A printing system for printing on sheets of media having a non-uniform thickness profile. A user interface is controlled to instruct the operator to load a media tray with a stack of media having a specified pattern of media orientations. A media transport system picks sequential sheets of media from the media tray. A front end supplies sequential image data having orientations in accordance with the specified pattern of media orientations. A printing module sequentially prints the supplied image data on the sheets of media in accordance with the specified pattern of media orientations.

A printer includes a record section, a discharge section, a mount section, a movable rib, a move section, and a control section. The record section records on a sheet by ejecting an ink to the sheet. The discharge section discharges the sheet. The mount section has a mount surface on which the sheet discharged is mounted. A movable rib is configured to protrude from the mount surface and supports the sheet. The dimension of the movable rib in an A-direction is larger than the dimension thereof in a Y-direction. The move section moves the movable rib in a C-direction. The control section controls, based on temperature and humidity information, movement of the movable rib made by the move section.

The inkjet image forming device comprises a post-processing device to post-process the paper ejected from the print engine, wherein the post-processing device comprises a loading part in which the paper conveyed from the print engine is to be loaded, and an air blower including an air blowing part to blow air toward the loading part, and a shutter to be rotatable between a closed position and an open position in the air blowing part to adjust an amount of air to be blown from the air blowing part.

An apparatus and method of conveying parts underneath an array of inkjet printheads in such a way as to minimize print defects caused by variation in motion. The conveyor is composed of a series of rigid conveyor track segments that are forced to move in a precise straight line due to a combination of accurate ball bearing wheel assemblies and precision machine guideways that are incorporated into the conveying system.

A sheet stacker includes a sheet stacking portion, a guide portion, and an air blower. The sheet stacking portion is configured to stack a sheet bundle. The guide portion is configured to receive a leading end of a sheet conveyed toward the sheet stacking portion and guide the sheet downstream in a sheet conveyance direction in which the sheet is conveyed. The air blower is disposed above the sheet stacking portion and configured to blow air toward the sheet on a downstream side, in the sheet conveyance direction, from a position at which the guide portion receives the leading end of the sheet.

In a printing medium accommodating apparatus, a printing medium discharged from a discharge port of a printing apparatus is stacked. The printing medium accommodating apparatus includes: a receiving member configured to receive a printing medium discharged from the discharge port; and a holding member having a holding portion configured to hold one end of the receiving member, the holding member being capable of being connected with a first attachment unit attached to the printing apparatus, the holding member being configured to be capable of transitioning from a first state where the holding member is connected with the first attachment unit to a second state where the holding member is separated from the first attachment unit.

A printing medium accommodating apparatus is a printing medium accommodating apparatus in which to stack a printing medium discharged from a discharge port of a printing apparatus. This apparatus includes: a receiving member configured to receive a printing medium discharged from the discharge port; a holding member configured to hold one end of the receiving member; and a turning member configured to turn the holding member, and includes a first attachment unit capable of attaching the turning member to an insertion slot provided in the printing apparatus.

A medium placement device includes a placement unit configured to have cut single paper thereon, a cover member configured to have single paper supplied to or discharged from an opening portion thereon, and a movement unit configured to move the cover member between a first position and a second position that is lower than the first position.

A medium receiving tray has a first tray and a second tray. A movable support having a second support surface for supporting media is disposed in the second tray. When the medium receiving tray is in a first state, the movable support is positioned above a first support surface of the first tray. When the medium receiving tray is switched from the first state to a second state, a free end is detached from the downstream end of the first support surface and displaced downward, and the second support surface is thereby inclined upward toward the downstream in a medium discharging direction.

A printer having front-end paper feeding and front-end paper outputting and being capable of changing a paper discharge path, said printer comprising a housing (10) and a paper discharge unit (40), the paper discharge unit (40) comprising a first paper discharge mechanism (401) and a paper discharge channel (50) which consists of upper and lower casings (1011, 1012), a front end surface of the housing (10) being a vertical flat surface A, a paper feed port (30) and a paper output port (20) being horizontally arranged on the flat surface A, the paper feed port (30) being located beneath the paper output port (20), the paper discharge channel (50) at the front of the first paper discharge mechanism (401) being provided with a paper conveyance system capable of changing a paper discharge path.
