Is your folding machine missing folds, folding incorrectly, or shifting positions? The photoeye is faulty—clean or replace it to fix the problem quickly.

Dirty photoeyes and reflectors cause malfunctions. Turn off the power, and gently wipe the photoeyes on both sides of the feed inlet and their reflectors with a dry flannel. Don’t use a wet cloth to avoid damaging parts. Test the machine—if the photoeye light flashes normally, it’s fixed.
