Had an AccuFeed that misfeeds within 10 ballots. Changed the centre tire on the feed arm. Still misfeeds. Tried an old photocopier trick (my background) and ran 720 ballots perfectly.
Took a fresh sheet of Bounce and wiped down the aluminum guide plate and both plastic guides. Ballots whistle through like ... through a goose. The copier technicians would experience a static charge in the feed cassette and neutralize it with Bounce or similar product as well as providing a slight lubricant.
Better get McKinney's blessing first though.
