Abstract:

A modular high speed printing system for printing alphabetic and numerical information upon individual items or documents fed individually or in series through the modules. A feeder module performs accounting functions as to the number of documents processed, provides multiple or single mode document feeding and is adjustable to accommodate different size documents. The system also includes one or more printing modules for printing machine readable repetitive data, machine readable consecutive data, repetitive alphanumeric information and consecutive numeric information. A document receiver module adjustable to different size forms is also provided. The printing modules employ common document drive systems including an adjustable document end stop to permit horizontal placement of the information on the document. Vertical positioning of the information on the document is accomplished by means of adjusting the print mechanisms. The individual modules can be selected for operation in active or bypass modes and single cycle or flow feeding modes.
