Our HP Color LaserJet 3525dn squeals whenever the printer warms up and when it is ejecting the page after it prints. I ran a diagnostic from the Diagnostics Settings on the onboard display and I could recreate the noise on the "Transfer Motor" test. As far as I can see, the Transfer Motors are on the Electrostatic Transfer Belt (ETB). Would replacing the ETB solve the squealing noise or am I on the wrong track? Thanks!!
