Symptom corrected:
When turning on the device’s main power or resuming from an Energy Saver mode,
error SC899 might occur.
Even if only Network DocBox is updated, there is a possibility that the scanner or printer
might cause error SC899 to occur.
Therefore, the following firmware should also be updated:
- Printer firmware: v1.03 or later
- Scanner firmware: v1.03 or later
