Alas I've only worked on series 1 (CX) and 2 (SX) printers. But those I
have _worked_ on (as in totally taken apart, investigated, reassembled --
without the manuals).

Maybe an SMPUS that's tripping due to a short on the secondary side
somewhere. Could, of course, be a short in the load (e.g. motor driver,
decoupling capacitor)

The SX is _very_ modular and comes apart into official FRUs in about 10
minutes. The CX is somewhat worse, some of the sctions come out in bits.
None-the-less these are not that hard to work on, so I assume the IIISi
is not too bad either. The outer casing should come off easily when
you've found the right screws....
