Abstract
A method for applying vacuum force across a width of a web of movable print medium as it moves through a printing system and determining if positions of a pair of adjustable edge seals do not correspond to the width of the movable print medium is disclosed. The method comprises defining a vacuum chamber and using a vacuum source to provide vacuum in the vacuum chamber. Sealing rollers and the adjustable edge seals define an opening in the vacuum chamber. Appropriate response curves from a plurality of response curves for different known print media are selected. First and second signals indicative of the activation level of the vacuum source and the vacuum level in the vacuum chamber are produced. The signals are compared to the response curves to produce an error signal indicating whether the position of the edge seals corresponds to the width of the print medium.
