I searched for “commodore MPS-802 circuit diagram”. 😊

Yes, fuse is good. First thing I checked when it was totally dead.
And yes, on closer inspection, that that might be glue.
I'm not an expert, but I can trace some power wires and connectors and check
for continuity here and there.
Does anyone know what the voltage should be out of the transformer?
Ben

Hey guys,
I pulled a Commodore MPS 802 printer out of storage. I figured it would be a
nice upgrade from my MPS 801. Unfortunately, it did not power on. On closer
inspection it appears that these two capacitors (attached photos) are done.
Actually, I don't think those are bad. Most large caps have some glue on them
to physically hold them to the PCB. From the pics, it appears that is jsut glue
I believe the 802 has a fuse. Is it known good?
