A medium transport device includes a feeding roller that feeds a recording medium, a transport roller that transports the recording medium toward a recording head, and a transport motor which is a common driving source for the feeding roller and the transport roller. The medium transport device includes a power transmission mechanism that transmits power of the transport motor to the feeding roller, and a control section that controls a current of the transport motor. The control section measures a current value flowing through the transport motor during driving as a measured current value, and adds a predetermined offset value to the measured current value to set a second limit value as a limit value of the current supplied to the transport motor.

Provided are: a holding unit configured to rotatably hold a roll body on which a medium is wound; a transport unit configured to transport the medium unwound from the roll body; a tension applying unit configured to press the medium between the holding unit and the transport unit to apply tension to the medium; a driving portion configured to provide driving force to the tension applying unit; a control unit configured to control the transport unit and the driving portion; and a detector configured to detect a load applied to the transport unit, and the control unit controls the driving force by the driving portion on the basis of the load detected by the detector to adjust the tension applied to the medium.

A sheet conveyor is provided for transporting a sheet. The sheet conveyor includes a supplying conveyor, a receiving conveyor and a sheet guidance unit. The receiving conveyor includes a support surface arranged for supporting the sheet on a contact side of the sheet and an attraction unit arranged for attracting the sheet to the support surface. The supplying conveyor includes a transport belt being arranged for advancing the sheet in a transport direction along a transport path towards the support surface of the receiving conveyor; the sheet having two side edge portions relative to the transport path. The sheet guidance unit is arranged at a downstream end of the transport path for guiding the sheet towards the receiving conveyor, wherein said sheet guidance unit includes a lifting element arranged for lifting both side edge portions of the sheet away from the support surface while a middle portion of the sheet in between both side edge portions is guided towards the support surface.

In one example in accordance with the present disclosure a media transport device is described. The device includes a number of drive rollers coupled to a frame. A number of media rollers are also coupled to the frame. The media rollers are in contact with, and rotated by, the number of drive rollers. Media rollers in a first set have a first diameter and media rollers in a second set have a second diameter that is different from the first diameter. The device also includes a number of pinch rollers coupled to the frame. The pinch rollers are in contact with the number of media rollers to form a number of nips through which media passes along a feed path.

A sheet material processing unit (20, 22, 24) comprises a transport system (32) for transporting sheets (12) or parts thereof from a respective input end (20i, 22i, 24i) to a respective output end (20o, 22o, 24o). A gripper unit (46) is releasably coupled to the transport system (32) and is configured for holding at least a part of one of the sheets (12). Additionally, at least one handover mechanism (47d, 47r) is provided being configured for decoupling the gripper unit (46) from the transport system (32) and providing the gripper unit (46) to a neighboring sheet material processing unit (20, 22, 24) and/or receiving a gripper unit (46) from a neighboring sheet material processing unit (20, 22, 24) and coupling the received gripper unit (46) to the corresponding transport system (32). Additionally, a sheet material processing machine (10) is presented which comprises at least two such sheet material processing units (20, 22, 24).

An example method comprises operating a drive unit to advance a substrate in a substrate advance direction toward a printing station. At the printing station, a first line is printed onto the substrate. A drive unit is instructed to advance the substrate in the substrate advance direction by a target amount, and a second line is printed onto the substrate. The distance between the first and second lines in a direction perpendicular to the substrate advance direction is calculated and, based on the calculated difference, a tension of the substrate is modified.

A processing system includes a stacker on which at least one medium recorded with an image is stacked, a holding unit configured to hold the medium, a processing path extending from the stacker to the holding unit, a pick roller configured to transport the medium from the stacker to the processing path, a reading unit configured to read the medium transported through the processing path, and a control unit configured to store indication data indicating an index of whether to transport a medium to the holding unit, wherein, when receiving a processing instruction from a user, the control unit is configured to cause the pick roller to transport a medium from the stacker to the processing path, and determine whether to transport the medium to the holding unit, based on read data and the indication data, the read data being acquired by reading the medium by the reading unit.

A medium-discharging device includes: a medium-discharging section that discharges a medium; a medium-receiving tray that receives the medium discharged by the medium-discharging section; a light-emitting section that emits light to the medium-receiving tray; and a control section that controls the light-emitting section, in which the medium-receiving tray is configured to switch between a first state in which the medium-receiving tray is stored in an apparatus main body that includes the medium-discharging section and a second state in which the medium-receiving tray protrudes from the apparatus main body, and the control section controls the light-emitting section in accordance with a state or operation of the medium-receiving tray.

An image forming apparatus includes a housing, a sheet conveyor, a sheet stacker, and circuitry. The sheet conveyor is configured to convey a sheet on which liquid is applied. The sheet stacker is configured to stack the sheet conveyed by the sheet conveyor. The circuitry is configured to control conveyance of the sheet. The circuitry is configured to cause the sheet conveyor to expose the sheet on which the liquid is applied, to an outside of the housing, and convey the sheet to the sheet stacker.
