How to replace the installed Touchscreen Control Panel

Initially, you must switch the HP LaserJet Pro 200 M251nw off, and then unplug the power cord. After that, you must remove the cassette tray from the main unit, and then open the front door. Now, you must remove the fixing screw and release the tabs of the right cover, and then remove the right cover by rotating it away from the main unit. Once you have removed the right cover, you must remove the left cover by releasing the corresponding tabs and removing the fixing screw, and then detach the rear right cover by releasing the two tabs. In the next step of the replacement procedure, you must open the rear door, and then detach the rear upper cover by releasing the two locking tabs. After that, you must remove the fixing screw of the upper cover, and then release the tab and the peg of the cover. Next, you must unplug the FFC from the PCA, and then detach the grounding strap. Now, you must remove the upper cover by releasing the remaining tabs, and then detach the control panel FFC from the upper cover and the bracket. Once you have detached the FFC, you must remove the two screws that secure the exhausted/defective Touchscreen Control Panel, and then remove the exhausted/defective component from the HP LaserJet Pro 200 M251nw. Finally, you must unpack the new Touchscreen Control Panel, and then install it by executing the current procedure in reverse order.
