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.

Printing apparatus, control method therefor and storage medium

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.

Printing apparatus, method and storage medium for conveying sheets intermittently to printhead while conveyed sheets partially overlap

Printing apparatus, method and storage medium for conveying sheets intermittently to printhead while forming overlaps state

The present invention provides a printing apparatus. The printing apparatus includes a feeding unit, a pair of rollers configured to nip a printing medium and to convey the printing medium fed by the feeding unit, a printing unit and a control unit. The control unit can execute successive overlapped conveyance in which the pair of rollers nip an overlapping portion between a trailing edge of a preceding printing medium and a leading edge of a succeeding printing medium and convey them. The control unit executes the successive overlapped conveyance at least on condition that printing of the preceding printing medium by the printing unit has ended.

Printing apparatus and control method

A printing apparatus comprises a feeding roller configured to feed a printing sheet, a conveyance roller configured to convey the printing sheet, a printing unit configured to print on the printing sheet, a conveyance control unit configured to control conveyance of printing sheets so that a trailing edge of a preceding sheet and a leading edge of a succeeding sheet overlap each other, an acquisition unit configured to acquire, before completion of a printing operation of the preceding sheet, information of a leading edge position of the succeeding sheet, 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 in accordance with the leading edge position of the succeeding sheet.

Printing apparatus, control method therefor, and storage medium

A control unit includes a moving unit that causes a recording unit to move in a reciprocating manner, a detection unit that detects a movement error of the moving unit, a control unit that controls the moving unit such that the recording unit is caused to move in a second direction if the movement error is detected while the recording unit is caused to move in a first direction, a notification unit that issues error notification according to a result of movement of the moving unit, and an execution unit that executes an operation for identifying a cause of the movement error of the moving unit in a case where the moving unit has been able to move in the second direction by the controlling of the control unit, wherein the notification unit issues error notification according to an execution result of the operation by the execution unit.

Control device, control method, and storage medium

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 a 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 determination unit which determines 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. The determination unit determines whether the printing sheet is suitable for overlap conveyance, and if the determination unit determines that the printing sheet is unsuitable for overlap conveyance, the conveyance control unit conveys the succeeding sheet while the succeeding sheet does not overlap the preceding sheet.

Printing apparatus and control method therefor

A printing apparatus includes a feeding unit configured to feed a printing sheet stacked on a stacking unit, a conveying unit configured to convey the printing sheet fed by the feeding unit, a printing unit configured to print the printing sheet conveyed by the conveying unit, and a control unit configured to control the feeding unit and the conveying unit. When continuously printing on the first surfaces of a plurality of printing sheets, the feeding unit forms an overlap state in which a trailing edge of a preceding sheet and a leading edge of a succeeding sheet overlap each other, and the conveying unit conveys the printing sheets while keeping the overlap state. When performing double-sided printing on the first surface and the second surface of the printing sheet, the feeding unit does not form the overlap state.

Printing apparatus, control method for printing apparatus, and storage medium

In a printing apparatus improvement of drying ability and reduction of consumed power are concurrently achieved by improving the efficiency of drying ink. More concretely, hot air is blown onto a print medium printed by ink, and a portion of the blown hot air is recovered and blown again. Before the hot air is blown, the print medium is heated by a preheating unit, making it higher than the dew point temperature of the blown hot air.

Printing apparatus and inkjet method

In an inkjet printing apparatus capable of automatic duplex printing, time required to fix ink is shortened and throughput is improved without producing uneven fixing. The inkjet printing apparatus includes a printing unit that prints onto a sheet, a fixing unit that heats a sheet printed by the printing unit, a conveying unit that conveys a sheet with respect to the printing unit and the fixing unit, and a controller that controls the conveying unit such that a printing region of a sheet printed on the first side by the printing unit passes through the fixing unit, and afterwards, the conveyance direction of the sheet is reversed in order to print on the second side and the printing region once again passes through the fixing unit. The controller variably controls the conveyance speed of the sheet when the printing region once again passes through the fixing unit.

Inkjet printing apparatus

An apparatus includes a printing unit which is disposed in a housing and configured to form an image on a sheet, an lid attached to the housing by a hinge mechanism, and a camera which is attached to the lid and configured to read an image on a document while the lid is open, wherein the sheet having the image formed by the printing unit is discharged on the lid, and when the lid is opened, the camera can read the document which is placed at a reading position below the camera.

Image forming apparatus

An image forming apparatus includes a printing section, a flatbed scanner section configured to read an original on a reading surface, and a moving mechanism configured to change the angle of the reading surface relative to an installation plane on which the apparatus is installed. The scanner section is capable of performing reading in each of a first mode where the angle of the reading surface is a first angle (vertical) and a second mode where the angle of the reading surface is a second angle (horizontal) different from the first angle.
