摘要:
A cleaning system including: a cleaning device for cleaning laterally conductive deposits from the imaging surface; an AC bias member, adjacent to the imaging surface and positioned downstream from the cleaning device; and a power supply for biasing the AC bias member to generate corona that contacts the imaging surface to degrade laterally conductive deposits that lead to lateral charge migration on the imaging surface.
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:
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 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.
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:
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.
摘要:
A solid or phase change inkjet ink incorporating a polar acidic wax is described. The use of polar waxes as an ink additive improves the polarity of the ink and adhesion of the ink to paper. A method for applying the solid or phase change ink incorporating an acidic polar wax additive to form an image is also described.
摘要:
Disclosed herein are curable solid inks which are solid at room temperature and molten at an elevated temperature at which the molten ink is applied to a substrate. In particular, the curable solid inks of the present embodiments comprise low molecular weight amide gellants that impart self-leveling capabilities to the inks. Also disclosed herein are methods for making the amide gellant and the inks comprising the amide gellants.
摘要:
A solid ink composition comprising an amorphous component, a crystalline material, and optionally, a colorant, which are suitable for ink jet printing, including printing on coated paper substrates. In embodiments, the solid ink formulation comprises a blend of amorphous and crystalline components which provides a solid ink with excellent rheological properties and robustness when forming images or printing on coated paper substrates.
