A sheet conveying device includes a first roller, a second roller, and a controller. The first roller is configured to rotate in a forward direction for sheet conveyance along a sheet conveying direction. The second roller is disposed downstream with respect to the first roller in the sheet conveying direction and configured to rotate in a forward direction along the sheet conveying direction and in a reverse direction. The controller is configured to control the second roller to rotate in the reverse direction at a timing when a leading end of a sheet that is nipped and conveyed by the first roller reaches a nip of the second roller.

A method for use in guiding a hand-operated printer positioned over a print medium includes determining a position of the hand-operated printer relative to the print medium; and generating on a display screen a virtual image of at least a portion of an area under the hand-operated printer, corresponding to the position of the hand-operated printer.

Guiding a hand-operated printer

Methods and apparatus include a handheld printer manipulated by an operator to print an image on a media. An inkjet printhead and two position sensors front one another in a triangular configuration thereby providing a large printable area compared to the prior art. A frame commonly mounts the printhead and sensors and is biased to keep an acceptable paper to printer gap during use. A forward opening door accepts the printhead before printing.

Handheld printer configuration

An improved handheld printer includes projectors to project images of the various page content that remains to be printed on the page. By providing this visual indication of locations of the page that remain to be printed, the projectors assist the user in achieving full coverage of the page when moving the handheld printer across the page. The projectors emit a narrow beam of light that can be rapidly scanned, with the assistance of micromirror-based optics, over points composing an area on the page to create a visual image to guide the user along the page. The projectors can be used to project an actual image of the page content to be printed. Alternatively, the projectors can project signals or other meaningful information onto the page that provide instructions to the user or point the user towards void areas that have been missed.

Methods and apparatus include a handheld printer manipulated back and forth by an operator during use to print an image on a media. The media includes reference indicia upon which users maneuver the printer whenever a location of the printer is unknown or needs updating or validating. A controller of the printer correlates the location of a printhead to the image and when lost communicates to a direction indicator to provide user notification of where to move the housing to reacquire the location. Embodiments of the reference indicia include guide and location patterns, with the guide pattern pointing to the location pattern. Other indicia include related tick marks of substantially equal size and shape with substantially equal spacing there between. Supply items for applying on the media include a substrate with reference indicia thereon that matches stored reference indicia in the printer.

A hand-held micro-fluid ejection device for ejecting a fluid onto a substrate surface in a plurality of physical orientations between the ejection device and a substrate surface, and methods for controlling the geometric accuracy of printing using a hand-held printing apparatus. Various spatial and dynamic orientations of the ejection device are measured, such as rotation angle, yaw angle, and velocity and acceleration vectors. Threshold limits are established for the orientations and printing is disabled if the measured values exceed the threshold limits.

An apparatus includes a multi-format memory card drive having a multi-format memory card slot configured to receive any of a plurality of memory cards having a corresponding plurality of memory card formats. At least one of the plurality of memory cards has a memory card format that is different from another memory card format of the plurality of memory card formats. A bezel is configured for installation over the multi-format memory card slot. The bezel is configured to select a subset of the plurality of memory card formats that can be received by the multi-format memory card slot of the multi-format memory card drive.

An electronic wireless communication system includes an electronic device with a plug-in circuit card. The plug-in circuit card includes a wireless radio circuit and at least one on-board coaxial connector coupled with the wireless radio circuit. An antenna card includes at least one antenna and at least one on-board coaxial connector. At least one of the on-board coaxial connectors on the antenna card is coupled with a corresponding antenna. Each on-board coaxial connector on the antenna card is also coupled with a mating on-board coaxial connector on the plug-in circuit card.
