Abstract: A method and device for locking and unlocking a print head assembly along a shaft in an addressing machine. The print head assembly is fixedly mounted on a locking mechanism, which comprises a cylindrical body slideably mounted on the shaft and a cam ring rotatably mounted over the cylindrical body. The cylindrical body has a slot for seating an elongated spline. When the locking mechanism is operated in a locking position, the inner circumference of the cam ring presses the spline against the shaft, preventing the cylindrical body from moving along the shaft. The cam ring has a relief on its inner circumference such that, when the cam ring is rotated to the unlocked position, the spline is partially seated in the relief, thereby reducing the pressure exerted by the spline against the shaft. As such, the position of the print head assembly can be adjusted.

Abstract: A printer (15) for hand-labeling devices (1) has printing bands (57) bearing print types (17). Each band is positively guided around a selector wheel (53) and around a counter-pressure element (55) spaced apart from the wheel. Selected types (17) are set into printing position on the counter-pressure element (55) by rotation of the selector wheel (53). The selector wheel (53) has engagement recesses (60) into which a stop member elastically engages when a printing position is reached, thereby fixing the selector wheel (53), and hence the printing band (57), in the printing position. The stop member is provided as a comb-shaped stop spring (66) having individual teeth or elastic tongues (61a thru 61x), with one elastic tongue being associated with each selector wheel (53).

Abstract: A second printing unit includes a mark detection means for detecting a positioning mark that a first printing unit has formed on a front surface of a web. A control means controls web-transport speed in the second printing unit so that a time difference between a generation timing of a CPF-N signal and a detection timing of the positioning mark becomes constant, and also stores the web-transport speed into a memory. During a subsequent printing operation, a web-transport speed is controlled to be the same as the web-transport speed stored in the memory for a period until a positioning mark is first detected after the printing is started.

Abstract: An inkjet printer, and method of assembling the printer, for printing an image on a first receiver of a first size and on a second receiver of a second size. According to a preferred embodiment of the invention, the first receiver is fed in a first direction and the second receiver is fed in a second direction orthogonal to the first direction. The printer includes an ink jet print head movable in the first direction to print the image on the first receiver in one printing pass and movable to-and-fro in the first direction for printing the image on the second receiver in at least one printing swath. Thus, printing on differently sized receivers is obtained without reorienting the receivers or changing-out the print head to a different size print head.

Abstract: A printer and method for printing indicia on a disk. According to an embodiment of the invention, a printer comprises a plurality of elongate print heads arranged orthogonally with respect to each other about a center axis defined between the print heads. The print heads are capable of printing indicia on a disk having an annular printing area. The disk may be a recordable compact disk or a read-only memory compact disk, if desired. The print heads may be coupled to a rotatable hub centered at the center axis, such that the print heads extend radially outwardly from the hub. A motor is coupled to the hub for rotating the hub, so that the print heads rotate in unison about the center axis as the hub rotates. A controller coupled to the motor and print heads synchronously control operation of the motor and print heads. In this configuration of the invention, the print heads rotate while the disk is stationary.
