Might look similar. Doesn't mean they are working.

LTG : )

Does it otherwise complete the reset?
And if it starts on 8 while another reel starts on 7 does it reset perfectly?

Yeah... not sure were asking the same question.. but what if you go into the back box and manually index the reel to 9, does it now reset?

The reason I ask, is its possible its stuck and simply freeing it up would help (not a solution, but would indicate that cleaning was all that was necessary). If its intermittent, one very likely cause (happened to me) is that the switch on the stack to trigger that reel is dirty and making poor contact- it can go from working most of the time (e.g. its not really a problem, it got stuck once or twice and I turned game off and it worked fine for weeks...) to being permanently dead due to that problem.

One thing I will say, don't go adjusting crap randomly because it "looks weird". The number of threads lately where people have been creating 10 problems trying to fix 1 is insane... so go slow and use a schematic and troubleshooting before you go at stuff with a screwdriver, etc.

If your not sure what a schematic is.. start by describing how long it was working perfectly and when you first noticed this, and if you had done ANYTHING to the game before the new problem started up.

If a score reel goes past 0 during reset process, that reel's zero-position switch (your schematic calls it "Runout") is out of adjustment.

Yep- that’s why it’s always worth forcing its hand to see what it does. If it was me I would do that a few times and confirm
Its really resetting to zero but showing a one. If thats reproducible- your good to go by fixing the wheel alignment. Try leaving it as a 2 or a 5 or a 9 even a 0 and be sure it stops reliably at the same place.

All this will do is verify the problem. Its almost for sure in the alignment- but I always learn more playing with stuff. So play a bit to confirm then watch the switch stack as you move the reel. If its adjusted wrong you will see a switch close on the zero - one crossing. Then it will open and stay open until it crosses back. That switch is hit by a piece that needs to align with the zero. If that makes sense!
