Brother D006DG001 is the touch panel assembly listed for the MFC-L9570CDW printer. It is a panel component intended for the printer’s touch interface, making it relevant when servicing that part of the machine’s control panel.
The parts manual identifies D006DG001 specifically for the Brother MFC-L9570CDW. It lists the touch panel assembly separately from the LCD, panel circuit board and other panel components, so this part reference identifies the touch panel assembly rather than the complete control panel.
