There can be one or two high capacity stackers.
Open the Settings Editor and go to: .
Go to the [Stacker] section.
Use the [Top tray - Preferred feed edge] and [Stack tray - Preferred feed edge] settings to indicate if the long or short side of the sheet points refers to the feed direction of the sheets by default.
[Long-edge feed (LEF)]: long-edge feed direction.
[Short-edge feed (SEF)]: long-edge feed direction.
Use the [Top tray—Face orientation] and [Stack tray - Face orientation] settings to indicate if the front side of the prints points up or down by default.
[Face up]: front side of first printed sheet is visible.
[Face down]: back side of last printed sheet is visible.
Use the [Top tray - Header orientation] and [Stack tray - Header orientation] settings to indicate if the header of the prints points to the front side of the printer or to the back side of the printer by default.
[Header-up]: header of printed document pages points to the back side of printer.
[Header-down]: header of printed document pages points to the front side of printer
Use the [Top tray - Preferred sheet order] and [Stack tray - Preferred sheet order] settings to define the default order of the prints.
[Front/back]: the first source file page is printed first.
[Back/front]: the last source file page is printed first.
Use the [Stack tray - Offset stacking] settings to define the offset value. When the offset value is '0' offset stacking is disabled. The default offset value is 15 mm / 0.59".
Use the [Minimum filling level] setting to define the filling level in the stack tray.
The minimum filling rate is a percentage of the maximum stack height. The default value is 80%. The high capacity stacker ejects the stack as soon as the stack height exceeds the minimum filling rate. The minimum filling rate is active in case the high capacity stacker ejects a stack when the stack tray is full.
Use the [Maximum stack height] setting to define the maximum stack height in the stack tray.
The default stack height is 302 mm / 11.9". The minimum stack height is 10 mm / 0.39". The maximum stack height is 345 mm / 13.58". When the stack height is larger than the default stack height, there can be a risk that sheets fall off the stack when the eject tray moves out.
