[Error Code] RISO SC7900 Error Beep - trying to find cause. Please help!

[filmplane]

Trying to diagnose an error beep on a SC7900 computer interface. Here is a video of it booting up:

As you can hear, there is an audible error beep and no indicator lights flashing.


I consulted the tech manual and it says:


Audio Error Signals:
The motherboard generates signals for the speaker to indicate problems, mainly during boot up. If all is okay a short tone will be heard and the boot-up sequence will continue. However if the motherboard detects an error the speaker will sound with several 'beeps'. In this case the boot-up will halt. The problem may be with the motherboard, the processor, RAM or any device attached to the board.

UPDATE: So I figured out that the yellow/green/red indicator lights are in fact working on boot up (I had to manually push them down because the wiring got bent in shipment).

Given that the lights are now working, can anyone confirm that this in fact an error beep or just a regular start up beep? Any help is greatly appreciated. Thanks!

Probably you know it already, but I can confirm that's the standard "everything's ok" booting beep sequence (same on sc7700)!
Do you have by chance a copy of the tech manual and the drivers for the sc7900?
I just got one, but it beeps constantly, something must be broken but I don't know what!

Thanks a lot,
