You stop and then after you clear it make sure you re-sync it. 8" in then out 3x's over to re-establish the stop point. If you don't the slide will eventually get sideways and jam. Easier to make sure the unit is clear prior to.
I've had to stop mid stream, but immediately do a re-sync once the issue is resolved. If you buy a unit ask the dealer to show you the process at your PDI. You tube also is a resource for other issues.
