IIRC, this is a Canon SX engine. Error 50 means the fuser did not get to the correct temperature (either too hot or too cold).
Common causes include :
The fuser lamp itself, the overheating protection thermostat (check for continuity between the pins of the 2 pin plug on the end of the fuser with the fuser removed, if it's open, then one of those has failed).
The triac Q801 in the AC input block
Capacitors and diodes on the protection PCB (the upper PCB in the AC block).
Occasionally problems on the DC controller board.
[Surely you didn't think I just fixed -- and had info -- on the handhelds :-)]
