Abstract
A removable media input tray for holding a stack of media sheets is provided. The input tray is configured so that it can be fitted into a chassis of a printing apparatus. The input tray includes a reference guide wall and at least two datum members movably attached to the reference guide wall. The reference side wall is formed with at least two openings through which portions of the datum members extend. The input tray also includes a width adjuster, which is configured to bias the stack of media sheets against the datum members. The datum members are brought into contact with a side wall of the chassis when the input tray is inserted into the chassis, thereby causing the datum members to be aligned to the same side wall.
Claims13
A removable input tray for supporting a stack of media sheets, said input tray comprising:
- a reference guide wall having at least two openings;
- at least two datum members movably attached to the reference guide wall such that portions of the datum members extend through said openings, said datum members being movable from side to side in a direction substantially perpendicular to the reference guide wall;
- and
- a width adjuster movable toward and away from the reference guide wall, said width adjuster being configured to bias a stack of media sheets against the datum members,
- wherein said datum members are movably attached to the reference guide wall further such that said datum members are permitted to jiggle from side to side in the direction substantially perpendicular to the reference guide wall.
A printing apparatus comprising:
- a chassis having two opposing side walls;
- and
- a removable input tray for supporting a stack of media sheets, said input tray being removably insertable between the two side walls of the chassis, said removable input tray comprising:
- (i) a reference guide wall having at least two openings;
- (ii) at least two datum members movably attached to the reference guide wall such that portions of the datum members extend through said openings, said datum members being movable from side to side in a direction substantially perpendicular to the reference guide wall;
- and
- (iii) a width adjuster movable toward and away from the reference guide wall, said width adjuster being configured to bias the stack of media sheets against the datum members,
- wherein, when the input tray is inserted into the chassis, the reference guide wall is positioned adjacent to one side wall of the chassis and the datum members are brought into contact with the same side wall, thereby causing the datum members to be aligned to the same side wall,
- and wherein said datum members are movably attached to the reference guide wall further such that said datum members are permitted to jiggle from side to side in the direction substantially perpendicular to the reference guide wall.
