      I was thinking the same. Is it on a surge protector? If so, it may be bad. If not, you may try one.

        Surge protectors don't help if the problem is sags, slow changes or floating ground. Floating grounds can kill.

        I have had bad grounds cause Lanier 1200 word processors to erase files on floppy disks. It was a portable building on a military base. The outlet grounds were tied to the building frame. Regional rep came up from LA with a Dranetz 3 port monitor. Hooked it up and started getting multiple hits a minute to include hot to ground and neutral to ground. Base engineers came out the next day, sunk a 12 foot ground rod into sandy soil, tied the building ground to the ground rod and the problem went away.

          Surge protectors are a useful tool in diagnosing power issues. Which is a possibility in this particular situation.

            The thought crossed my mind, but that machine went in to replace a MPC6000 - and that's a beast of a machine and, in my opinion, much more sensitive to those kind of things.

            I also thought "hey, maybe they're trying to use the MPC6000 at the same time, and that's a power hungry beast", but no - the customer has had the machine powered off for a while, since it's got no contract.

            I went there today and replaced the PSU. Let's see how it goes.

              that is only if it was designed for copiers. such as innovolt or etc... if it is a cheap you know what from the store then no..... not on a laser copier/printer. if you put a cheap surge protector on a laser machine. then you are just begging for issues. the cheap ones from the local store are not rated to handle the power load. just my 2 cents on that one...

                The only things from the trouble shooting guide for SC544-02 that you haven't listed is the PSU and the BCU. Also check the wiring harness for bad/loose connections from the Non Contact thermistors and the thermopiles to the BCU and BCU to the PSU.

                  It didn't go well.

                  Boss decided to loan the customer another equipment and bring that back to the shop so it can be analised.

                  Will keep you posted.

                    Oooh Hey, how did we get on with this? I assume it didn't fault again onsite and didn't fault again in the workshop.
