Thought to post a couple of photos repairing my Swing Time slot, in case anyone could use it.
Removed all three reels from the machine and then removed the reel from the stepper motor. Just pop the retaining clip off and then pull outwards gently. Then it was just a matter of cleaning the reel optics with a damp q-tip along with the inside areas of the reels.
I find it odd that the quick reference sticker in the door skips over error code 40, but that's why this forum is here! Now if I could just get my Empire King slot working...that's another story.
