Abstract
In an example printing device may include a tray to receive print media sheets, and a paddle roller to rotate about an axis and move individual print media sheets of the print media sheets to abut an end register of the tray and form a stack of print media sheets, and the paddle roller rotate a first quantity of rotations per print media sheet based in response to a determination that the stack of print media sheets corresponds to a first height.
Claims16
A finishing device, comprising:
- a tray to receive print media sheets;
- and
- a paddle roller to rotate about an axis and move individual print media sheets of the print media sheets to abut an end register of the tray and form a stack of print media sheets, wherein the paddle roller is to:
- rotate a first quantity of rotations per print media sheet in response to a determination that the stack of print media sheets corresponds to a first height;
- and
- rotate a second quantity of rotations per print media sheet in response to a determination that the stack of print media sheets corresponds to a second height greater than the first height, wherein the second quantity of rotations is larger than the first quantity of rotations.

A printing device, comprising:
- a print mechanism to transfer a print substance to print media sheets;
- a media advance mechanism to move the print media sheets from the print mechanism to a finishing zone;
- a paddle roller to rotate about an axis and move individual print media sheets of the print media sheets to abut an end register in the finishing zone;
- and
- a controller to:
- cause the paddle roller to rotate a first quantity of rotations per print media sheet in response to a determination that a stack of print media sheets corresponds to a first height;
- cause the paddle roller to rotate a second quantity of rotations per print media sheet in response to a determination that the stack of print media sheets corresponds to a second height of the stack, wherein the second quantity of rotations per print media sheet is greater than the first quantity of rotations per print media sheet, and the second height is greater than the first height;
- and
- cause the paddle roller to rotate a third quantity of rotations per print media sheet in response to a determination that the stack of print media sheets corresponds to a third height of the stack, wherein the third quantity of rotations per print media sheet is greater than the second quantity of rotations per print media sheet, and the third height is greater than the second height.

A non-transitory machine readable medium storing instructions executable by a processing resource to cause the processing resource to:
- receive signals indicative of a print job;
- set an initial quantity of rotations of a paddle roller per print media sheet for a starting portion of the print job, wherein rotation of the paddle roller is to cause the print media sheet to move to abut an end register of a finishing tray;
- set an intermediate quantity of rotations of the paddle roller per print media sheet for an intermediate portion of the print job, wherein the intermediate quantity of rotations per print media is greater than the initial quantity of rotations per print media, and the intermediate portion of the print job corresponds to a height of a print media stack greater than a height of a print media stack of an initial portion of the print job;
- and
- set a final quantity of rotations of the paddle roller per print media sheet for a final portion of the print job, wherein the final quantity of rotations per print media is greater than the intermediate quantity of rotations per print media, and the final portion of the print job corresponds to a height of a print media stack greater than the height of the print media stack of the intermediate portion of the print job.
