Introduction
The System error 79:04 is a generic firmware error (equivalent to a blue screen in Windows). It’s the System
Error that the printer will display when an unknown exception occurs that cannot be pointed to by any specific subsystem of the printer.
Since this is a generic error, there can be multiple causes behind it. This document will cover the most
probable causes behind a system error 79:04 and will recommend the most efficient troubleshooting steps to resolve customer issues.
One important point to mention is that, although 79:04 system errors can be caused by a hardware
malfunction, the vast majority of 79:04 system errors are pure software or firmware issues. In these cases
the issue can only be solved by determining the root cause and implementing a solution. The solution can usually be applied by either correctly configuring a selection, updating the printer’s firmware/software that is being used or by fixing an error in the code).
