Введение

The Control Panel of the Hewlett Packard Deskjet 3000 j310a houses all user interface controls and has an attached tray for spare blank paper. Replacing the panel will restore use of the user interface(UI) and paper tray. If neither of these are the problem then the repair is most likely done for aesthetics reasons such as a crack in the panel.
