Magnetic card inserted in opposite side by Dummy

[jftman]

Me Dummy, Calculator Dyslexia.
When finishing a gummy wheel repair I put a card into the slot to get a feel for the pressure on it, as it come in contact with the innards on it’s path.

But my poor brain! Why I inserted the card into the opposite end on the left side instead of the right side IDK…….

The motor does not move in operation and could I have done damage with my mistake.
I confess, I have made this gummy repair but I never removed the motor to know if the gears and rubber stuff is all clear. But since I did have Card Dyslexia I am uncertain what I may have done. Absolute damage? The switch plate was designed to guide the from the proper side.
Idiot PROOF?
