An example printing device includes a memory to store data to print to a print media, a page pick mechanism to pick a page of the print media from a print media source, and a controller connected to the memory and the page pick mechanism. The controller is to control a timing of the page pick mechanism to pick a next page of print media based on a quantification of the data in the memory for a current page.

A sheet conveyance apparatus include a first conveyance unit, a second conveyance unit including a cover and configured to be movable between a first position where a sheet conveyed from the first conveyance unit can be conveyed to a sheet conveyance path and a second position separated from the first position, and a retaining portion configured to retain the cover at an open position and to retain the second conveyance unit at the second position through the cover retained at the open position in a case where the cover is positioned at the open position in a condition in which the second conveyance unit is positioned at the second position.

The conveyor comprises two single-transport-belt conveyor subassemblies (42AL, 42AH) arranged facing each other symmetrically relative to a pinching plane of the conveyor (42A), two sets of rollers (423L, 423H) incorporated in the two conveyor subassemblies and distributed on either side of the pinching plane. A first set of rollers (423L) guides a belt (420AL) of the first conveyor subassembly and a second set of rollers (423H) guides a belt (420AH) of the second conveyor subassembly. The conveyor subassemblies comprise sets of vertically arranged jacks (424L, 424H) which are associated with the sets of rollers, each of the rollers being mounted on a dedicated respective jack.

A medium feeding device includes a feed roller that feeds a medium from a medium placement unit on which the medium is placed a separation roller that nips the medium between the feed roller and the separation roller to separate the medium, a motor that applies a rotational torque to the separation roller, and a control unit that controls the motor. The rotational torque is transmitted to the separation roller from the motor not via a torque limiter and the separation roller separates the medium with the rotational torque applied to the separation roller.
