Paper Path of an On-Line Computer-Output Printer

by R. G. Svendsen
This paper describes the development of a paper handling system designed to move paper at a speed of 81 cm/s in the IBM 3800 Printing Subsystem. During the development of the printer a number of unique problems arose from the interaction among paperline components. The various approaches and solutions to these problems, including paper path alignment, character stretch, registration within the fuser, and path error detection, are discussed and illustrated.
