2
Check Wire Guide Adjustment
operator-intermediatemedium
Inspect the wire guide over the price wheel. Ensure the price wheel passes the price finger with a very small clearance (approximately 1/16 inch). If the guide is too far back, adjust it forward.
Expected: The price wheel physically interacts with the price finger correctly.
