HP CM4540 MFP Communication Lost (device <-> control panel error)

[lane1957]

Hello everyone!

I am new to the forum, but looking forward to interacting with such a talented group of people.

I was wondering if anyone has seen this error message on an HP CM4540 MFP. When I power it up it displays this error message on the Control Panel "Communication Lost (device <-> control panel error)". I have the service manual on this unit, but sheds very light on what may causing this issue. I suspect it is due to a bad/faulty HP secure hard drive, but am unable to test it. Anyone have any idea?

Thank you to all!
