摘要： A printing device that performs printing on a medium includes an inkjet head, a main scan driving unit, a sub scan driving unit, and a control unit, where the control unit sets a sub-scanning movement amount based on a basic movement amount, which is a basic movement amount set according to print conditions, and a value indicating a distance for increasing or decreasing the sub-scanning movement amount in the print conditions set at the time of inputting an input correction value. Furthermore, a storage is further provided, which stores a first correction coefficient used when the basic movement amount is within a first range, and a second correction coefficient used when the basic movement amount is within a second range smaller than the first range, and the control unit sets the sub-scanning movement amount based on the basic movement amount and the calculated correction value.

摘要： Methods, Apparatus, Devices and Systems herein load a firing distance into a distance counter of a printing device. The firing distance is the distance from the current position of a printhead of the printing device to a marking location on a substrate and the distance is calculated based on an angular encoder operatively associated with a roller used to transport a marking media to the printhead for marking. These devices and methods count the firing distance in angular distance increments as a function of the encoder angular position to correct for encoder roller runout using the distance counter, based on relative movement of the substrate and printhead. When the distance counter reaches the last discrete distance increment corrected for encoder roller runout of the firing distance, these devices and methods load the fractional remaining distance of the firing distance into a time counter of the printing device. Then, the fractional remaining distance is counted using velocity-based distance increments at regular time intervals using the time counter. When the time counter reaches the last velocity-based calculated distance increment of the fractional remaining distance, the marking material is transferred from the printhead to the substrate.

摘要： Provided is a printing apparatus that includes a printing unit, a conveyance belt that is stretched over a first roller and a second roller such that a tension is applied to the conveyance belt, and a control unit configured to perform on the conveyance belt a forward rotation operation configured to convey a medium in a conveyance direction and a reverse rotation operation configured to convey the medium in a reverse conveyance direction. When the reverse rotation operation has been performed during a print pause period and the tension at the end of the print pause period has changed from the tension when printing of a first image is complete due to the reverse rotation operation performed during the print pause period, the control unit corrects a rotation amount of the conveyance belt in a first rotation direction during printing of a second image.

摘要： A sheet aligning device includes a support member, a regulation member, a regulation member moving mechanism, and an alignment member. The support member supports leading ends of sheets. The regulation member is connected to the support member and is provided to face an inclined tray in such a way as to define a sheet entry space in which the leading ends of the sheets enter. The regulation member moving mechanism is configured to, each time a sheet is conveyed onto the inclined tray, move the regulation member in a separating direction to widen the sheet entry space, and then in an approaching direction to narrow the sheet entry space. The alignment member aligns the sheets by abutting on rear ends of the sheets.
