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.

The present subject matter discloses detection of positions of print medium for driving the print medium for printing in a printing system, in an example implementation, a motor is operated for driving the print medium, at a first specific speed, along a media-path in the printing system. After a first specific number of rotations of the motor, it is detected, based on identification of a torque change event, that the print medium at a de-skew position in the media-path. At the de-skew position a leading edge of the print medium is at a de-skew unit of the printing system and the torque change event is indicative of a deviation in a current operating torque of the motor from a standard operating torque of the motor.

A printing apparatus includes a print section configured to perform printing on a medium, a supply path configured to supply the medium toward the print section, a feeding roller configured to feed the medium along the supply path from an upstream side to a downstream side in a transport direction, a toothed roller provided on the downstream side of the feeding roller in the transport direction, a drive source configured to rotate the feeding roller and the toothed roller, and a controller configured to control driving of the drive source. The controller performs rotation control for rotating the feed roller prior to the rotation of the toothed roller with which the medium has collided. The controller performs the rotation control when the controller determines that the grammage of the medium is greater than or equal to a threshold value.

A media sheet drive has a continuous belt of a dielectric material for transporting sheet media supported on the belt in a transport direction. A launch mechanism is used to launch a sheet medium onto a top surface of the belt. A charging circuit including a charging roller is used to charge a top surface of the sheet medium and the belt as the sheet medium is launched. Charging acts to generate an electrostatic tacking force to tack the sheet medium to the belt. The charging roller has a second function to smooth out curled edges of paper as it is acted on by the charging circuit so that the full extent of a launched sheet medium may be subject to the electrostatic tacking force.

There is provided a recording apparatus that start conveying a subsequent sheet in a state where an overlap amount of a preceding sheet and the subsequent sheet is not determined, acquires the overlap amount after the sheet conveyance is started, acquires distance information about a distance between a trailing edge of an image of a last line on the preceding sheet and a leading edge of an image on the subsequent sheet based on recording data and the overlap amount, and generates recording data for image forming of recording data of the last line on the preceding sheet and recording data of a first line on the subsequent sheet in the same scan by a recording unit, based on the acquired distance information.

An image forming apparatus includes a housing unit that includes an intermediate plate, a lift-up unit, a first detection unit, a second detection unit, a feeding unit, a control unit, a first acquisition unit that acquires a first driving amount, a storage unit that stores a threshold, a determination unit that determines that a recording material is overloaded on the intermediate plate when the first driving amount is smaller than the threshold, a second acquisition unit that acquires a second driving amount, a correction unit that obtains a differential amount by subtracting a predetermined driving amount from the second driving amount acquired by the second acquisition unit, and corrects, on a basis of the differential amount, the threshold stored in the storage unit or the first driving amount acquired by the first acquisition unit.

A paper conveyance device includes a paper feed unit, a conveyance rotator, a conveyance guide, a multi-feed detection unit, and a control unit. The control unit causes an ultrasonic sensor to transmit an ultrasonic wave in a detection section. The control unit sets a detection execution section and a detection skip section in the detection section. The control unit does not determine whether multi-feed has occurred in the detection skip section. The control unit sets the detection skip section based on a time point at which vibration is applied to conveyed paper.

A printing apparatus includes a feeding roller configured to feed a printing sheet stacked on a stacking unit, a conveyance roller configured to convey the printing sheet fed by the feeding roller, a printing unit configured to print the printing sheet conveyed by the conveyance roller, a conveyance control unit configured to control conveyance of printing sheets so that the trailing edge of a preceding sheet as a printing sheet precedingly fed from the stacking unit and the leading edge of a succeeding sheet as a printing sheet succeedingly fed from the stacking unit overlap each other, and a determination unit configured to determine whether to convey the succeeding sheet to a position facing the printing unit while keeping an overlap state between the preceding sheet and the succeeding sheet.

There is provided a printing apparatus including: a housing including a wall with an opening; a mounting section configured to allow a cartridge to be mounted through the opening; a head with a nozzle to eject a liquid; a processing unit including a processing section configured to process a print medium; and a head carriage holding the mounting section and the head. The processing unit is located upstream of the head carriage in a conveyance direction of the print medium, the conveyance direction being a direction in which the print medium passes through a support facing the head.

A recording apparatus includes a recording head that performs recording; a feeding roller that feeds out a medium that has been set, a transport roller that transports the medium fed out by the feeding roller toward a facing position facing the recording head; an auxiliary roller that is provided between the feeding roller and the transport roller and that assists in the transport of the medium; a motor that generates a driving force; and a drive train that is configured to transmit the driving force of the motor to the auxiliary roller and the transport roller.
