Abstract: There is provide an image processing apparatus including a carriage with a recording head and a sensor mounted thereon, a conveyer, and a controller. The controller carries out: acquiring a recording data, a front edge margin, and a tail edge margin, determining whether or not at least one of first and second reference values is less than a threshold value, and a positioning process. When at least one of the first and second reference values is less than the threshold value, then the controller carries out: a front edge detecting process, a first recording preparation process, and a recording process. When at least one of the first and second reference values is not less than the threshold value, then the controller carries out: a second recording preparation process, and the recording process.

Abstract: An image forming system, having a recording head, a sheet conveyer, an inverting mechanism, and a controller, is provided. The sheet conveyer conveys a sheet in a sheet-conveying direction. The sheet is nipped at nipping points located at positions upstream and downstream in the sheet-conveying direction with respect to a discharging position. The inverting mechanism inverts the sheet from a first side to the second side. The controller determines an initial arrangement of the sheet in the sheet conveyer where image-forming on the second side starts, and controls a length of a period between time, when image-forming on the first side of the sheet in the posture with the first side facing the recording sheet is completed, and time, when the image-forming on the second side of the sheet inverted and refed to the sheet conveyer starts, based on the determined initial arrangement of the sheet in the sheet conveyer.

Abstract: An image forming device comprises a media container accommodating a sheet-type medium, an image forming engine, a media conveyor configured to convey the sheet-type medium along a conveyance path from the media container to the image forming engine. The media conveyor has a plurality of conveying rollers including a first conveying roller arranged on an upstream side of the image forming engine and a second conveying roller arranged on a downstream side of the image forming engine. The image forming device further comprises a cutter arranged on an upstream side along the conveyance path with respect to the second conveying roller, and a controller. The controller is configured to control the media conveyor in such a manner that the cut sheet-type medium is conveyed and discharged toward outside after a power is on and before first execution of the image forming process.

Abstract: A first conveyance path and a second conveyance path are formed in a housing. The first conveyance path extends in a conveyance direction to reach a first discharge port for discharging a sheet. The second conveyance path extends in the conveyance direction at a position higher than the first conveyance path to reach a second discharge port for discharging a sheet. The second discharge port is located at a position upstream of the first discharge port in the conveyance direction. A first print engine is provided at the first conveyance path. The first print engine is configured to print an image by using a recording agent on a sheet conveyed along the first conveyance path. A second print engine is provided at the second conveyance path. The second print engine is configured to print an image by using a recording agent on a sheet conveyed along the second conveyance path.

Abstract: A controller acquires image recording data for recording a plurality of passes; determines a first movement distance of a carriage for recording each of the plurality of passes; determines a non-usage ratio that is a ratio of a number of unused nozzles in a last pass of the plurality of passes to a total number of the plurality of nozzles arranged in a conveyance direction; determines a second movement distance in a particular pass which is recorded before the last pass, the second movement distance being a movement distance of the carriage assuming that the particular pass is recorded without using nozzles of a first ratio smaller than or equal to the non-usage ratio; and in response to determining that the second movement distance is shorter than the first movement distance, performs image recording of the particular pass without using the nozzles of the first ratio.
