My Cash Drawer Won't Pop

The cable that runs from the cash drawer to the back of the printer may be in the wrong port on the printer. This one's happened a few times. The printer has an Ethernet port in the back of it for use cases where you're just hooking it up to a computer network as opposed to a computer, and the cables have similar ends.

The cable for the drawer can be jammed into it if someone is intent enough. The cable should have a little resistance before it clicks into place, but you shouldn't have to force anything. Verify it's in the right port on the printer and give it another go.

If you're still having trouble, you can reseat the connector on the drawer, which is under the drawer.
