A media tray may include a number of mezzanines to accumulate media as the media is ejected from a printing device and a number of ramps to selectively engage with a leading edge of the media as the media is accumulated based on a plurality of positions of the number of ramps, the number of ramps positionable based on movement of the number of mezzanines. In one example, movement of the number of mezzanines from a first position to a second position may cause the number of ramps to be in a position to selectively engage and disengage with a leading edge of the media.

Systems and methods for folding a stack of substrate sheets are provided. The system may include a roller assembly and a positioning mechanism. The roller assembly is configured for folding the stack of substrate sheets and the positioning mechanism is configured to position the substrate or stack for entry into the roller assembly. The positioning mechanism includes an upper curved for and a lower curved form to guide the stack of substrate sheets into a curved position for folding. The positioning mechanism further includes a folding blade positioned to extend through the gap between the upper and lower curved forms. The roller assembly can move the folded stack of substrate sheets in at least two directions.

An image forming apparatus comprises a first conveyance unit, an image forming unit, a second conveyance unit, a stacking unit, and a control unit. The control unit controls, in a case where a sheet stacking condition of the stacking unit does not satisfy a predetermined stacking condition, the second conveyance unit to convey the sheet at a second conveyance speed that is faster than the first conveyance speed. The control unit controls, in a case where the sheet stacking condition of the stacking unit satisfies the predetermined stacking condition, the second conveyance unit to convey the sheet at a third conveyance speed that is slower than the second conveyance speed.

Features for systems and methods for loading items into a tray are disclosed. The system may have an item conveyor configured to move the items towards a tray conveyor. The tray conveyor may be configured to move trays to receive items from the item conveyor into the tray. One or more sensors may detect the height of the items on the item conveyor and/or in the tray, and/or the position of the trays on the tray conveyor. A controller may receive data related to the one or more detected heights of the items and/or the position of the trays on the tray conveyor and correspondingly control movement of the item and/or tray conveyors for efficient loading of items into the tray and efficient movement of the trays for further processing. Tray conveyor movement sensors may detect movement of the trays or tray conveyors for further control or reliability of the system.

In accordance with an embodiment, a sheet processing apparatus comprises a first tray, a second tray, a third tray, a lower supporting plate, a drive section and a control device. The second tray is located at the lower part of the first tray. The third tray is located at a downstream side with respect to the second tray in a sheet conveyance direction. The lower supporting plate can support the sheet from the lower part. The drive section drives the lower supporting plate. The control device controls the drive section to arrange the lower supporting plate at the downstream side with respect to a conveyance starting point of the sheet in the sheet conveyance direction in a case of skipping the first tray and the second tray to convey the sheet to the third tray.
