摘要:
Greater throughput is possible by using wider print swaths in each traverse across printing media. Multiple print cartridges are mounted to be offset from each other in the media scan direction (X-axis). The amount of offset is adjustably varied by selective on/off control of individual printing elements as well as by relative mechanical movement of the print cartridges.

Apparatus and techniques are disclosed for aligning the operation of the ink jet printhead cartridges of a multiple printhead ink jet swath printer that includes a print carriage that is movable along a horizontal carriage scan axis, (b) first and second ink jet printhead cartridges supported by the movable carriage for printing onto a print media that is selectively movable along a vertical media scan axis, and (c) an optical sensor supported by the movable carriage. Correction of misalignment along the media scan axis is performed by adjusting the position of the nozzle array of one printhead cartridge relative to the position of the nozzle array of another printhead cartridge along the media scan axis. A movable printhead is supported on the print carriage of the printer and is moved relative to the carriage by a rotatable cam that is supported by the carriage fixedly attached to a cam lever. The cam is rotated by movement of the printhead carriage relative to a actuator arm that is selectively positioned in or out of the path traversed by the cam lever pursuant to movement of the printhead carriage. In particular, the cam is rotated by the movement of the carriage while the cam lever is engaged against the actuator arm.

A thermal head reading/writing device includes a thin-film transistor element which may be switchably operated for printing in response to the variation of a signal voltage applied to a gate electrode.

This disclosure is concerned with a novel digital multi-point recorder that is microprocessor-controlled and enables impact printing from in back of the recorder paper to provide a front visible flat print-out of pages of on-line running summary data suited for operator viewing in industrial and similar locations, and providing a record for direct use in reports and logs.
摘要:
An improved print mechanism for a plural-function recorder having a single record receiver includes a continuously orbiting rod and a plurality of print wheels each of which has a plurality of marking elements on the periphery thereof. The orbiting rod operates successively and repetitively to effect joint step-bystep angular synchronous adjustments of said print wheels to bring each of said marking elements, in turn, into a position for marking said record receiver. The orbiting rod also actuates said print wheels, when so adjusted, into and out of firm marking engagement with said record receiver. Recording in different modes selectively may be effected by a manual adjustment which permits relative axial displacement of said print wheels and thereby printing by one only or both of said print wheels continuously, or by one continuously and the other intermittently.
