ABSTRACT:
A modular bidirectional tractor feed assembly having its own platen, which is substituted for the platen normally in the printer, is installed on the printer as a single unit using projections on the side platen of the feed assembly. Adjustments are performed on the assembly during manufacture to assure proper alignment of elements to provide error-free feeding of record material and properly aligned printing thereon. The assembly includes mechanism to provide positive assist in loading the record material, mechanism to prevent the perforations in the record material from becoming stuck on the drive pins when the record material leaves the feed mechanism, mechanism for easily locking and unlocking the feed mechanism in position to accommodate various widths of record material and mechanism to easily adjust the tension in the drive pin carrying chains of the feed mechanism.
