An image forming apparatus includes a controller that receives a print job, which includes the sheet type and print settings of simplex printing or duplex printing. A sheet stacked on a feeding unit is discharged to a discharge portion with an upper surface of the sheet facing different directions in duplex printing and in simplex printing in a first mode, and the sheet stacked on the feeding unit is discharged to the discharge portion with the upper surface of the sheet facing the same direction in the duplex printing and in the simplex printing in a second mode.

A first transport unit transports, along a first path, a sheet transported from an image forming unit. A second transport unit transports the sheet along a second transport path branched from a junction with the first transport path. A first cover, when open, holds the sheet transported to an exterior of a housing and, when closed, partially constitutes the second transport unit. A flap is disposed at the junction and, when at a first position, blocks the second transport path and guides the sheet along the first transport path and, when at a second position, blocks the first transport path and guides the sheet along the second transport path. A drive unit moves the flap between the first position and the second position. A moving mechanism moves away from the flap in response to closing of the first cover, and pushes and moves the flap to the second position.

A liquid discharge apparatus includes a conveyance path, a liquid discharge head, and a drying device. A medium is to be conveyed on the conveyance path. The liquid discharge head discharges liquid onto the medium conveyed on the conveyance path. The conveyance path includes a switchback path and an ejection path. The switchback path switches back a conveyance direction of the medium onto which the liquid has been discharged. The ejection path conveys the medium onto which the liquid has been discharged to an ejection port. The drying device dries the medium both on the switchback path and on the ejection path.

An image forming apparatus includes a main casing including an image forming unit and a discharge tray, and an optional device configured to be removably attached to the main casing. The main casing includes a conveying path through which a sheet is conveyed from the image forming unit, a discharge path through which the sheet is conveyed toward one of the discharge tray and the optional device, the discharge path diverging from the conveying path, and a return path including a first path through which the sheet is conveyed temporarily out of the main casing via an opening formed in the main casing, and a second path through which the sheet is conveyed toward the image forming unit. The first path diverges from the conveying path. The second path diverges from the first path. The optional device is disposed closer to the discharge tray than the opening.

A sheet conveying apparatus includes a paper re-feeding path, a switching member, a reversing roller, a paper discharge roller, a motor, and a revolution control mechanism. The switching member can be switched between a first position and a second position. The reversing roller can reverse a revolving direction thereof between a first revolving direction and a second revolving direction. The paper discharge roller revolves in a third revolving direction for conveying the sheet in a third conveying direction. The motor reverses the revolving direction of the reversing roller and switches the position of switching member by reversing the revolving direction thereof. The revolution control mechanism revolves the paper discharge roller in the third revolving direction with the revolution of the motor, regardless of the reversing of the revolving direction of the motor.

In one example, a system for a inline duplexer media path includes a first print media pathway extending from an input roller to an output roller, wherein the first print media pathway provides the print media through a print zone, and a second print media pathway extending from the output roller to the input roller, wherein the second print media pathway is substantially parallel and separate from the first print media pathway.

A conveyance apparatus includes a change conveyance unit. In a case where a first sheet in a sheet storage unit included in the feeding apparatus is fed in a landscape orientation to the conveyance apparatus, the change conveyance unit changes a conveyance orientation of the first sheet to a portrait orientation. The landscape orientation is an orientation in which a short side of the first sheet is parallel to a sheet conveyance direction of the first sheet. The portrait orientation is an orientation in which a long side of the first sheet is parallel to the sheet conveyance direction. The change conveyance unit changes the conveyance orientation of the first sheet from the landscape orientation to the portrait orientation on a substantially horizontal region between the image forming apparatus and the feeding apparatus.

A conveying apparatus, including: a conveyor mechanism; a housing; a first tray configured to receive a medium conveyed by the conveyor mechanism; an image reader disposed above the first tray, wherein a first discharge opening for discharging the medium outside the housing is formed in an upper surface of the housing so as not to overlap the image reader when viewed from above, and wherein the conveying apparatus further includes: a switcher for switching a destination of the medium selectively between the first tray and the first discharge opening; and a tray unit removably mountable on the upper surface of the housing and including a first introduction opening opposed to the first discharge opening, a second conveyance path for conveying the medium passed the first discharge opening and the first introduction opening, and at least one second tray for receiving the medium conveyed through the second conveyance path.

A first conveyance member reverses a sheet received from a first conveyance path. Second through fourth conveyance members are disposed on a second conveyance path and convey a sheet from the first conveyance member toward the first conveyance path. A restriction portion is capable of restricting driving force of a first driving source from acting on a sheet through the second conveyance member. A controller executes a first operation and a second operation. In the first operation, a second driving source stops driving the third and fourth conveyance members while a first sheet is being nipped at the fourth conveyance member, and a second sheet is conveyed to be abutted with the third conveyance member. In the second operation, the second driving source starts driving the third and fourth conveyance members while the restriction portion restricts driving force of the first driving source from acting on the second sheet.

A paper reversing apparatus includes a main conveyance path, a reversing path, first and second guiding plates and a hardware processor. The reversing path is disposed so as to form a predetermined angle with respect to the main conveyance path. Paper enters the reversing path from the main conveyance path and leaves the reversing path to the main conveyance path by being sent backward. When paper enters the reversing path, the processor moves the first guiding plate to a position for the paper to follow the first guiding plate and moves the second guiding plate to a position to avoid the paper. When paper leaves the reversing path, the processor moves the second guiding plate to a position for the paper to follow the second guiding plate and moves the first guiding plate to a position to avoid the paper.
