An image forming apparatus includes an accommodating part configured to accommodate a sheet-like medium wound in a roll shape, an apparatus main body provided with a conveyer and an image forming engine, an electrically driven cutter, a cover configured to take a closed position for forming an exposable portion of a conveying path downstream in the conveying direction of the cutter and an open position to expose the exposable portion of the conveying path to the outside, a detector configured to detect a conveyance jam of the medium at a position downstream in the conveying direction of the exposable portion of the conveying path, a notifier configured to make notification to a user, and a controller configured to cause the notifier to prompt the user to cut off the medium at an arbitrary position in the exposable portion of the conveying path when the detector detects the conveyance jam.

A printing apparatus includes a control unit that, when continuously printing on a plurality of cut sheets of a same size, controls a print unit to cause a transfer member to continue movement, controls the print unit and a supply unit so as to stop supply of a cut sheet by the supply unit based on information concerning a time taken to process image data representing an image of a print target by an image processing unit, and controls the print unit not to form an ink image in a partial area on the transfer member that passes through a transfer area at a timing when the supply of the cut sheet to the transfer area is stopped, and to form the ink image in a remaining area.

A printing system includes a print station disposed at a sheet transport path, a feed section arranged to feed media sheets of different media types into the transport path so as to be fed sequentially to the print station, and a controller arranged to receive print instructions concerning images to be printed, to schedule a sequence of the media sheets, and to control the feed section and the print station such that each image is printed on a sheet of a media type that has been specified for that image in the print instructions. A sensor is arranged at the transport path for detecting a quality condition of the sheets being fed to the print station, and the controller is adapted to receive a quality signal from the sensor and, when the quality of a sheet is found to be insufficient, to skip that sheet and to reroute the corresponding image to another scheduled sheet that is compatible with the print instructions.

A printing apparatus comprises a conveyance control unit which controls conveyance of printing sheets so that a trailing edge of a preceding sheet as a printing sheet precedingly fed from the stacking unit and a leading edge of a succeeding sheet as a printing sheet succeedingly fed from the stacking unit overlap each other; and a skew correction unit which performs skew correction of the succeeding sheet while the succeeding sheet overlaps the preceding sheet by the conveyance control unit. The skew correction unit makes the leading edge of the succeeding sheet abut against the conveyance roller during a time from an end of a last line feed operation by the conveyance roller for printing on the preceding sheet by the printing unit to start of a next conveyance operation.

A method of duplex printing on a cut sheet printer having a sheet supply system for feeding sheets to a print station in a first orientation for printing a first image on the first side of the sheet and then in a second orientation for printing a second image on a second side of the sheet includes, for each sheet: (a) estimating a likelihood P1 that, in a print process for printing the first image, the sheet will become damaged to such an extent that the damage will compromise a later print process for printing the second image; (b) comparing the likelihood P1 to a threshold T; and (c) if the likelihood P1 exceeds the threshold T, reversing the print order so that the second image is printed before the first image. The method ensures that the riskier image is printed on the duplex pass. The chances of the sheet with the simplex image then successfully passing through the duplex pass are then increased.

A printing apparatus includes a first feeding roller, a feeding motor configured to drive the first feeding roller, a second feeding roller, a conveyance roller, a conveyance motor configured to drive the conveyance roller, a printing unit configured to print the printing sheet, a detection sensor configured to detect the leading edge of the printing sheet, and a control unit configured to, when the printing unit performs a printing operation on a preceding sheet, drive the feeding motor in synchronization with the conveyance motor before the detection sensor detects the leading edge of a succeeding sheet, and continuously drive the feeding motor so that the conveying speed of the succeeding sheet by the feeding motor becomes higher than that of the preceding sheet after the detection sensor detects the leading edge of the succeeding sheet.

Examples of stalling of operation of imaging devices are described herein. In an example, the imaging device includes an input roller assembly to transport a medium in the imaging device and a line feed roller assembly disengagably coupled to the input roller assembly to selectively drive the input roller assembly. To stall the operation of the imaging device, a line feed shaft of the line feed roller assembly can be automatically disengaged from the input roller assembly to discontinue advance of the medium along a print path.

A media feeder including a tray arranged to hold media, a motor arranged to move the tray in a first direction and a second direction opposite the first direction, a sensor arranged to detect at least one position of the tray, a processor arranged to execute a set of steps, and a memory element arranged to store the set of steps. The set of steps includes: receiving a first input from a user selecting a first loading preference; moving the tray with the motor in the first direction a first distance from the first position to a second position; loading a first quantity of media into the tray; and, moving the tray in the second direction until a first sheet of the first quantity of media is in a feeding position.

A recording apparatus includes a medium mounting section on which a medium is to be mounted, a reverse-feeding path for reversing the medium that has been fed from the medium mounting section, a recording unit configured to perform recording onto the medium that has been reversed by the reverse-feeding path, and a reverse-discharging path for reversing the medium on which recording has been performed by the recording unit and for discharge the medium to a discharge section configured to discharge the medium, in which when viewed in a medium width direction intersecting a medium transport direction, a path section for reversing the medium in the reverse-feeding path and a path section for reversing the medium in the reverse-discharging path have portions overlapping each other in the vertical direction.

A registration system for a printing device and a method for controlling the same are disclosed. For example, the registration system includes at least one sensor to detect a position of a print media, a platform comprising a plurality of cellular omni wheels, and a processor communicatively coupled to the at least one sensor and the plurality of cellular omni wheels, wherein the processor calculates a desired movement of each one of the plurality of cellular omni wheels based on the position of the print media.
