Patent number: 7255421Abstract: An imaging apparatus includes a carrier housing having an attachment feature, a carrier belt to transmit a translation to the carrier housing in a bi-directional scanning direction; and an interface device interposed between and coupled to both the carrier housing and the carrier belt. The interface device includes a body having a wing and a base. The wing is defined by a span and by a chord length. At least one of the wing and the base is mounted via the attachment feature to the carrier housing. The span extends in the bi-directional scanning direction, and the chord length is substantially perpendicular to the span.Type: GrantFiled: September 27, 2004Date of Patent: August 14, 2007Assignee: Lexmark International, Inc.Inventors: Marc Alan Herwald, Brian Andrew Naro, Bryan Christopher Scharf

Patent number: 7168799Abstract: A printhead carrier includes a body defining a receptacle for receiving a supply cartridge. The body includes a front portion, and a rear portion spaced from the front portion. The rear portion has a latch opening. A cover is provided having a first end configured for pivotal attachment to the front portion of the body. A latch arm has a proximal end attached to the cover. A distal end of the latch arm includes a latch lip. The latch lip engages the latch opening in the rear portion of the body when the cover is in a closed position. A release mechanism is coupled to the rear portion of the body. The release mechanism includes a cam for engaging the latch lip of the latch arm to force the latch lip out of the latch opening when the release mechanism is moved from a latch position to a latch release position.Type: GrantFiled: June 28, 2004Date of Patent: January 30, 2007Assignee: Lexmark International, Inc.Inventors: Michael James Benson, William M. Connors, Brian Andrew Naro

Patent number: 7128391Abstract: An imaging apparatus includes a printhead carrier configured for movement along an X-axis. The printhead carrier includes a carrier housing having a first bearing pocket and a second bearing pocket. The first bearing pocket and the second bearing pocket are spaced apart along the X-axis. A Z-axis passes through a central region of the carrier housing. The Z-axis is substantially perpendicular to the X-axis. A first bearing is configured to be received in the first bearing pocket. The first bearing includes a first curved outer surface having a curve that extends in a direction of the X-axis. The curved outer surface is received in the first bearing pocket to facilitate a rotation of the first bearing in relation to the Z-axis of the carrier housing. A second bearing is configured to be received in the second bearing pocket.Type: GrantFiled: June 30, 2004Date of Patent: October 31, 2006Assignee: Lexmark International, Inc.Inventors: Robert Michael Meadows, Brian Andrew Naro, Bryan Christopher Scharf, Randal Scott Williamson

Patent number: 7021741Abstract: A printhead capping assembly includes a cap holder and a printhead cap. The cap holder defines a cavity and a vent exit. The printhead cap has a base and a lip portion extending from the base. The lip portion defines an open interior region. The base is inserted into the cavity of the cap holder. The base includes a serpentine channel extending from the open interior region to the vent exit of the cap holder.Type: GrantFiled: November 21, 2003Date of Patent: April 4, 2006Assignee: Lexmark International, Inc.Inventors: Charles Stanley Aldrich, Jeffrey Ray Ehlert, Martin Alan Johnson, Daniel Robert LaBar, Robert Michael Meadows, Brian Andrew Naro

Patent number: 6695426Abstract: A method is provided to reduce vertical banding defects in an ink jet printer. The method includes the steps of identifying a disturbance frequency of a disturbance source; identifying a natural frequency of a printhead carrier system; correlating the disturbance frequency of the disturbance source and the natural frequency of the printhead carrier system to a base carrier velocity; selecting a first carrier velocity for printing in a first direction, the first carrier velocity being different from the base carrier velocity; and selecting a second carrier velocity for printing in a second direction, the second carrier velocity being different from the base carrier velocity and different from the first carrier velocity.Type: GrantFiled: February 11, 2002Date of Patent: February 24, 2004Assignee: Lexmark International, Inc.Inventors: Marc Alan Herwald, Michael Anthony Marra, III, Randall David Mayo, Brian Andrew Naro, Barry Baxter Stout

Patent number: 6481829Abstract: A manually actuated spring loaded latch mechanism for releasably securing a printhead cartridge in a carrier of an ink jet printer. A latch cover engages the printhead cartridge and is secured by an actuator. Depressing the actuator releases the latch cover, which is spring biased to an open position. Further movement of the actuator lifts the printhead cartridge.Type: GrantFiled: September 18, 2001Date of Patent: November 19, 2002Assignee: Lexmark International, Inc.Inventors: Thomas Allen Bailey, Brian Andrew Naro, Herman Anthony Smith
