Jim in Dover Delaware chiming in. I am in no way an engineer, just a Konica Minolta copier tech for 30 years. If you listen closely, you can hear that annoying "buzz" sound on just about every copier that we service. If it annoys the customer, we make the copier go into energy save/ sleep mode after a few minutes. Another fix is to cut to size a soundproof tile, remove the outer metal covering from the power supply and insert the cut tile and reinstall the metal cover. This absorbs most of the buzz noise. We have had excellent results with that. I would say 75-80% reduction in noise. Also, several times we have had the customer pay an electrician to install a dedicated 20A outlet for the copier. That really helps. It could be the copier is "starved" for current. A dedicated 20A outlet really does the trick. We have also noticed, if you have digital line filter installed, remove it and plug the copier directly into the outlet, the noise will become much less.
To check out the tiles we use, go to Amazon and paste this into the search bar "Sound Proof Sound Panels - 8 Pack 12" X 12" X 0.4" Acoustic Foam With Adhesive Stickers, Sound Absorbing Panels for Music Recording Studio Equipment, Home Sound Insulation A2S". They cost 29 bucks for a case and work great. One case of 8 tiles will take care of about 25 to 30 machines. We don't use any adhesive or tape for the install. They stay in place just fine.
