An example stacking system comprises a stacking member movable between a first position in which the stacking member is configured to partially support a first stack of printed substrates, and a second position in which the stacking member is disengaged from the first stack. A receptacle positioned below the stacking member is configured to hold a second stack of printed substrates. A controller is configured to cause the stacking member to move between the first position and the second position when the first stack satisfies a criterion, thereby depositing the first stack into the receptacle on top of the second stack.

A printing apparatus can prevent a print medium from buckling during discharging. In a case in which the print conveyance speed determined by the print mode is higher than or equal to a specified speed, the print medium after printing is conveyed to a discharging tray at the print conveyance speed, and in a case in which the print conveyance speed determined by the print mode is lower than the specified speed, the print medium after printing is conveyed to the discharging tray at the specified speed increased from the print conveyance speed.

A sheet discharging apparatus includes a first detecting portion provided in an apparatus body and configured to detect a move of a movable member in a state where a movable tray is at an upper limit position in a moving direction of the movable tray, wherein a detection result of the first detecting portion changes depending on a position of the movable tray in the moving direction. In addition, a second detecting portion detects the position of the movable tray in the moving direction, and a control portion, in a case where the second detecting portion detects that the movable tray is at the upper limit position, determines whether a sheet is present on the movable tray based on the detection result of the first detecting portion. When the second detecting portion does not detect that the movable tray is at the upper limit position, the control portion determines that a sheet is present on the movable tray regardless of the detection result of the first detecting portion.

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.

Example output assemblies for a printer device and printer devices incorporating the output assemblies are disclosed. In one example, the output assembly includes a support surface to support print media that is dispensed from the printer device along a feed direction. In addition, the output assembly includes a side surface that is coupled to the printer device and disposed above the support surface. The side surface is to transition between a first position and a second position. When the side surface is in the second position, the side surface is extended away from the printer device in the feed direction from the from the first position.

A medium ejection apparatus including: a placement mount on which media are placed; a medium-leading-edge position restriction part that moves between a restriction position at which the restriction part restricts a position of a leading edge portion of a medium ejected toward the placement mount with reference to an ejection direction of the medium and a retracted position retracted from the restriction position; and a medium position control unit that controls the medium-leading-edge position restriction part such that the medium-leading-edge position restriction part performs a leading-edge restriction operation of moving from the retracted position to the restriction position and moving from the restriction position to the retracted position when the medium-leading-edge position restriction part and an upper surface of a medium are not in contact with each other.

A sheet discharge device includes at least one sheet discharge tray, a sheet discharge position adjustment actuator, and a controller. The sheet discharge tray receives discharged sheets. The discharge position adjustment actuator adjusts discharge positions of the discharged sheets on the at least one sheet discharge tray. The controller compares a first rotation amount of first print data printed on a first sheet with a second rotation amount of second print data printed on a second sheet. In response to a determination that the first rotation amount is different than the second rotation amount, the controller controls the sheet discharge position adjustment actuator to (a) discharge the first sheet to a first discharge position and (b) discharge the second sheet to a second discharge position different than the first discharge position.

A sheet processing apparatus includes a stapler, a translating actuator, a rotating actuator, and a controller. The stapler is configured to bind a plurality of sheets together. The translating actuator is configured to translate the stapler. The rotating actuator is coupled to the translating actuator and configured to rotate the stapler. The controller is configured to (a) receive an instruction input, (b) determine a target position and a target angle of the stapler based on the instruction input, (c) control the translating actuator to move the stapler to the target position, (d) control the rotating actuator to rotate the stapler to the target angle, and (e) control the stapler to bind the plurality of sheets together while the stapler is at the target position and the target angle.
