  • Patent number: 10442219
    Abstract: Systems, methods, and devices for mitigating print head dry out. In an example embodiment, a system can be implemented, which includes an arrangement of cross rollers and a registration transport for transporting one or more sheets for printing, and a steering mechanism that drives the sheet(s) into the opposing registration print edges of print heads on the registration transportation, wherein the cross rollers only engage when the sheet is being registered to the appropriate edge of the print heads, thereby allowing the print heads to be exercised prior to drying out. When one or more of the sheets are out of the nip, the nip disengages, thereby allowing the next sheet to be stirred on the opposing edge of the registration print heads. The opposing registration print heads comprise an inboard registration edge and an outboard registration edge.

  • Patent number: 9708145
    Abstract: A first roller is driven, by a conveying motor rotating in a normal direction and in a reverse direction, to rotate in a forward direction and in a backward direction, respectively. The first roller and a second roller convey a sheet in a conveying direction by rotating in the forward direction. The transmission unit transmits a driving force of the conveying motor to the second roller and includes a first rotary member. The transmission unit has such play that when the conveying motor is switched from rotation in a normal direction to rotation in a reverse direction, rotation of the second roller in a backward direction is delayed by a predetermined time period from rotation of the first roller in the backward direction. The predetermined time period is greater than a time period corresponding to one tooth of the first rotary member.

  • Publication number: 20130051890
    Abstract: Embodiments described herein are directed to characterizing a media curler for a printing. Test curls can be imposed on media having input curls with known input values using a media curler to be characterized. The media curler can impose the test curls based on curler settings of the media curler. Resulting output values from an interaction between the test curls and the input curls can be measured and the curler settings can be characterized based on the known input values and the resulting output values so that the media curler can be configured to respond to incoming media having a known input curl by applying curler setting to achieve a desired output curl.

  • Patent number: 8376640
    Abstract: The present invention prevents density irregularity from appearing in a print result and to thereby improve image quality by controlling a motor so that the rotational speed of a drive shaft that feeds printing media is constant. The present invention provides a printing media feeding apparatus including a feeding section that includes a motor, a drive transmission mechanism which transmits a driving force of the motor, and a drive shaft to which the driving force is transmitted by the drive transmission mechanism. The drive shaft is rotated to feed the printing medium. A detection section is provided having at least a portion secured to the drive shaft and the detection section determines the rotational speed of the drive shaft and a controller controls the motor based on an input from the detection section so that the rotational speed the of the drive shaft is constant.

  • Patent number: 8289554
    Abstract: Designation of paper and an operator as intended by an MIS while maintaining automation of job processing was not possible, since management of expendables in a POD device and management of performance information by the MIS were not coordinated. In view of this, the MIS acquires usable print sheet information including division management information from the POD device, and, based on a designation of paper designated by a job and a designation of paper associated with an operator relating to the job, selects appropriate paper that the operator is able to use, from the print sheet information provided by the POD device.

  • Patent number: 8277039
    Abstract: An inkjet printer prevents the paper from lifting away from the platen when the suction action of the platen is stopped, and thereby prevents paper jams and other printing problems. The printer 1 conveys the printing paper 12a while holding the paper 12a to the surface of the platen 19 by a suction mechanism 50. After the automatic paper cutting operation is completed, the leading end part 12b of the printing paper 12a is retracted from the cutting position B to the printing start position A on the platen 19, and the printer 1 waits for the next print job with the printing paper 12a held against the platen 19. When a power conservation mode or power off mode is entered, the control unit 61 of the printer 1 advances the leading end part 12b of the printing paper 12a from the printing start position A to the cutting position B so that the paper is held by the downstream-side paper feed roller 34 and pressure roller 35, and then stops the power supply to the suction mechanism 50 of the platen 19.
