20140232777 | Method of Using Star Wheel with Adjustable Directional Biaser - A method of printing with an inkjet printer including a printhead, a star wheel located downstream from the printhead, and an adjustable biaser coupled to the star wheel. The method comprises analyzing print data to identify an area of printing to be printed on a sheet of print media that aligns with the star wheel; calculating the density of the printing in the identified area of printing; printing the identified area of printing; determining whether the calculated density exceeds a density criteria, and if so then using the adjustable biaser to lift the star wheel off of the sheet before the printed area of printing reaches the star wheel; advancing the printed area of printing past the star wheel; and using the adjustable biaser lowering the star wheel onto the sheet after the printed area of printing has advanced past the star wheel. | 08-21-2014 |
20140232778 | Star Wheel with Adjustable Directional Biaser - A print media feed system in a inkjet printer, the system has a media feed roll, a star wheel mounted opposing the roll, an adjustable biaser coupled to the star wheel, and a controller coupled to the biaser. The controller varies a magnitude, a direction or a magnitude and direction of a biasing force applied to the star wheel by the biaser. In one form, the biaser comprises a motor driven cam that varies the angular position of a pivotable lever having a star wheel rotatably attached on one end. In another form, a rack and pinion gear assembly is used to vary the biasing force with a star wheel rotatably attached to the rack. In a further form, a solenoid is used to vary the basing force applied to the lever or applied to a star wheel rotatably attached to the end of the shaft of a solenoid. | 08-21-2014 |

20080237966 | Rotating Input Tray for An Automatic Document Feeder Of An Imaging Apparatus - A rotating input tray for an automatic document feeder of an imaging apparatus includes a document tray configured to hold the document and to supply the document to the input of the automatic document feeder in a document feed direction, and a pivot device coupling the document tray to the component of the imaging apparatus, the pivot device providing a document tray axis of rotation, wherein the document tray and the pivot device are configured to permit the document tray to rotate about the document tray axis of rotation between a closed position and an open position, the closed position being adjacent to the input for supplying the documents to the automatic document feeder, and the open position being away from and exposing both the input and the exit of the automatic document feeder. | 10-02-2008 |
20080316549 | Method For Scanning And Processing A Document With An Imaging Apparatus - A method for scanning and processing a document with an imaging apparatus, the imaging apparatus having a scanner with a scan bar, includes operating the scanner to obtain preliminary image data; performing at least one of translating the document across the scan bar and translating the scan bar across the document while operating the scanner; detecting an edge of the document based on a change in the preliminary image data; scanning the document to generate document image data based on the detecting the edge; and processing the document image data based on detecting the edge to generate a scanned image. | 12-25-2008 |
20090085280 | Duplex ADF Mechanism - An duplex auto-document feed mechanism comprises an auto-document feedpath having a simplex feedpath portion and a duplexing feedpath portion in feeding communication with the simplex feedpath portion, the auto-document feedpath has a media input and a media output, an input roller for feeding media disposed at the media input and an exit nip positioned near the media output, a motor driving the input roller and the exit nip, a scanning station disposed along one of the duplex feedpath portion and the simplex feedpath portion, the exit nip having a first position wherein first and second rollers defining the exit nip are closed when receiving media during a simplex feeding procedure and open when a leading edge and trailing edge of media are passing through the exit nip simultaneously, wherein a change of motor direction one of opens the exit nip or closes the exit nip. | 04-02-2009 |
20100320676 | System and Method for Monitoring Image Forming Machine Media Stack Height and Method of Calibrating Stack Height Sensing in the Monitoring System - A system and method for monitoring media stack height utilizes a pick mechanism and stack height sensing mechanism. The pick mechanism has a pick arm and a pick roller, the arm rotatably mounted at one end to pivot about an axis and change its angular position relative thereto. The roller rotatably mounted to an opposite end of the arm contacts a media stack top and is rotatably driven to feed sheets one at a time from the stack top changing the stack height. The angular position of the arm relative to the stack changes as the stack height changes. The stack height sensing mechanism arranged on and adjacent to the arm senses arm angular displacement as the stack height changes to provide an indication of the sheet quantity remaining in the stack. A method for calibrating stack height sensing of the monitoring system provides one or more calibration points such as at “full stack” and “stack out” conditions. | 12-23-2010 |
20110056266 | Method For Calibrating Stack Height Sensing In A Media Stack Height Monitoring System In An Image Forming Machine - A method of calibrating stack height sensing in a media stack height monitoring system in an image forming machine includes sensing the angular position of a pick mechanism arm, generating electrical signals having levels correlated to the pick mechanism arm angular positions that correspond to different stack height levels, measuring and storing at least one value corresponding to the level of the electrical signal at least at one of two calibration points: “full load” and “stack out” conditions of the media stack, estimating either the amount or percent of media sheets remaining in the media stack corresponding to measured and stored value of the electrical signal level at the at least one calibration point, and indicating either of the amount or percent of media sheets remaining in the media stack. | 03-10-2011 |
