An image-related device has an image-medium receiving tray. The tray is designed by a method that enables the tray to control the contouring of sheets of image medium during reception. The tray has a planar surface and a curved surface. The curved surface is designed by selecting a series of transverse and longitudinal curves to define a curved surface that is generally concave in the transverse direction while also sloping upward in the longitudinal direction. The combined concave and sloped shape of the curved surface causes the leading-edge region of the image medium to transversely curl and thereby obtain sufficient rigidity to extend beyond the front end of the tray. In addition, the curved surface--operating in conjunction with the kickout mechanism of the device--interacts with sheets of medium in a way that causes the sheets to land on top of each other instead of sliding against each other, thereby reducing the possibility of smearing while at the same time producing a neat, evenly stacked pile of media.

In a mounting system for an assembly in a high-frequency desktop device, a chassis element ('element') provides ground. For best ground, features formed in the element near a first edge of the assembly force the two together with no fastener there. Fasteners or other provisions secure the assembly, near its second edge, to the element. The features capture the first edge at installation; the fasteners etc. secure the assembly, near its second edge so that the features pinch the first. In another form of the system (1) first raised shapes formed in the element support the assembly near its first edge; (2) features, also formed in the element next to the first shapes, engage and capture the first edge; (3) second raised shapes, formed in the element, support the assembly near its second edge; and (4) fasteners etc. secure the assembly, near its second edge. Preferably the features are so spaced above the first raised shapes as to slightly flex the assembly; no separate fastener holds the assembly to the element near the first raised shapes; the first or second shapes, or both, are metallic and engage grounding pads; and the element is formed metal, structurally integrated with other chassis and case pieces. In another form, the invention is an entire image-related device including the stated items. A method installs and removes the assembly with just one-side access: inserting its first edge between the retainers and first raised shapes, rotating it to operating position to engage it with the second raised shapes near a second edge and pinch the first edge between the retainers and first raised shapes, and securing it--or reversing the steps to remove it.

The invention protects a printer, scanner, copier and/or FAX machine against shock, particularly during shipping and the like. The system includes side covers, and a subsystem to attach them to a major chassis element. Preferably this subsystem omnidirectionally transfers shock between the covers and the chassis element, and includes a hand-in-glove fit of a portion of the chassis element into each cover, with a snap connector holding the chassis element and covers in the hand-in-glove fit. Also preferably a subsystem is included to attach the covers to a main structural assembly. This subsystem is integrally formed in the covers and main assembly, and takes up at least four degrees of freedom of motion between them. Another preferable subsystem attaches the covers to a first major chassis element with omnidirectional transfer of shock loads, and to a second major chassis element with directionally selective coupling of such loads--particularly as between forces generally tangential to the covers and forces generally normal to the covers.
