摘要:
A position transducer system is disclosed for a limited rotation motor that includes an illumination source that directs illumination toward an illumination reflector that rotates with a rotor of the limited rotation motor, and a plurality of detector areas adjacent the illumination source for receiving modulated reflected illumination from the illumination reflector.

Disclosed is a jet printing method, which includes firing printing fluid drops and deflecting them. The drops are then deflected again in a second direction, which can allow them to be deposited in a collimated swath. Also disclosed is dynamically adjusting the deflection to achieve a dynamic swath density and/or a dynamic swath width.

A jet printer is disclosed that features, in one general aspect, a plurality of detectors responsive to attributes of fluid drops emitted by a jet printing nozzle, and a statistical processing module responsive to an output of each of the detectors. Also disclosed is a printer with a first non-invasive printing fluid drop detector operative to detect printing fluid drops emitted by the jet printing nozzle during flight without significantly affecting their output trajectories, and an actuator operative to change an effective spatial relationship between the detector and the nozzle. Further disclosed is a printer with a first printing fluid drop detector operative to detect printing fluid drops emitted by a jet printing nozzle, and a first fluid drop impingement detection element operative to derive information about printing fluid drops emitted by the nozzle by interfering with their trajectories.

Disclosed is a continuous ink jet printing apparatus and related method. The method can feature deflecting a first stream of ink drops to create a first deposition pattern, and deflecting a second stream of ink drops to create a second deposition pattern that overlaps at least in part with the first deposition pattern. Print density can be adjusted for drops corresponding to a region of overlap between the first and second deposition patterns.

Disclosed is a continuous ink jet printer that includes an ink jet printing nozzle for a first color positioned to deposit ink drops on a substrate, and a deflection element located proximate an output trajectory of the first ink jet printing nozzle and operative to deflect the ink drops in a swathed pattern as they are deposited on the substrate by the first ink jet printing nozzle. A second ink jet printing nozzle is also provided for the first color positioned to deposit ink drops on the substrate, and a second deflection element is located proximate an output trajectory of the second ink jet printing nozzle and operative to deflect the ink drops in a swathed pattern as they are deposited on the substrate by the second ink jet printing nozzle. Interleaving logic is operative to provide interleaved print data to interleave at least one deflected drop from the first ink jet printing nozzle with a plurality of deflected drops from the second ink jet printing nozzle in parallel offset rasters.
摘要:
A lead screw coupling that includes two universal joints. The first joint is operatively connected between a first member that includes a mounting site for coupling to a lead screw nut, and a second member. The second joint is operatively connected between the second member and a third member that includes a mounting site for coupling to a movable printer carriage. In a preferred embodiment the universal joints and the members are all defined by a plurality of slanted planar slots that are each cut along a plane that is tilted with respect to an axis of rotation of the lead screw.
