Appl. No.:

09/626465

Elias Panides - Whitestone NY

Assignee:

International Classification:

B41J 2385

US Classification:

347116, 347235

Abstract:

Color electrophotographic printers having latent image positions synchronized with start-of-scan signals. A laser source projects a laser beam onto a multifaceted rotating polygon that sweeps that beam in a scan line across a moving photoreceptor. A start-of-scan detector produces start-of-scan signals when the laser beam is in position to write a scan line. A belt sensor produces belt signals when indicia on the photoreceptor passes a reference position. A controller receives the belt signals and the start-of-scan and then adjusts the photoreceptors rotational velocity such that the belt signals are an integral multiple of the start-of-scan signals. To reduce the impact of drive roller eccentricities on belt signal to start-of-scan signal timing, the perimeters of photoreceptor roller elements are sub-multiples of the photoreceptor length.

International Classification:

G03G 1500

US Classification:

399165, 19881003, 198814, 399162

Abstract:

In a printing system in which a rotatable print image bearing belt is mounted on at least one axial belt roller, and the belt must be maintained in a desired substantially consistent lateral registration to maintain image quality, the lateral misregistration of the belt is sensed and a low and substantially constant lateral positional corrective force is applied to the belt in response to the sensing of the lateral misregistration in one of the two directions axial of the axial belt roller for at least one complete rotation of the rotatable print image bearing belt, the low and substantially constant transverse corrective force having a force level sufficient to provide the desired substantially consistent lateral registration of the print image bearing belt.

US Classification:

347102, 219216, 1014241, 34618, 34620, 34638, 34658

Abstract:

A dryer assembly for drying a liquid ink image formed on a substrate comprising a housing defining a portion of a sheet moving path; a plenum positioned within the housing, the plenum including air flow and outlet means contiguous to the plenum permitting forced air to exit the plenum, the outlet being in the form of a plurality of moving openings adapted to direct flowing air through the openings to the liquid image, the openings moving relative to the image; and a substrate transport device for moving the substrate carrying the liquid ink image on a front side thereof through the housing and under the plurality of moving openings. The dryer assembly has particular use in an ink jet printing system.

International Classification:

G03G 15/20

US Classification:

399320, 219216, 399 92, 399335

Abstract:

This is a pre-heater system especially useful in an electrostatic marking apparatus. It is used to heat the toner and paper (media) prior to the paper entering the conventional fuser station. Using this pre-heater increases fusing productivity (ppm), widens media latitude and/or extends fuser member life for a given fuser system. It also dramatically improves uniform heat transfer and paper handling problems encountered in prior art preheat fusing assemblies. The preheater is used together with the conventional fuser stations used today in electrostatic marking systems.

International Classification:

G03G 15/14

US Classification:

399 93

Abstract:

An image forming device includes marking material dispensers for disposing an image on an imaging drum surface. The image forming device further includes plural particle removal devices comprising first and second particle removal devices coupled to a vacuum source. The first particle removal device includes a first vacuum port positioned as close as possible to an included image transfer site. The second particle removal device includes a second vacuum port positioned as close as possible to the marking material dispensers. The first and second vacuum ports are positioned proximate to the imaging drum surface to provide respective first and second air flows.

US Classification:

347 29

Abstract:

An apparatus is used with an ink jet print head in an ink jet printer. The apparatus includes a print head protector that surrounds a print head. A substantially continuous slot is provided along a perimeter of the bracket and a filter is located in the substantially continuous slot. An inlet in fluid communication with the substantially continuous slot enables a positive pressure air supply to be coupled to the inlet. The air entering the inlet flows through the filter in the slot and the filtered air flows outwardly away from the print head.

US Classification:

347 70

Abstract:

The present application is directed to piezoelectric actuator devices. One embodiment of a piezoelectric actuator comprises a chamber diaphragm having a major surface. A piezoelectric transducer is positioned on the major surface of the chamber diaphragm. The piezoelectric transducer has a major surface having a first dimension which is smaller than a corresponding second dimension of the major surface of the chamber diaphragm, so that the piezoelectric transducer underlaps the chamber diaphragm. The underlap ratio of the first dimension to the second dimension ranges from about 0. 70 to about 0. 99.
