Diagnose Recurring Product Jams
This diagnostic path is for machines that repeatedly jam products, requiring a review of the entire dispensing sequence, from selection to final drop.
- If the jam is suspected to be related to motor output or electrical control, hand off to a qualified technician for detailed electrical and mechanical review.
