Who has this printer squeaking all the time? It is actually very quiet, but you can always hear a slight squeaking noise. I wanted to send the printer in and got a Brother MFC-L3730 CDN on loan. Unfortunately it squeaks even more! Is that just part of the Brother printer? It's really annoying, especially as I've never had this with HP/Kyocera etc. (I'm sitting next to the printer and have to print a lot for business). Many thanks for your help, unfortunately I couldn't get any further with Brother itself....
