A web alignment method and apparatus for a printing system that includes a friction drive, wherein the alignment device provides one or more of the following: a) a stable medium path with reduced web-walk, b) an alignment system that is not sensitive to the mechanical alignment of an upstream device such as a roll unwinder, c) an alignment system having a lower complexity and lower cost than active controlled systems, and d) an alignment system that is compatible with a wide range of media, ranging from lightweight papers (for example 60 gsm) to heavyweight stock (such as 300 gsm) including high weight high gloss coated grades. The alignment device includes an arrangement for supporting the web in an arcuate form between adjustable side guides.

Device and method to feed and align a web with increased web stability for printing

An improved electrostatographic color printing apparatus includes an exposure unit for forming successive electrostatic latent images on the surface of a recording member in the form of an endless belt, a developing station for sequentially developing the electrostatic latent images to form toner images on the belt, and a transfer zone having electrostatic transfer stations for sequentially transferring the toner images from the belt in superposition onto a receptor sheet fed through the transfer stations while in contact with a belt section therein to produce a multicolour duplex image.

Electrostatic color printing apparatus wherein the receptor sheet is

In an imaging system having at least two optically butted CCD sensors disposed in angular relation to each other and onto which light images are projected by means of a light beam splitter, the correct spacial position of the sensors is determined providing the beam splitter with mounting surfaces on which the respective sensors are mounted and the sensors with lateral surfaces, and utilizing mounting members for the opposite ends of each sensor, each mounting member having a base surface and a supporting surface extending in true rectangular fashion thereon. The base surface of each mounting member is adhesively bonded to one of the mounting surfaces of the beam splitter and its supporting surface is adhesively bonded to a lateral surface of a sensor, such bonding being effected after each sensor has been correctly aligned.

Optically butted electro-optical components

An optical scanning apparatus for scanning image information of a document on a document support (D) and a scanning unit (50) being positively guided along a predetermined scanning path; characterized in that said scanning unit has bearing members (30) for making contact with a face of said document or document support and thereby determining the optical distance between that face and said focusing means (10), and in that said unit is mounted so that it is under biasing forces which maintain its said bearing members in running contact with said document or document support during a scanning movement of the unit.
