Inspect the banknote entry slot and path within the bill validator for visible obstructions or foreign objects.
Carefully open the bill validator's access panel (if available) and remove any jammed banknotes, torn pieces, or debris from the banknote path.
Inspect all banknote path sensors (e.g., optical sensors) for cleanliness, alignment, and proper function after clearing the jam.
