Pro-100 - No power to the printhead after bonehead move on my part

[samboy]

Ok, can't believe I'm already having to take the top cover off my 2nd one of these printers. See picture below. I haven't found the spring yet, but I haven't looked terribly hard either. I did accidentally pop the tiny spring off next to the purple arrow, but hopefully I got that situated. The white gear doesn't exactly move freely, but it will move with some force. The motion is smooth when forced so I'm not sure if that's an issue or not. Does anything jump out at anyone in the photo? Seriously, thank you for this

OK, does the purge unit move up and down and the wiper blade slide back and forth, when you rotate the white gear.. But you will need to find that missing spring, before powering the printer back on again..

Nothing appears to be happening when I move the white gear. I still haven't found that spring either. Any idea how I can investigate that gear a little more?

Ok, update. I've found the spring. It was hard to find without breaking something else.

In this picture, I would like to make sure that I understand how the spring connects before attempting reconnection.

Does it clip onto the arms where the purple arrows are?

Also, when I roll the white gear, the other white gear on the other red arrow moves in the opposite direction. If I connect the spring, should I try powering on again, or should I do some cleaning first?

Still stumped on this pro-100. Here is a new picture. I'm not too sure what the other end of the spring attaches to. The turquoise arrow points to one of the clips I think that the spring attaches to. The other yellow arrow is a gear that looks like it might be broken, but I'm not sure. When I rotate one of the gears the gear underneath spins without affecting the gear that the yellow arrow is pointing to. Are there pictures available of what this area should look like?
