Electrophotographic printing system with external feed of continuous paper web of fanfold type - passed through guide section and subjected to controlled tension

摘要

An electrophotographic printer can operate using continuously fed paper from either an internal (11/1) or external 11/2) stack. The external paper (12) passes over a guide unit (23) and into a channel (21) that connects with rollers (25, 26) maintaining controlled tension as the paper passes over a photosensitive drum (16) in the printing station and aquires a toner image. The paper then passes to a fixing station (18) before being delivered to a magazine. The input of the paper through the guide section is controlled by an actuated unit (33) that maintaines a controlled friction force. Internally the paper passes over a damper. ADVANTAGE - Reliable and damage free paper feed system.
