奥西TDS600/TDS9600错误代码-22011

The watchdog is a piece of hardware on the Scanner CPU IO board. It checks that the software is correctly running.

If the watchdog on the Scanner CPU IO board becomes active the operator has to switch off and on the Scanner.

After power-up the CPU-IO board detects automatically that the watchdog was active and the error is generated.

The watchdog becomes also active during test 73 when the printer goes into software-download mode.

This is also a way to test the hardware of the watchdog.
