Coffee pots and old LaserJets on the same power line are also culprits,
because they periodically heat up and cool down on their own.

My favorite was a Coffee Pot, a LaserJet, a HP2932 printer, a
mini-refrigerator all on the same power circuit.

The symptom was the constant internal fan on the HP2932 would stop.

Subject: Re: [HP3000-L] DTC resets

If the hardware and cables have all been swapped, and the problem stays
at
the location.  I would check the console log(s) to record when the DTC
was
requesting the downloads.  Compile this to look for trends.  Is someone
intentionally power cycling the DTC?  Is a vacuum being plugged into the
same circuit causing a brown out?  Is there an elevator or large
equipment
nearby?  Is the equipment being plugged into the DTC causing a short?
