While I appreciate the instructions on how to change the scanner bulb, what would be more useful is some info on where to find/buy the actual bulb itself.

Unfortunately the www.coinchange.co.nz link is no longer valid. Is there another source for the bulb? Thanks in advance!

I opened up my Canon MF-8580CDW scanner which is the same. As I was putting it back I found two springs laying in the base and cannot find where they go. Can you or anyone help me by telling me where they go? (I know about the belt spring tensioner. This is not that spring)

Was it determined where the springs go? I am having the same issue.
