Printer and dual trays for image receiver media sheets
View Patent ↗A printer having a sheet tray, a drive for advancing sheets past a marking mechanism, and a picker to remove sheets from an aligned tray includes a load position and a pick position. The trays are selectively moved between the load and pick positions. A transmission is engagable to connect the drive to the tray moving mechanism, whereby the tray is moved between the pick position and the load position by the media sheet advancing drive. The transmission is disengagable to enable advancement of the media sheets without movement of the tray. Starting with both trays in their load positions, one of the trays is moved to its pick position whereat a sheet can be picked; moving the other of the trays to its pick position whereat a sheet of media from each of the trays can be picked; and moving the tray remaining at its pick position from its pick position to its media load position.
1. A printer comprising:
a marking mechanism for producing an image on media;
a tray for sheets of image receiver media;
a sheet feeding mechanism including a drive for advancing the sheets of image receiver media past the marking mechanism, said sheet feeding mechanism having a picker to remove the sheets of image receiver media from an aligned tray;
a media load position at which the tray is accessible to an operator for inserting a supply of the sheets of image receiver media;
a media pick position at which the tray is aligned with the picker;
a tray moving mechanism adapted to selectively move the tray between the media load position and the media pick position; and
a transmission (1) engagable to connect the drive of the sheet feeding mechanism to the tray moving mechanism, whereby the tray is moved between the pick position and the media load position by the drive and (2) disengagable to enable advancement of the sheets of image receiver media without movement of the tray.
2. A printer as set forth in claim 1 wherein the tray moving mechanism is a rack and pinion.
3. A printer as set forth in claim 1 wherein
the transmission has a forward engagement state and a backwards engagement state such that the tray is moved in one direction when the transmission is in the forward engagement state and is moved in another direction when the transmission is in the backwards engagement state.
