Friend of mine had the same problem: Turns out, that using super glue, a cannula and a small clamp, you can actually repair the broken gear. I used a small usb camera to look inside, this is what the gear looks like: It is supposed to be fixed on the metal rod in the position with the small indentions. When it breaks, it can slide sideways on the rod and will of course not rotate along with the rod. For this particular model, it is possible to fix it without even opening the case: You have to turn the printer on it’s back so that you have good access to the bottom. If you pull out (or “up” given the printers position") the papertray and fix it with some gaffer tape, you get access to a small rectangular opening on the bottom. From here you can see the gears. I used super glue and a cannula (mounted onto the super glue with a little more gaffer tape) to first secure the gear in it’s place. After that, I used a small (surgical) clamp to press the plastic onto the metal rod. After about 30 minutes, glue was...
Hi! Had the same problem… Console would charge if connected directly to the charger, but in dock, it would only blink, no charging, no HDMI output.

Hope that helps other folks with this problem…
