Abstract
An example method for picking a media sheet from a media tray, the method comprising: controlling a media picker to perform a pick procedure to pick the media sheet from the media tray; upon detecting an error condition in the pick procedure, translating the media sheet in a direction within a plane of the media sheet; and controlling the media picker to retry the pick procedure to pick the media sheet from the media tray.
Claims14
A method for picking a media sheet from a media tray, the method comprising:
- controlling a media picker to perform a pick procedure to pick the media sheet at a first point of contact from the media tray;
- upon detecting an error condition in the pick procedure, translating the media sheet in a direction within a plane of the media sheet, wherein translating the media sheet is performed independently of the media picker by translating the media tray in a direction only horizontally parallel to a plane of the media tray;
- and
- controlling the media picker to retry the pick procedure to pick the media sheet at a second point of contact different from the first point of contact relative to the media tray.
A printer comprising:
- a media tray to contain media for a printing operation;
- a media picker to pick a media sheet from the media tray at a first point of contact when the media tray is in an operational position;
- and
- a media tray transporter to move the media tray only horizontally parallel to a plane of the media tray and away from a separation wall to a retry position when the media picker fails to pick the media sheet, wherein the retry position is different from the operational position;
- and
- wherein the media picker is further to retry picking the media sheet from the media tray at a second point of contact different from the first point of contact while the media tray is in the retry position.
A printer comprising:
- a primary media tray to contain primary media for a printing operation;
- a secondary media tray to contain secondary media for the printing operation;
- a secondary media tray transporter to transport the secondary media tray;
- a media picker to pick a primary media sheet when the secondary media tray is in an unobstructive position and a secondary media sheet when the secondary media tray is in an operational position, the media picker comprising a roller to pick the primary or secondary media sheet in a picking direction towards a separation wall;
- a controller interconnected with the media picker and the secondary media tray transporter, the controller to:
- control the media picker to perform a pick procedure when the secondary media tray is in the operational position to pick the secondary media sheet at a first point of contact;
- upon detecting an error in picking the secondary media sheet, control the secondary media tray transporter to move the secondary media tray to a retry position, wherein the retry position is different from the operational position;
- and
- control the media picker to perform the pick procedure when the secondary media tray is in the retry position to pick the secondary media sheet at a second point of contact different from the first point of contact.
