A method for producing a printer wherein tractor drives move a length of fan-fold, continuous-form paper upwardly from a stacked source thereof, through a print mechanism, across a paper directing assembly and then downwardly to refold onto an output stack, the method including steps for detecting misfolds of the fan-fold paper in the printer.

Producing a continuous-forms printer with a paper misfold detector

Tractor drives of a high speed printer move a length of continuous-form paper longitudinally up from a box of fanfold stacked paper, through a print mechanism, across paper directing means, and downward to refold onto a fanfold stack. A misfold detector is positioned at the paper directing means to sense the jumble of paper caused by misfolding prior to jamming of paper movement through the tractor drive to prevent damage to the paper, complex restarting procedures, or data loss.
