Paper tray for a printing mechanism

A printer feeder tray comprising:

• a first media guide movable relative to a first wall of the tray in a first direction to vary a first spacing there between for accommodating different media sizes in the first direction,
• a second media guide manually adjustable relative to a second wall of the tray in a second direction substantially perpendicular to the first direction to vary a second spacing there between for accommodating different media sizes in the second direction;
• means for synchronizing movements of the first guide with movements of the second guide so that, adjustment of the first guide is automatically achieved through the manual adjustment of the second guide, said synchronizing means including:
• a rotatable gear interactable with the second guide for transforming linear movements of the second guide in the second direction into rotational movements of the gear, wherein the rotational movements of the gear are further transformed into linear movements of the first guide in the first direction, which is substantially perpendicular to the second direction, and
• a cam coupled to the first guide, wherein the cam is driven by the gear for transforming the rotational movements of the gear into the linear movements of the first guide, and wherein the cam has a predefined profile for positioning the first guide relative to the first wall;
• and
• means for biasing the first media guide towards the first wall so that the first media guide is held in contact with the profile of the cam.
