TROUBLESHOOTING
Feeding, bursting, and stacking problems are usually due to improper adjustment of machine to forms or due
to a non-standard or defective form.
Most problems fall into one of three categories: Electrical, Mechanical, or Form Flow. Electrical troubles are
USUALLY obvious because machine will not run or respond in a normal manner to its controls.
Mechanical problems are usually accompanied by noise, slippage, tearing, or binds. If a form fl ow problem is
present, jamming, mis-stacking, or intermittent form damage will occur. Problem should be diagnosed to one
of three categories, before proceeding to pinpoint problem. Best approach is a logical elimination of possible
malfunctions.
