Power At The Wall Outlet

False error codes / Strange copy quality / Random paper jams / etc.

Truly there are too many examples to mention where power at the wall outlet could be causing you problems. So many times we troubleshoot a machine forgetting that the incoming power at the wall should be our first test.

Many of you will shrug off this tip and think I’m off my rocker; but trust me when I say I have seen it enough to post it here. I always get “push back” from technicians when I suggest wall voltage. “How can it change over the years the machine has been here?” they ask. Think about it…

  • Wintertime, customer gets cold, plugs in a space heater to the same circuit as the MFP.
  • Customer buys a new/old fridge for the break room. (on the other side of the wall)
  • Customer add a new florescent light to their desk. (on the same circuit)
  • Machine has been pushed back into the outlet dislodging the box and damaging the conduit.

I could go on and on (Yes I have seen each one of these examples).

The next question I get is how do I test the outlet and what should my multi-meter read? Below is an example of a 15amp outlet.

H = Hot or Line voltage (should read 115 to 120VAC)
G = Ground (Ideal is 0, MUST not be more than 1.0VAC)
N = Neutral (Should be equal to Hot. No more than 5 % difference)

Lastly, Sharp suggests all MFP placements be installed on a dedicated circuit with NO Extension cords & a SURGE SUPPRESSOR.
