Two flashing LED's, where is the fuser triac located?
In the p/s box, or under the base?
P/s board is divided into two areas, multi-winding
and two opto-couplers between sections, but can't
reference a triac, am I looking in the wrong place?
Should I get the base plate off? Anybody got any
board circuit diagrams/schematics of any of
the Canon SX based laser printers? They are
probably all similar.

I think it is similar to the HP LaserJet III. If so it is on the AC
power board, where the cord connects.

A good picture of the board is at
http://www.printerworks.com/Catalogs...Assbly-AC.html.
That site has all kinds of HP/Canon engine printer parts and some great
parts diagrams.

The triac is the device with the heatsink just above the power switch,
below the fuser connector on the photo. You have to remove the other
board and the metal from the AC module to get at it.

I used an NTE sub on mine and it still works. I also put a better
heatsink on it since the factory one seemed small.
