Patents by Inventor Daniel J. Magnusson

Daniel J. Magnusson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7778589
    Abstract: A method and apparatus for adjusting the print area by positioning a sheet in an imaging device utilizing length data from a prior sheet. A first sheet length is measured and thereafter utilized to determine the print zone for a subsequent sheet.
    Type: Grant

    Date of Patent: August 17, 2010

  • Patent number: 6749192
    Abstract: A media feed mechanism includes a picking device, a first feedroller and a second feedroller. The picking device picks a sheet of media from a media source. The first feedroller moves the sheet of media along a feed media path. During a skew correction phase, the first feedroller rolls in a forward direction feeding the sheet of media forward and the second feedroller turns in a reverse direction preventing the sheet of media from progressing past a nip of the second feedroller. This results in skew correction. After skew correction is performed, the second feedroller turns in the forward direction advancing the sheet of media for printing.

  • Patent number: 6682167
    Abstract: A method for reducing a servicing noise is provided. In a measuring action, a servicing position is measured using a full pushing force of an actuator applied to a service station. In a disengaging action, the actuator is disengaged from the service station. In a reducing action, the pushing force is reduced to a minimum value. In an engaging action, the service station is engaged with the actuator. In a monitoring action, a position of the actuator is monitored during the engagement. In a comparing action, the actuator position is compared to the stored servicing position. In an increasing action, the pushing force is increased for future engagements if the servicing position has not been reached. A printing mechanism configured to employ such a method is also provided.

  • Patent number: 6669323
    Abstract: Resting position error recognition for an ink-jet, translational-type, service station mechanism. Service station drive mechanism binding due to hard stop impact is compensated for by calculating a difference between when the drive mechanism stops and when a predetermined velocity change was first recorded. In a more sophisticated embodiment, noise filtering is employed to improve accuracy with increasing number of uses of the service station mechanism.
