Inkjet apparatus and collection apparatus

In a printing system capable of selectively performing duplex printing and simplex printing, a first input unit and a second input unit are adjacent to each other. A first output unit and a second output unit are adjacent to each other. In duplex printing, a sheet supplied from the first input unit is printed on a first side thereof in a first printing apparatus and the traveling direction thereof is changed at a changing unit while the sheet is reversed, and then the sheet is printed on a second side thereof in a second printing apparatus and output to the second output unit. In simplex printing, a sheet supplied from the first or second input unit is printed on one side thereof and the traveling direction thereof is changed at the changing unit, and then the sheet is output to the first or second output unit.

Printing system, sheet processing system, and sheet direction changing apparatus

In a printing system capable of selectively performing duplex printing and simplex printing, a switching unit switches a sheet travel path between a first path and a second path parallel to each other, and reverses the sides of a sheet that passes along the first path. In the duplex printing, a sheet is printed on a first side by a first printing apparatus, reversed by the switching unit, and printed on a second side reverse of the first side by a second printing apparatus. In the simplex printing, only one side of a sheet is printed by the first printing apparatus and/or second printing apparatus. First and second input units introduce sheets into the first and second paths, respectively; and first and second output units receive printed sheets that have traveled along the first and/or second paths.

Printing system, sheet processing system, and sheet-path switching apparatus

A printing apparatus includes a conveyance unit, a printing unit, a detection unit, and a control unit. The conveyance unit conveys a sheet that is a continuous sheet. The printing unit prints an image onto the conveyed sheet. The detection unit detects a splice of the conveyed sheet. A following sheet area follows and is continuous from the splice. The control unit adjusts, in response to the detection unit detecting a splice of the conveyed sheet, the conveyance by the conveyance unit of the following sheet area depending on conveyance characteristics of the following sheet area.

Printing apparatus and printing method

A printing apparatus using a print head of an inkjet-type, in which, if a splice is detected during printing, an area of a following part of a continuous sheet that follows the splice is used to perform image-quality adjustment such as color shading adjustment, an adjustment of a gap between the print head and a sheet, and a color registration adjustment of the print head.

Apparatus and method of printing images on a continuous sheet

This invention relates to a printing apparatus and a conveyance control method capable of allowing even an arrangement having a plurality of conveyance rollers in a printing medium conveyance path to accurately control conveyance of a printing medium. A pattern having a predetermined uniform density is printed on a printing medium a plurality of number of times by using a printhead while conveying the printing medium and changing the conveyance amount by a small amount. A conveyance correction amount obtained on the basis of the conveyance amount upon printing a pattern selected from a plurality of printed pattern is stored in a storage medium. Conveyance of the printing medium is controlled while correcting the conveyance amount of the printing medium by the conveyance means on the basis of the conveyance correction amount stored in the storage means.

Printing apparatus and conveyance control method

An ink jet recording device is provided comprising a head recovering unit for operating for recovering a discharge function of an ink jet recording head, a cap member disposed on the head recovering unit to tightly close ink discharge ports, a recording medium conveying mechanism for conveying a recording medium, and a connecting unit for switching transmission and non-transmission of a driving force to the head recovering unit in conjunction with a capping operation of the cap member, and makes it possible to provide a drive switching mechanism which is convenient and highly reliable, reduce a number of driving source and realize a recording apparatus having a high reliability at a low cost while saving a space.
