Abstract
A broad swing arm having a finger at its swinging end extends from an axis near a fixing unit to a tractor, overtop and next to a continuous form transport path. Any bulge or buckle caused by a paper jam and forming in the continuous form at any position between the fixing unit and tractor, and across the width of the form, is detected as the swing arm is pushed up at some point along its length, moving the finger away from a sensor monitored by a controller. Printing in the printer is stopped when the sensor detects that the finger has been moved.
