Abstract: An image forming apparatus is provided. The image forming apparatus includes a printing engine, a paddle device, a stapler device, and a processor. The printing engine is to form an image on a printing paper. The paddle device is to move the printing paper ejected from the printing engine in a moving direction to align a first end of the printing paper. The stapler device is to staple the align printing paper. The processor is to control the paddle device and the stapler device to move a second end of the aligned printing paper in an opposite direction to the moving direction when the first end of the printing paper is aligned.

Abstract: Example systems are disclosed for printing an image. In one example, the system includes a printhead assembly including a plurality of printheads to deposit printing fluid on a print media as the printhead assembly is moved across the print media along an arcuate path. In addition, the system includes a controller assembly communicatively coupled to the printhead assembly, wherein the controller assembly is to adjust a timing of printing fluid deposition onto the print media from the plurality of printheads based on relative positions and orientations of the printheads along the arcuate path.

Abstract: A knockdown apparatus for a finisher includes a register tray, a paddle coupled to a rotatable shaft to compile a recording medium toward an end of the register tray, and a knockdown device, provided above the register tray, to rotate to apply a downward force to the recording medium while the recording medium is in the register tray to decrease a curl in the recording medium.

Abstract: An paddle apparatus for a finisher includes a rotatable shaft and a paddle coupled to the rotatable shaft. The paddle is rotatable in a forward direction to compile a recording medium toward an end of a register tray of the finisher, and is rotatable in a reverse direction to apply a downward force to the compiled recording medium. An amount that the paddle is rotated in the reverse direction can be varied based on a height of the compiled recording medium in the register tray.

Abstract: According to an example, printed media stack alignment may include actuating a belt and a paddle to shift first and second sheets to a stopper position represented by register of the first and second sheets against a stopper. The stopper may be actuated to shift the first and second sheets to an eject position, where the eject position is intermediate to a sheet deposit position and the stopper position. The belt and the paddle may be actuated to shift the first sheet, the second sheet, and a third sheet received at the sheet deposit position to the stopper position. The stopper may be actuated to shift the first, second, and third sheets to the eject position. Further, an ejector may be actuated to eject a stack including the first, second, and third sheets from the eject position.
