debug logs and outputting them as unified
logs for analyzing problems.
Since the frequency of outputting debug logs and the type of logs can be changed by the settings, the settings need to be changed
according to the trouble that occurs and the situation.
Whether to change the settings is instructed by the Support Dept. of the sales company, and on-site service technicians do not
have to decide it.
Cases where logs need to be collected
• When the result of identification of the cause shows that the trouble was caused by the iR-ADV machine (firmware, hardware-
related controller)
• When the failure occurs only at the customer's site and cannot be reproduced by the department in charge of quality
management or Canon Inc.

■ Sublogs
Sublog is the general term for the unified logs for analyzing problem in which operation histories of software modules are compiled
as debug logs.
When a problem relating to the host machine occurs in the field and it is difficult to identify the cause of it at the user site, collecting
Sublogs and sending them to Design Dept./R&D can improve the efficiency of analyzing the problem and reduce the time it takes
to deal with the problem.
Logs that are saved when log saving is executed.
Logs of the Main Controller, RCON, and DCON are saved together with automatic logs as up to 10 logs
in total.
Logs that are automatically saved to the machine when an event (exceptional behavior, error code, or
reboot) occurs.
Logs of the Main Controller, RCON, and DCON are saved together with manual logs as up to 10 logs
in total.
Logs that are continuously saved while the machine is running.
Up to 100 logs of only the Main Controller can be stored.
