Abstract
An apparatus for actuating a lift plate of a media tray is disclosed herein. An example of the apparatus includes a rocker assembly adjacent the lift plate and a slide assembly coupled to the rocker assembly to actuate the rocker assembly subsequent to insertion of the media tray in a printing device, thereby raising the lift plate. The apparatus additionally includes a lock assembly to release the lock assembly upon initiation of opening of the media tray, thereby allowing the lift plate to lower prior to such removal. A media tray and method for actuating a lift plate of a media tray are also disclosed herein.
Claims13
An apparatus for actuating a lift plate of a media tray, comprising:
- a rocker assembly adjacent the lift plate;
- a slide assembly coupled to the rocker assembly to actuate the rocker assembly subsequent to insertion of the media tray in a printing device, thereby raising the lift plate,
- wherein the slide assembly includes a ratchet mechanism;
- a lock assembly to secure the slide assembly;
- and
- a latch assembly coupled to the lock assembly to release the lock assembly upon initiation of opening of the media tray, thereby allowing the lift plate to lower prior to such removal.
A media tray, comprising:
- a lift plate assembly to raise and lower media in the media tray;
- and
- an actuation assembly to raise the lift plate assembly subsequent to closing of the media tray within a printing device, to maintain the lift plate assembly in the raised position while the media tray remains closed within the printing device, and to release the lift plate assembly upon initiation of opening of the media tray, thereby allowing the lift plate assembly to lower in an unaided manner under an influence of gravity prior to complete opening of the media tray,
- wherein the actuation assembly includes a camed-surface that interacts with a chassis of the printing device to release the lift plate assembly.
