Well, you certainly should have kept some parts from the series 1 --
they're getting very hard to find (heck, even toner cartridges for the CX
are getting hard to find) and there are machines that depend on them. In
particular, the DC controller board, scanner assembly, fuser parts, etc.

And amny of the parts in the 3 are the same as in the 2 (SX engine). So
if you stipped the 2's, you should probably have done the same with the 3

The mechanical side is solid on these machines. The only common
mechancial failure points are the pickup rollers and the fuser roller.
The former fails to grip the paper, the latter gets scored. Oh, sometimes
geats in the fuser shed their teeth...

However, mechanical parts tend to be available and cheap-ish. Unlike
electronic parts where you can only get complete PCBs officially. So you
should save the electronics first.

Yes. It _is_ a halogen bulb.

For the bubl? Clean it with propan-2-ol.
