Patent number: 5842801Abstract: A method and a device for adjusting the printing position of a printer head. When a recordable medium having a greater thickness than that of a standard cut sheet of letter size paper is inserted in an electrophotographic apparatus, it is often necessary to increase the distance between the top recordable medium in the paper supply tray and the paper input port in the electrophotographic apparatus to allow a greater number of thick sheets of recordable medium to be loaded. One method of increasing the distance is to rotate a guide panel into a position that abuts the electrophotographic apparatus and increases the distance between the paper supply tray and the paper receiving port. Unfortunately, this causes the printer head to require adjustment, as the horizontal positioning of the printable medium fed into the printer has changed. This inventive method and device uses a sensor to determine when the guide panel has been rotated and automatically adjusts the printer head's position.Type: GrantFiled: September 10, 1997Date of Patent: December 1, 1998Assignee: SamSung Electronics Co., Ltd.Inventor: Ho-Suck Myung

Patent number: 5823693Abstract: A gapless label media which can be carried by a liner or be linerless. Apparatus is also disclosed for printing on and applying resultant labels which are staggered laterally across the media width. In an embodiment of the invention, the label printer comprises a printhead for printing on the media, a sensor sensing the leading edge of each first label at a known distance from the printhead and a drive system moving the plurality of labels from a position of the sensor to a pre-established print position under the printhead. In another embodiment of the present invention, in which there may be lateral drift of the labels, the sensor senses along a path having a width greater than a maximum amount of lateral drift of the plurality of labels. Alternatively, plural sensors may be utilized to detect plural paths through the labels to detect lateral drift of the labels, or to detect alternating ones of the labels.Type: GrantFiled: March 27, 1997Date of Patent: October 20, 1998Assignee: Intermec IP Corp.Inventors: Thomas A. Henderson, Thomas A. Sweet, Joel A. Schoen

Patent number: 5810492Abstract: A printer and a print start method for a printer allows printing to be started at a desired position reliably even if the sheet to be printed upon is shorter than a standard length. The print start method includes determining the relative size of the sheet to be printed upon and then starting a print operation on a sheet by a print head after a sheet feed roller has released the sheet to be printed upon if the sheet being printed upon has a relatively long or standard length, and starting a print operation on a sheet by a print head before the sheet feed roller has released the sheet to be printed upon if the sheet being printed upon has a relatively short length.Type: GrantFiled: May 23, 1996Date of Patent: September 22, 1998Assignee: Seiko Epson CorporationInventors: Takashi Akahane, Shigeki Hayashi

Patent number: 5803635Abstract: Linerless media for labels is visibly or invisibly marked along its length with marks or small holes to indicate motion marks and/or position marks related to pre-printed label information. The marks are used to properly position pre-printed label information with respect to a printer printhead. The marks can also be used to detect critical speeds of the media that can cause problems such as standing waves or poor print quality from the printhead. The marks are also used to position and print on linerless media being pulled by hand through a printer having no drive motor.Type: GrantFiled: May 4, 1995Date of Patent: September 8, 1998Assignee: Intermec CorporationInventors: Pixie Ann Austin, Cathy Aragon

Patent number: 5772343Abstract: A metering roller and feed guide are included in a desktop printer between a first roller and a print zone. During first side printing, a media sheet is fed along the first roller and directed by an upper feed guide over the refeed guide to a second roller. The metering roller feeds the media sheet through the print zone. As the trailing edge approaches a metering pinch line, the metering roller stops. After a drying time, the second roller reverses direction moving the media sheet back toward the refeed guide. The refeed guide blocks the original path and directs the media sheet toward a repick guide and the first roller. The media sheet is fed onto the first roller for second side printing. In one embodiment the media sheet is wrapped around the first roller and unwrapped into the input tray during the refeed process to accommodate long media sheets.Type: GrantFiled: June 30, 1997Date of Patent: June 30, 1998Assignee: Hewlett Packard CompanyInventors: Robert K. Beretta, Paul W. Martin, Thomas E. McCue, Jr., Thomas W. Ruhe

Patent number: 5767892Abstract: 278 An image recording apparatus, which records an image on a recording medium by performing a sub-scan operation by conveying the recording medium by a predetermined amount upon completion of each main scan operation of a recording unit, is disclosed. The apparatus stops a convey operation of the recording medium after a first image is recorded on the recording medium. When a recording start command is generated within a predetermined period of time after the convey operation is stopped, a re-convey operation of the recording medium is started in response to this command, and a second image is recorded by the recording unit on the recording medium on which the first image is recorded. When the recording start command is not generated within the predetermined period of time, the recording medium on which the first image is recorded is automatically ejected.A plurality of images can be synthesized on a single recording medium before the medium is ejected without using a large-capacity memory.Type: GrantFiled: January 19, 1993Date of Patent: June 16, 1998Assignee: Canon Kabushiki KaishaInventor: Fumio Mikami

Patent number: 5730533Abstract: A duplex printing system and a printing method which enables printing of the second side of substrate in any desired order is provided. The printing system includes a printing unit, a reader and a processing unit. In the first pass, the printing unit receives a digital representation of a first image and at least one machine readable code and prints the first image and the machine readable code on a first side of a printing substrate. In the second pass, the reader identifies the printed machine readable code, preferably a bar-code, and provides it to the processing unit. The processing unit provides the digital representation of a second image associated with the machine readable code to the printing unit for printing a second image on a second side of the printing substrate, preferably, but not necessarily, in an orientation which is generally similar to the orientation of the printed first image and in registration therebetween.Type: GrantFiled: October 31, 1995Date of Patent: March 24, 1998Assignee: Nur Advanced Technologies Ltd.Inventors: Amir Noy, Avi Feinschmidt

Patent number: 5725321Abstract: A system for indicating fault conditions in an automated banking machine includes a journal printer (12). The journal printer is supplied with paper from a paper supply roll (16). The paper supply roll is supported on a spindle (22). The spindle is engaged to the paper roll by spring arms (60). The spindle further includes a spring loaded retainer member (42) and a flange portion (34) which act to apply a drag force on the spindle to prevent overrunning. The spindle also has an encoder member (40) thereon. Rotation of the encoder member is sensed by an opto-electrical detector (70). A diameter of the paper supply roll is sensed by a second opto-electrical detector (78) positioned between the spindle and the printer. The detectors are connected to an electronic circuit (74) including a processor (76). Fault signals are generated by said electronic circuit responsive to said detectors sensing conditions representative of paper jam, paper low and paper out conditions.Type: GrantFiled: December 7, 1995Date of Patent: March 10, 1998Assignee: InterBoldInventors: Jeffrey A.
