Abstract: In one example in accordance with the present disclosure a media transport device is described. The device includes a number of drive rollers coupled to a frame. A number of media rollers are also coupled to the frame. The media rollers are in contact with, and rotated by, the number of drive rollers. Media rollers in a first set have a first diameter and media rollers in a second set have a second diameter that is different from the first diameter. The device also includes a number of pinch rollers coupled to the frame. The pinch rollers are in contact with the number of media rollers to form a number of nips through which media passes along a feed path.

Abstract: A printing device is described in which there is a media guide that is arranged to guide a printable media substrate from an upstream media path towards an input of the printing device or away from an output of the printing device towards a downstream media path. The media guide is movable between a first position and a second position. In the first position the media guide is arranged to guide the printable media along a respective media path. In the second position, which is spaced apart from the first position, the media guide forms a buffer region into which a variable amount of media substrate can collect.

Abstract: Disclosed herein is a print head maintenance cartridge, a printing device and a method of controlling a wiping subsystem of a print head maintenance cartridge. The print head maintenance cartridge comprises a wiping subsystem with a wiping material to wipe a print head; a clean material roll, wherein a clean part of the wiping material is rolled up on the clean material roll at least in part; a brake to generate a first brake force applied to the wiping material; and a friction element to generate a second brake force applied to the wiping material, wherein the friction element compensates at least in part a change in the first brake force to control a total brake force, wherein the total brake force is the sum of the first and second brake forces.

Abstract: A media stacker (100) comprises a stacking platform (102), a feed mechanism (104), a media arresting mechanism (106) and a controller (108). The feed mechanism conveys media sheets for dispensing onto the stacking platform, wherein the media sheets are dispensed onto the stacking platform with a momentum imparted by the feed mechanism. The media arresting mechanism reduces the momentum of media sheets. The controller determines that a trailing edge of a media sheet is to be dispensed onto the stacking platform, and further control the media arresting apparatus to reduce the momentum of the media sheet in response to the determination.
