The HP B3Q10-60145 Control Panel Mount Chassis Assembly is a printer part designed to mount the control panel. Its specific role makes it distinct from the control panel itself: this is the chassis assembly that supports its mounting.
The distributor listing identifies it as a compatible part for selected HP LaserJet Pro MFP printers, including M426fdn and M426fdw. It is intended for use as a replacement chassis assembly in the printer’s control panel mounting area.
