Document Type and Number:
WIPO Patent Application WO/2020/037551
Kind Code:
A1
Abstract:
A print device comprises a media pickup assembly to feed print media, from a print media stack of an input tray, into a media loading path for printing. The media pickup assembly (106) includes a pickup roller (110) mounted on a rotatable shaft (108) and may include an outer surface (112) to be in contact with the print medium and a slot (114) comprising lateral walls (404) extending from the outer surface towards a central longitudinal axis of the pickup roller. Each lateral wall has an edge meeting the outer surface (112). The edge (408) creates a surface contact between the print media and the pickup roller, to allow the pickup roller (110) to push the print media into the media loading path. A distance between the edge (408) of one lateral wall (404-1) and the edge of another lateral wall (404-2) is in a range of about 2 mm to 3 mm. The distance defines a width of the slot (114).
