摘要:
A printer has a print head arranged to jet molten ink onto a surface, a transfix surface arranged to provide the surface for the print head, the transfix surface having a core and an outer shell of a predetermined grade of aluminum arranged on the core, the outer shell forming the surface for the print head. The printer also has a transport subsystem to transport a print substrate past the transfix surface such that the molten ink transfers from the transfix surface to the print substrate.

A method for performing duplex printing enables increased throughput in an indirect printing system. The method includes measuring a coverage parameter for image data to be printed, and transforming operation of the printer from a first printing process timing sequence to a second printing process timing sequence in response to the coverage parameter exceeding a predetermined threshold.

A scratch-off document may include a substrate bearing a toner image and a scratch-off layer covering the printed content. The scratch-off layer may include a mass of a first solid ink and a mass of a second solid ink printed over the first solid ink in a distraction pattern. The toner image is formed of a toner that adheres to the substrate, while the scratch-off layer is made of a wax-based or other solid ink that may be removed from the substrate by scratching without removing the toner image. The distraction pattern includes varying pile heights that distract a viewer from any pile height variations that may exist in the toner image.

摘要:
A method of operating a printer produces duplex images with improved throughput. The method monitors the position of an area of pressure roller that carries release agent and synchronizes a media transport to insert a media sheet into a nip formed with the pressure roller so the release agent on the pressure roller exits the nip as the leading edge of the media sheet enters the nip. The circumference of the pressure roller is an integral number times the length of the media sheet plus inter-document gap.

Multi-stage fixing systems for fixing toner to a substrate, printing apparatuses and methods of fixing marking material to a substrate are provided. An exemplary embodiment of the multi-stage fixing systems includes a softening device for softening toner applied to a substrate by a marking device; and a fixing device for fixing the softened toner to the substrate. The fixing device includes a first fixing member including a first surface; a first thermal energy source for actively heating the first surface; and a second fixing member including a second surface, the first surface and the second surface form a fixing nip at which the substrate with softened toner is received. The first fixing member and the second fixing member are operable to apply heat and pressure to the substrate and softened toner received at the fixing nip to fix the toner to the substrate.
摘要:
A printing apparatus includes a printing station, including at least one printhead for applying phase-change ink to the substrate, and a backing member disposed on an opposite side of the substrate substantially opposite the printhead, the backing member causing the substrate to reach a predetermined ink-receiving temperature.
摘要:
A cleaning system for cleaning an imaging surface moving in a process direction, including: an abrading brush for uniformly abrading the imaging surface to remove laterally conductive deposits that lead to lateral charge migration therefrom, the abrading brush includes a core defining a core length and having fibers extending outwardly therefrom, the fibers include abrasive particles attached thereto.
摘要:
An apparatus which controls the dispensing in mixing of marking particles into a developer unit used in an electrophotograhic printing machine. In particular, the present invention is directed to a developer housing that includes a variable speed mixing apparatus for improving material life and performance. The quantity of marking particles required to reproduce the document is predicted and the dispensing and mixing of marking particles controlled in response thereto.
