This description follows on from the partial ifixit tear down and is to replace a dead right earphone driver. I opened the compartment containing the right QC35 speaker/driver by cutting the outside panel with a dremel- a small circular saw used for models. After turning off the unit with the adjacent switch, I removed the ribbon cable. The cut was parallel to the plane of the earphone at the sides and perpendicular at the top and bottom. The cut at the top was through the Bose logo, to avoid damage to the microphone, switch and the driver wires. At the bottom edge, the cut went above the small acoustic port on the right, next to the USB circuit board. The driver was prised out after heating with a hair dryer, and the leads unsoldered. I cut away any plastic whiskers at the cut edges of the loose panel. and removed old glue from the bed for the rim of the driver.

Hello Gerald, 1. Open the scanner and top lid with the power on to move the printer head to the middle of the carriage. 2. Unplug from power. Pull the top end of the strut which props the lid up on the right side towards the front of the printer to disconnect it from the scanner. You may need to pry it off with a small screwdriver. 3. Remove 7 black torx screws holding the top panel of the printer. One of these is hidden behind the HP label at the right front corner of the printer. Peel the label half way to expose it. 4. Carefully pry the LCD control panel off the top panel with a screwdriver. Disconnect the ribbon cable. Just pull it straight out. Remove a further two silver torx screws hidden behind the control panel. 5. The top printer panel should now be free to remove. 6. Look down inside the right side of the printer casing near where the printheads usually park with a good light. There are two channels containing sponge saturated with thick ink- the waste ink sponges. These are not readily removed....
