The present specification discloses a fax machine with routines for generating more than one cover sheet for a single fax job, where the cover sheets are different. The cover sheets are generated by providing a display which includes a first recipient input area for identifying a first recipient and a second recipient input area for identifying a second recipient and a first comment input area for inputting a first comment associated with the first recipient and a second comment input area for inputting a second comment associated with the second recipient.

Multi-recipient facsimile communications

A printing apparatus includes non-transparent doors and/or drawers on a body of the printing apparatus. The non-transparent doors and drawers allow access to internal areas of the body of the printing apparatus. A processor is within the body of the printing apparatus, and the processor controls actions of the printing apparatus. Also, at least one internal graphic user interface display is within the body of the printing apparatus. The internal graphic user interface display is operatively connected to the processor, and the internal graphic user interface display is positioned to be observable only when the non-transparent doors and drawers are open.

Printing device having internal graphic user interface display

A printing system and apparatus assembly that incorporates a transparent platen for supporting and scanning a first image therethrough. The transparent platen includes a translucent display layer having an array of light devices that comprise organic light emitting diodes. A user interface of the system is coupled to the transparent platen with a processor. Based on input and/or data provided at the user interface, an image is displayed through the platen with the display layer.

A paper feed system for use in a printing apparatus that detects multi-feeds and separates all sheets while allowing a single sheet to continue into the machine includes a nip with a drive roller for feeding sheets. A reversible pressure roller downstream of the drive roller is connected to a motor, but idles in the direction of the paper feed in normal operation. When a multi-feed is detected, the motor is turned ON and the reversible pressure roll actuated by a controller. The reversible pressure roller has more friction with the sheet in its contact than the friction between sheets. This drives the sheet in contact backwards.

Dual nip multi-feed detection and control system

A paper feed system for use in a printing apparatus that detects multi-feeds and separates all sheets while allowing a single sheet to continue into the machine includes a nip with a drive roller for feeding sheets. A reversible pressure roller downstream of the drive roller is connected to a motor, but idles in the direction of the paper feed in normal operation. When a multi-feed is detected, the motor is turned ON and the reversible pressure roll actuated by a controller. The reversible pressure roller has more friction with the sheet in its contact than the friction between sheets. This drives the sheet in contact backwards. This sheet can be diverted to a separate paper path using a gate mechanism and, if desired, fed back into the feed path.

Multi-feed detection and control system

An illuminator system includes an illuminator array positioned adjacent to an image bearing surface, a light diffuser, and a linear sensor array. The light diffuser includes a plurality of rounded lenslets having convex or concave configuration positioned between the illuminator array and the image bearing surface. The rounded lenslets are positioned with respect to the illuminator array to receive the light beams emitted by the illuminator elements and to diffuse the light beams being transmitted to the image bearing surface in the linear direction of the illuminator array. Each of the rounded lenslets has a textured surface with a plurality of indentations. Each of the indentations is configured to randomly diffuse the light beams being transmitted to the image bearing surface.

A method and apparatus that validates a hologram by scanning the hologram at multiple angles is disclosed. The method may include scanning a document containing the hologram at a first angle to create a first image, scanning the document containing the hologram at a second angle to create a second image, determining whether the hologram is valid, and sending the validity determination to a user interface for display to a user.

Method and apparatus for validating holograms

A web cleaning system for a fuser system includes a web which is biased into contact with a rotating cylindrical member, such as a fuser roll, as the fuser roll is rotated about its axis of rotation. A lateral displacement system displaces the web, relative to the cylindrical member, in a direction parallel to the axis of rotation of the cylindrical member. In this way, regions of the web which have become contaminated with collected toner are shifted laterally, thus avoiding oversaturation of the web.

An illuminator system comprising an illuminator array positioned adjacent to an image bearing surface, the illuminator array comprising a plurality of discrete illuminator elements spaced in a linear arrangement, the illuminating elements each being configured to emit a light beam for transmission to the image bearing surface at an incidence angle; a light diffuser comprising a plurality of rounded lenslets having convex or concave configuration positioned between the illuminator array and the image bearing surface, the rounded lenslets being positioned with respect to the illuminator array to receive the light beams emitted by the illuminator elements and to diffuse the light beams being transmitted to the image bearing surface in the linear direction of the illuminator array; and a linear sensor array comprising a plurality of sensors positioned adjacent to the image bearing surface such that the light beams reflecting off the image bearing surface at a reflectance angle are received by the sensors.

A fuser apparatus includes first and second rolls rotatably mounted parallel to and in contact with each other to form a nip through which print media with a toner image thereon is passed to fuse the image to the print media. A cleaning system is provided for cleaning one of the rolls, such as the fuser roll. The cleaning system includes a rotatably mounted cleaning roll, an outer surface thereof including a pile. A flicker bar is arranged to detach toner from the pile.

Cleaning system for a fuser apparatus

A fusing apparatus includes a fuser roll and a pressure roll which define a nip therebetween. Two heating elements heat the fuser roll. One of the heating elements is configured for heating a first portion of the fuser roll while a second of the heating elements is configured for heating a second portion of the fuser roll. The second portion of the fuser roll is axially spaced from the first portion. A temperature sensing system monitors a temperature of the fuser roll in a first location and monitors a temperature of the fuser roll in a second location which is axially spaced from the first location. A control system determines an amount of power to supply to the first heating element as a function of the monitored temperatures at the first and second axially spaced locations and determines an amount of power to supply to the second heating element as a function of the monitored temperatures at the first and second axially spaced locations.
