How to troubleshoot the 79:04 System Error 71
Troubleshooting
• The printer logs.
Front panel displays 79:04 while printing
A. While printing a single job
The error happens after a single job is sent. It’s easy to identify which job that has produced the error,
since every time that this same job is sent, the error is replicated.
B. Random 79:04 during continuous printing
The error does not happen with a single job. It happens randomly during continuous printing, normally
while the printer is managing a heavy load (printing a project or in a reprographics environment).
This type of error is caused either by memory leaks or by concurrence issues in the printer’s firmware.
They normally happen in non common environments where these memory leaks or concurrence issues that
have not been detected during qualification have occurred. These issues cause the printer to crash at a
completely random moment during printing, and are not associated to a specific job.
1. Reboot the printer.
2. Upgrade the printer’s firmware. Even if the currently installed firmware version is the latest one, re-
install it.
3. Escalate the issue, providing the following information:
• Unit information: S/N, P/N, accessories
• Conditions where the problem occurs and conditions prior to the first occurrence of the issue.
• The result of the previous 7 steps
• The printer information pages (either printed and faxed or obtained through the Embedded
Web Server)
• The System Error detailed information (it can be obtained by pressing CANCEL + Down)
• Information on the workflow:
-Operating System
-RIP
-RIP Driver version
- Settings in the driver and the application
- Settings in the RIP
- Connection method and settings:
- The original file along with the information on how to reproduce the issue
- A print to file that can reproduce the issue
•The printer logs.
