Squeaking noises from Canon Imageclass MF634CDW

[CGWade]

My eight-month-old MF634CDW has started to make an annoying squeaking noise when it prints and when it does its periodic warm-up (or whatever that is when it mysteriously turns on by itself for a minute or two and seems to be "clearing its throat" at odd times). Not sure, but this new noise may coincide with changing the black cartridge. 

Replacement cartridge is regular issue (not third party) 045-H purchased directly from Canon. Have removed the cartridge and found no evidence of damage. Already recycled the old catrirdge, so re-inserting it to see if that stops the noise is not an option.

Where do I go from here?

Thanks.
