Jams are almost always coil sizing or coil position, not the machine. Work through these steps in order.
1. Test the motors
Keep the door open and watch each test vend live.
Hold the top right corner of the touchscreen for 3 seconds, enter the admin password, and tap Confirm.
Tap Slot Management. Each aisle and its motor will be listed.
Tap Debug next to an aisle to spin that motor.
Confirm one full 360° rotation, no more and no less. Test each aisle 3 times.
If the refund sensor is enabled and nothing drops, the machine will alert "Please contact administrator." Wait for the alert to finish and keep testing.
A motor that does not continuously rotate a full 360° is a red flag. Call VTM Support for Tier II technical support.
2. Set the coil position
Ideal coil position is around 5-6 o'clock (see picture) so the product does not slide out on its own. Retest for a full 360° after any change.

3. Match the coil size to the product
Product too big for the coil cannot rotate. Product too small lets two items creep forward and drop together. In general, a product should have some space and should not be jammed in the coil tight.
Coil | Product |
22mm | Card packs |
35mm | Slim vapes (Breeze, Fifty Bar 20K, skinny vapes), pouch tins |
35 or 45mm | Geek Bar Pulse 15K, Raz TN9000, out of the box |
45mm | Geek Bar Pulse 25K, Raz DC25000, out of the box |
55mm | Larger vapes still in the box |
Depending on your configuration, the last item in a row may not fit.

Pouch tins (ZYN, ALP, Lucy)
Use the Tin Lifter with 35mm coils. Tins jam without it. Buy the Tin Lifter
Card packs
Card packs vend in 22mm or 35mm coils with product pushers. Every TCG machine built from July 2026 forward ships with 22mm coils and pushers installed.
Sticking in the coil: set the coil end to 5-6 o'clock and confirm the product pusher is attached. The pusher is a black plastic piece that slides onto the coil end and keeps each case moving toward the front of the aisle. Spare pushers: $8.50 for a 10-pack.
Stuck at the prize door: case height is the likely cause, not the coil.
Case | Size |
Prilino, 3-pack | 3.05" x 4.92" (taller) |
Invested Alliance, 50-pack | 3" x 4" (shorter, 180pt rigid) |
If you run the taller Prilino case: note which aisles are affected, rotate the coil to a slightly different position, and run several test vends. Still hanging? Switch to the shorter case. The pack top sticks out slightly, but the cards stay fully protected.
Still sticking?
Retest the motor 3 times after any change and confirm a full 360° each time. Then contact VTM Support with your machine serial, the aisle number, and whether it is one aisle or several.
