MF743 Squealing at startup

Every time the printer starts to print it makes a loud pitched squealing noise. Anybody else have this problem? Thanks.

Greetings,

I suggest you try to determine (specifically) where the noise is coming from.  Then try to isolate what is causing the noise.  Something is dirty, jammed, loose, out of alignment, bent, etc.  Maybe its as simple as lubrication.    You can describe the noise, but we can't tell you definitively what the cause is.

 

If it's under warranty, call canon.  If you cannot determine the source yourself, they can best advise of your options.  If you can't get through on the phone easily, use the support portal and email.

Thanks. Nothing seems to be jammed. It still prints fine. I opened everything up and see nothing out of order. I will give Support a try.  Thanks again.
