A web handling system is disclosed. The web handling system includes first dancer rollers coupled to engage and move a web of a print medium in a forward and backward direction upon stopping a printing operation and allow forward motion during the printing operation.

An inkjet printing system may include an inkjet printing device, a print media finishing device, and a conditioner selectively coupled within a housing of the print media finishing device and in alignment with a print media exit of the inkjet printing device where the conditioner includes a number of heated pressure rollers to condition the print media prior to introduction into the print media finishing device.

Examples described herein include a print media edge repair system that includes a first repair element disposed adjacent to a media handling path to repair a leading edge of a sheet of print media as the sheet of print media moves into a position relative to a printing system associated with the print media edge repair system. The print media repair system may also include a second repair element disposed opposite the first repair element across the media handling path to repair a trailing edge of the sheet of print media as the sheet of print media moves into the position relative to a printing system.

A web handling system is disclosed. The web handling system includes first dancer rollers coupled to engage and move a web of a print medium in a forward and backward direction upon stopping a printing operation and allow forward motion during the printing operation.

A printer includes an inversion path that inverts a medium, an inversion roller having a circumferential surface that serves as a path surface of the inversion path, an advancing roller having a circumferential surface that faces both a first path that is a path before the medium is inverted and a second path that is a path after the medium is inverted. The printer also includes an idler roller disposed above the inversion roller and a supply mechanism that is disposed above the idler roller and that supplies the medium toward the recording head. The inversion roller is made smaller in diameter than the advancing roller, and the inversion roller is positioned within a height range of the advancing roller, and at least part of the idler roller is positioned within the height range of the advancing roller.

An image forming apparatus includes a plate, a feeding unit that feeds a recording material placed on the plate, an image forming unit that form an image on the fed recording material, a conveying unit to convey a recording material pinched by a nip pressure from a rotating member nip portion, a switching unit to switch the nip pressure, a detecting unit, and a control unit. The detecting unit detects property information regarding the fed recording material. In response to an instruction to form the image on the recording material and before detection of property information completes, the control unit controls to switch the nip pressure based on information regarding image forming on the recording material, and after detection of the property information completes, the control unit controls to switch the nip pressure based on the information regarding the image forming on the recording material and the detected property information.

Provided is a technique that enables proper sorting of discharged print media by suppressing curling of each of the print media sufficiently. A determining unit determines a curling suppressing operation to be executed such that in a case where sorting operation is executed, the suppressing operation having a higher effect of suppressing curling is executed than in a case where the sorting operation is executed. Then, a print control unit controls a print head to perform printing on print media while executing the suppressing operation determined by the determining unit.

Provided is a printing apparatus comprising: a discharging unit configured to convey and discharge print media; a tray configured to receive print media discharged in a first direction from the discharging unit; and a drive unit configured to move the tray in a second direction perpendicular to the first direction. In discharging print media, the tray is moved in the second direction to thereby receive the discharged print media at a plurality of different positions on the tray. The tray is movable to a take-out position being a position closer in the second direction to a take-out side where print media are taken out than any of the positions at which the tray receives the print media discharged from the discharging unit.

A flattening device includes: a holder configured to support the following components; at least one flattening roller set, including a first flattening roller and a second flattening roller arranged oppositely at two sides of a sheet medium conveying path; and a power mechanism configured to drive the first and second flattening rollers to rotate. A surface of the first flattening roller is distributed with n arc-shaped grooves arranged in parallel with an axis direction of the first flattening roller, wherein n is a natural number greater than or equal to 1; and a surface of the second flattening roller is provided with at least one arc-shaped protruding portion in rolling engagement with the arc-shaped grooves of the first flattening roller; and wherein, the first flattening roller and the second flattening roller are in rolling engagement to form a conveying passage for the sheet medium.
