High pitched electrical whining noise

[georgeherd]

Hi, 

I have recently bought and installed this printer.  While in sleep it emits a high pitched electrical whining noise.  This is impossible to live with in my small home office.  Any ideas?

I have tried 2 different locations and plug sockets.

Hello George,

I would recommend contacting the Support Department for more assistance.

I just got my unit in today and have exactly the same issue: a high-pitched whine 12.4-12.5 kHz that starts as soon as the printer enters sleep mode. I have attached a screenshot of a spectrum analysis tool that I run on my phone. Did you get this resolved through support (I am having a hard time registering for Xerox support)?

A service engineer from Xerox came by today, but was unable to hear the noise (ability to hear high frequency noises is heavily age-dependent) and even though I was able to show the clear peaks at 12.3-12.5 kHz he was reluctant to start swapping out parts at random. Next step is to contact the dealer and see if I can either get a replacement unit (if that does not have the same issue) or a refund.

My printer arrived just today and is also making the noice. It's really annying and my setup is such that the printer sits right next to me on the table.

I have returned the Xerox to my dealer who was kind enough to offer a full refund. I exchanged the Xerox for a comparable HP model, no noise whatsoever. Specs-wise I would have prefered the Xerox, but since they are not acknowledging the issue - which to my ears is a severe defect that would also stand out in a larger office - I had no choice.

Having done some reading I found out that most countries do not have regulations on noise production above 8 kHz, so I am guessing that Xerox does not test for this issue, but is sounds like a product-related defect to me.
