Canon Pro-100 Took a tumble and now I cannot get it working properly

I don't have anything to add other than that I am amazed and impressed by your persistence, and I am watching as a spectator. If you pull this off and breathe life back into the printer, I think it will be something akin to this clip ;)

Can't quite make it out, but it looks like some circuit traces are broken. Easily jumped by someone handy with soldering. Be careful to be precise and make no shorts or game over.

Ok, I got the piece off. The chip is broken, but I should be able to glue it back together. Should I check it somehow with my multimeter? See attached

Just glue wouldn't repair the broken traces, but you could potentially repair this board by adding bridge wires to the solder points over the broken area. It's a single sided PCB so you can follow the traces by eye going from solder point to solder point.

Obviously replacing the board would be more reliable and preferable but if you're really desperate it might just be repaired this way. And then verify continuity with your multi meter.

I agree with @nerdful1 snd @x64 bridging the breaks with short wires would be most reliable. Using a soldering iron made for electronics is better than the household soldering gun. I don’t know what components are in the board yet some electronic components are sensitive to heat and voltages. There is some risk with continuity testers as they do apply an unspecified voltage while testing. Also, somehow that board is electrically connected to the rest of the printer. That was not clear how. These connections would need to be solid and undamaged or repaired as well.
One thing to watch out for is if the repair process is introducing new damage, it is time to step back and reconsider your alternatives. Just my opinion of course.

I have tried everything, and nothing ever changes with the startup process. It just goes through the same iterations and same exact thing to a T. You'd think if I were going down the right path that it would at least start making a different noise or something. I've soldered, I've epoxied, I've tried lining the plastic discs up by counting cogs in the pictures, but nothing ever changes.... UGGH, I'm so frustrated.

I would have gotten to that point quite a bit earlier than you. Here are my thoughts, yet topics can only be answered by you.
Many projects come down to tradeoffs among scope, schedule, and resources. What is the scope that needs to be done (more than you thought and uncertain how much more), schedule (when do you need the project completed), and resources (how much time you want to spend on it, or spend to bring an expert onboard, or spend with new equipment).
Those tradeoffs all depend on the individual and the individual's situation. Yet, it usually starts with stepping back and acknowledging reality (whatever it is for you), making decisions on how to move forward, and then taking those steps. It's often hard, yet it's often a healthy thing to do.
Pretty standard with projects to have checkpoints on how things are going, reassess, and make course corrections to head towards a better outcome.
Sometimes, reassessing one's needs for the result can be fruitful, too.
The frustration is real, and I acknowledge that. Sometimes taking a break from the project brings new ideas as well. Hope these thoughts may help you move forward.

Thanks for the sentiments. That is helpful and makes tons of sense. What is killing me about trying to fix it is that I had a second one unused that I opened and took the ink and print head out of and put it out by the curb. I think that's been the main driver on me getting to the bottom of this.

As for moving forward. Is this the only printer model that I can use my CLI-42 ink cartridges and refill bottles and ink chip reset mechanism on?

I have an alternate HP 8020, and I am amazed that people pay what they do for ink. I like to take pictures and print pictures and have them show up around the house for my 3 boys to notice and hear their reactions. I like to use a lot of ink and not worry about it. Any advice? Thanks again for all you guys help, but it might be time to take this thing out to a field and go all "Office Space" on it.

Are you still getting the same error messages, even after your repair..

Maybe it’s time to rethink what you’ve done and start over again, you might get it better the second time, I wouldn’t give up just because of a little set back, :thjust think how it will make you feel when it cranks into life again..
 
I believe it's still the 17 orange and white blink cycles. For some reason, I had initially thought it was 16 when I called Canon support and they offered to sell me a new printer at a discount for 1,100. Another thing is that I tried a lot of service tools on it. Most of them gave errors on just about everything. I was able to export a data file from a few of them. Would that information be helpful?
