[Electrical] mxm1100 on 208 volts

[Silvertoast]

have an mxm1100 at a school plugged into an outlet wired for 208.

the bare minimum for the 1100 is 208.

have had to repl the finisher control board 3 times and the lct control board once.
the finisher control brd do to f1-15 codes

when i go out for the error codes the voltage is as low as 200 volts.

called sharp and they suspect the same as me, low voltage to start with and voltage drops on top of that are frying the boards.

the schools argument is that the voltage has been 208 since install and cant be the problem since it just started doin this about 6-8 months ago.

anyone have any thoughts, suggestions, or the same experience

That seems to be the plausible explanation... no machine likes a low tension power... For the tension to be fluctuating like that either the power grid doesnt have enough juice to feed everything the client has running... or the line going from the breaker and that feeds the machine has too many equipments wich aggravates alot the fluctuations...
First action i would take would be to test the machine on a different outlet... preferably one thats not directly connected with the one the machine is on now... If still you measure a too low tension/fluctuating i'd go for a power stabilizer...
And the school arugument is... arguable... has the tension been measured at the install time?! Seems they are just trying to throw sand in your eyes and make you hold a hot potato that is not yours to begin with.
The problem is with the client's power grid... stomp your feet and argue it... the machine is not getting the minimum power the manufacturer recommends, end of story... they either reinforce it... or you can install a power stabilizer...

You have to prove to the customer it is a power supply issue. As for it being OK after install, over time, everything has to work harder as it wears, thus pulling more power. Fuser lamps are the big culprits with supply problems. Over time, especially on a 110ppm machine, those lamps will pull slightly more and more power. Belts, gears, and solenoids wearing and all driven by the boards and then throw into the mix a voltage drop. Some kind of voltage monitor would be a start and a stabilizer as hekotez suggested. Stick to your guns on this one. We had a school that had a cooking hood on the other side of the wall. When they turned it on, the machine would do all kinds of flakey stuff. We had another school that had some electrical work done over the weekend. They had unplugged the machine, did their work, and plugged the copier back into the wall. When the first teacher came in and turned it on, the finisher started on fire. The school had to be evacuated. When I got there the reading from the outlet was 189v. Schools are the worst. You would think a building full of children would have better wiring.

Schools, governments, you name it they are the worst. Most schools in PA are in buildings where some or all of the structures are 100 years old or more. The philosophy is don't fix it until someone gets injured or dies...

Everything is old and outdated, plus usually only a few offices have air conditioning so the buildings swelter to obscene temperatures in the spring and summers...it's just bad all around.

If they don't want to comply with the power requirements, tell them the only other option is to move the machine to your facility (that hopefully has proper power requirements), test it and inform them that if it works they'll be paying moving charges and hundreds of dollars an hour.
