Whining noise in brand new Canon MF644Cdw


I unboxed a new MF644Cdw and, while it functions correctly, the whining noise it makes when warming up and printing, seems extremely loud.  I can hear it upstairs through a closed basement office door.


I called tech support and they said it sounded pretty normal.  I was on a cell phone, so I think the level was being attenuated by noise management don't by the phone.  


Is this normal????


Video with sound of warm up after plugging in attached:




Me personally, I think it sounds a bit loud, but if you are holding the recording device right next to it, maybe its sounds worse than it actually is.  You might visit a retailer and compare if possible.

Yeah, it is hard to tell how loud it is without hearing some other familiar noises in the same space to compare/contrast.  My local retailers don't seem to have a comparable unit in stock, let alone set up, to test in person 😞  Thanks.

This is a new video recorded from 5-6 feet away.  I'm standing right next to the mic when I talk for reference.

Hi Evaneaston,


The printer sounds normal. The sound may be applfied by where it is located. You stated it is in a basement.


You may want to check to ensure all packing material was removed. You can also remove and reset each toner cartridge.

I ended up returning my MF644Cdw and getting a MF743Cdw instead.  It is much quieter and has no whining component to the noise it does produce.
