Canon C1 exploding noise

[sargas]

Hi all!

Yesterday I finished my work day fine and turned off my copier with forced shut down, as I was lazy to wait long...
Today, upon turning the copier on I could hear exploding sounds every couple of seconds and before I was able to turn the power off, no errors were shown.
It appears as if the sounds come from the back of the printer.
I pulled the central part (heating station and transfer belt) out and started the printer again. This time it took longer before the sounds appeared.
On inspection I could find no physical damage.

I took the back panels off, there was also no apparent physical damage.

It doesn't sound like mechanical damage... I have really no idea, please help...

My technician can come first tomorrow noon, so any opinions and advice are *really* welcome.

With kind regards,
Sargas

Usually a loud crunching noise is from a shaft located on the Developing Drive Assembly on FIGURE 270 item #2 with part number FC6-1436-000.
