    HP M551 making odd noise

    We have two customers, both with a HP M551 that is getting an odd squealing noise from the upper left part of the machine. When you go in and run the individual motors, the noise never comes up. We've tried a fuser, cyan image unit and HV board. We also took one of the printers out of the building and brought it to our office to see if we were getting bad electricity.

    None of the above troubleshooting worked. Any ideas?

    My question is these machine are both doing the identical sound?
    Are these OEM original Cartridges?
    I would try the other toner cartridges.

      Yes, it is the same identical sound and yes they are using OEM cartridges.

      If by other toner cartridges you mean the other colors, we thought about that but since it seemed to be centered around Cyan and it never came up when you ran the motors we didn't go that far. I'll suggest to the tech to try that.

        Try replacing the cartridges beginning with the most likely one, then the others if that doesnt cure it. If no new cartridges cure it, next step would be to replace the ITB (intermediate transfer belt).
