A printing apparatus includes a conveyance unit, a printing unit, a platen section facing the printing unit, a regulation unit arranged on a downstream side of the printing unit in the conveyance direction and configured to regulate a height position of the print medium, and a guide section arranged on a downstream side of the platen section. The guide section includes a first declined section, a second declined section arranged on the downstream side of the first declined section in the conveyance direction, and an inclined section inclined from the second declined section to the downstream side in the conveyance direction. A declination of the second declined section is more moderate than that of the first declined section, and the regulation unit faces the guide section.

A recording apparatus includes a recording portion that records an image on a sheet, a first conveyance path in which a cut sheet serving as the sheet is conveyed toward the recording portion, a second conveyance path in which a continuous sheet serving as the sheet is conveyed toward the recording portion, a common conveyance path in which the sheet is conveyed in a conveying direction from a junction point at which the first conveyance path and the second conveyance path join together to the recording portion, and a control portion that controls the conveyance of the sheet. When the sheet is not detected in the second conveyance path after a sheet conveyance abnormality is detected, while the sheet is detected in the common conveyance path, the control portion performs a discharge operation of conveying the cut sheet from the first conveyance path toward the recording portion.

Recording apparatus

A sheet stacking apparatus is provided. A conveyor unit performs stacking of sheets discharged from a printing apparatus and conveying of stacked sheets. A detection unit detects whether or not the printing apparatus is currently discharging a sheet. A control unit, so as to secure a stacking space for a sheet discharged from the printing apparatus on the conveyor unit, controls a feeding operation of the conveyor unit correspondingly to a period of time over which the detection unit detected that the printing apparatus is discharging a sheet.

A printing apparatus according to an embodiment of this invention brings, out of a cleaning unit that cleans a transfer member in contact with a transfer member and an application unit that applies a reactive liquid with ink to the transfer member, the cleaning unit into contact with the transfer member to clean the transfer member by the cleaning unit at the start of the printing operation. Alternatively, out of the application unit and an absorbing unit that absorbs a liquid component from the reactive liquid applied by the application unit in contact with the transfer member, the printing apparatus brings the application unit into contact with the transfer member to apply the reactive liquid by the application unit.

Inkjet printing apparatus

According to an embodiment of this invention, a printing apparatus capable of cleaning a transfer member continuously while downsizing the apparatus and a cleaning method of the same are provided. The printing apparatus includes a cleaning roller configured to apply a cleaning liquid to the transfer member while rotating in contact with the transfer member, a liquid tank configured to reserve the cleaning liquid so that a part of the cleaning roller is immersed in the cleaning liquid, and a removal unit configured to remove a blot by contacting the surface of the cleaning roller which rotates in the liquid tank.

An inkjet printing apparatus includes a printhead configured to form an image by discharging ink to a transfer member, a transfer unit configured to transfer the image from the transfer member to a print medium, and an application unit configured to apply a first liquid to the transfer member prior to formation of the image by the printhead. The inkjet printing apparatus also includes a first drying unit configured to dry the first liquid applied to the transfer member by the application unit by blowing air using a first air blower before the ink is discharged by the printhead to the transfer member.

Inkjet printing apparatus and related printing method in which a liquid applied to a transfer member is dried before ink is discharged by a printhead

A printing apparatus includes a transfer member that rotates, a printhead that forms an image on the transfer member, and a transfer unit that transfers the image to a print medium. An application unit, provided at a downstream side of an area, at which the transfer unit transfers the image to the print medium, in a rotation direction of the transfer member, applies a cleaning liquid to a region on the transfer member after the image is transferred to the print medium. In addition, a collecting unit, provided between the printhead and the application unit, in the rotation direction of the transfer member, includes a collection roller that rotates in contact with the transfer member, in a direction opposite to the rotation direction of the transfer member, for collecting the cleaning liquid applied to the transfer member by the application unit.

In a printing apparatus, an indefinite area in which slits are not formed is configured in a portion of a linear encoder scale in a rotation direction, and an adjustment unit adjusts the timing of discharge from a printhead with respect to a first printing area out of a plurality of printing areas on a rotating member, without using a detection result of a first encoder sensor, based on a detection result of a second encoder sensor, the first encoder sensor being provided at a position corresponding to the indefinite area during a discharge of printing material with respect to the first printing, and the second encoder sensor being provided at a position that does not correspond to the indefinite area during the discharge of the printing material with respect to the first printing area.

Printing apparatus and printing method

When fixing is not necessary in a printing apparatus including a fixing unit, a sheet to be conveyed is allowed to avoid the fixing unit. Specifically, a fixing unit-bypass path is provided on a conveying path corresponding to the fixing unit. Further, when a surface treatment material is not applied to a sheet from a surface treatment material applying head, that is, when fixing processing is not performed by the fixing unit, a sheet is conveyed along a fixing unit-bypass path. Since a sheet is conveyed along an bypass path when fixing processing is not performed as described above, it is possible to prevent a sheet from being affected by heat or the like while the sheet passes through the fixing unit.

A decision is made for each page as to whether to allow image printing on that page, by comparing the remaining sheet length DL with a length of an image about to be printed, IL. A length of a non-printed, rear-end cut sheet is also checked to determine whether the non-printed cut sheet needs to be further cut into smaller sheets. This arrangement can prevent a complete image to be printed in one page from being broken and only partly printed in the last portion of a paper roll, ensure that printed cut sheets and non-printed cut sheets are stably conveyed and discharged and enable the non-printed cut sheets to be almost equal in size so that they can be properly accommodated in the associated tray.

There are provided a printing apparatus, a method for controlling the printing apparatus, and a storage medium. The printing apparatus includes a conveying unit that conveys a print medium; a print head that applies a color material on the print medium; an obtaining unit configured to obtain, in the case where a first surface of the print medium on which a first image is printed comes in contact with the conveying unit, information on a printing condition of the first surface that becomes a factor of changing a conveying speed of the print medium in the predetermined direction; and a control unit configured to control timing of applying a color material on a second surface of the print medium that is a surface at the opposite to the first surface according to the printing condition indicated by the information obtained by the obtaining unit.
