A hardcopy printing mechanism and a greeting card feeder retrofit kit therefor, along with a retrofitting method are provided for printing images on a first-sized media, and on both surfaces a second-sized greeting card media without removing the first-sized media from its normal supply tray. The hardcopy device may be an electrophotographic or inkjet printer preferably equipped with a duplexer module which inverts media from a printed first surface to an opposing second surface for printing an image thereon. For a printer having an alignment surface, and a width adjuster to push the first-sized media against the alignment surface, the greeting card feeder includes a biasing member which pushes the card stock against the alignment surface. The retrofit kit includes a supply of pre-scored greeting card stock and a software program with a group of greeting card images for a consumer to select from to print store-bought quality greeting cards.

A recording medium feed apparatus has a manual feed tray provided in open or closed state, a feed roller feeding a recording portion a recording medium on the manual feed tray, an arm body having a first end portion rotatably attached to a housing and a second end portion, a feed roller unit having a front end portion provided with the feed roller and a base end portion rotatably attached to the second end portion, and a driving source transferring driving force to the feed roller, wherein the arm body and the feed roller unit are vertically housed inside the housing when the manual feed tray is closed, and as the manual feed tray changes from closed to opened state, the arm body tilts toward outside, while a folding angle of the feed roller increases so that the feed roller abuts against a recording medium on the manual feed tray.

A paper feeder of a printer has a plurality of paper feeding paths to feed a printing paper, and a main fed roller feeding the printing paper to an image forming unit of an image forming apparatus. The paper feeding paths are disposed along an outer circumference of the main fed roller and confluent along a connecting conveyance path by the main feed roller. The connecting conveyance path is connected with a main conveyance path which guides the printing paper to the image forming unit of the image forming apparatus. By a single feed roller, the printing paper from the paper feeding cassette in an automatic paper feeding mode, the printing paper from a manual paper feeding tray in a manual paper feeding mode, and the printing paper being inverted and returned in double-sided printing, can be fed to the paper conveyance path efficiently. Because there is no need to prepare a separate feeding apparatus to convey the printing paper according to the respective printing modes, a structure of the printer can be simplified, and an internal space of the printer is reduced. As a result, a compact-sized printer requiring less manufacturing costs can be provided.

The invention provides a printing machine that uses an ink jet printmaking technology for printing a color or a plurality of colors on the cardboard of a case. The printing machine is provided with a feeder, a transmission mechanism used for moving the cardboard, a printing head and a piler used for receiving a printed cardboard. Differential air pressure is imposed by a suction box that is arranged near a conveyor belt used for transmitting the cardboard. The size of the suction box can be fixed so that the length and size of the cardboard can be orientated along the feeding direction. When a plurality of printing heads are adopted, the printing heads are overlapped along a direction that is at landscape orientation of the moving direction of the cardboard, thereby forming an image that is larger than the printing head. Two printing mechanisms that are arranged opposite to each other can be used for printing the two sides of the cardboard.

An image forming device includes an image forming device body having an image forming unit in the interior thereof, and at least one paper tray attached to the image forming device on which paper is to be mounted. The paper tray includes a paper mounting unit having a paper mounting surface on which paper is to be mounted, and at least one movable auxiliary mounting unit. The auxiliary mounting unit is supported by the paper mounting unit, and includes an auxiliary mounting surface that is deployed from the paper mounting unit and which serves to extend the mounting surface. The brightnesses of the mounting surface and the auxiliary mounting surface of the paper tray are lower than the brightness of the paper to be mounted on each mounting surface, and the brightness of at least a portion of the auxiliary mounting surface is higher than the brightness of the mounting surface.

A paper feeder for feeding paper in an image forming apparatus is disclosed. The paper feeder includes multiple manual paper feed openings and multiple manual paper feed parts positioned corresponding to the manual paper feed openings. The manual paper feed openings and the manual paper feed parts are provided in the main body of the paper feeder.

Provided are a paper feeding device that can stably feed one sheet of paper at a time to a paper feeding unit hopper of a printer or die cutting device. A paper feeding device (1) comprising a paper feeding tray (10) on which a plurality of sheets (60) are stacked in the vertical direction, a sheet feeding means (20) that sends, in the horizontal direction, the sheet (60) that is located at the top of the plurality of sheets (60) stacked on the paper feeding tray (10), and a pair of feeding rollers (30) that deliver the sheet (60) by grasping the leading edge of the sheet (60) that is sent by the sheet feeding means (20), wherein the feeding rollers (30) are variable speed rollers for which the circumferential speed can be increased and decreased while sending one sheet (60) from the leading edge to the trailing edge.

A sheet conveying device, that can be included in an image forming apparatus, includes a first sheet conveying path, a second sheet conveying path, a third conveying path, and a belt-type sheet conveying unit. The first sheet conveying path has a curved portion, and feeds and conveys a sheet therethrough. The second sheet conveying path has a curved portion and different from the first sheet conveying path, and feeds and conveys the sheet therethrough. The third sheet conveying path is provided from a confluence of the first sheet conveying path and the second sheet conveying path. The belt-type sheet conveying unit is disposed on one side of the third sheet conveying path corresponding to an outer side of the curved portion of the first sheet conveying path and an inner side of the curved portion of the second sheet conveying path.

An entrance guide for externally fed sheet (4) to printer (1) is configured to bow the sheets. In one embodiment guides (5a, 5aa) within slot 7 have upper and lower configurations which force sheet into a bow. In one embodiment slot (7a) is bowed and is sufficiently narrow in height to only accept a bowed sheet. The bowed sheets do not sag against the printer (1), which aids in sheet registration.

A sheet conveying device may include a belt, a fan, and a housing, the belt has a plurality of through holes, the fan is arranged so that a portion of the belt at a return running position intervenes between the fan and the belt at a forward running position Between portions, the housing and the portion of the belt in the forward running position define a chamber. The fan creates negative pressure within the chamber by drawing air through the through holes of the endless belt, thereby removing dust and other unwanted particles and debris from the endless belt. In one or more examples, brushes may also be included to provide further removal of unwanted dust and particles. Additionally, in one or more configurations, the sheet transport device may further include belt rollers and / or supports.
