Whenever I turn on my printer, it goes through a series of checks. This printer has a paper feed scanner on top. I never use the paper feed scanner, because I haven't used it to send faxes. Just a few days ago, I turned on my printer and it started to make a strange noise. (see the link I provided)
I traced the noise to the top paper feed scanner. I tried to use the paper feeder, and found out that it does still work! But why is it making these noises?
