Abstract: Air filter and cable management assemblies for network communication systems are disclosed. The assemblies include filters that cover one or more communication line cards and their associated connection panels. The assemblies also include cable support structures with cable support brackets that support connected cables while restricting airflow so that airflow is forced through the filter towards the connection panels. This airflow can then pass into housings for the line cards and other circuitry, such as fabric cards, to provide desired cooling. Fan subsystems can also be provided to facilitate airflow. Advantageously, the disclosed air filter and cable management assemblies allow for filtered cooling of stacked network communication systems while greatly simplifying the complexity of the filter and cable installation and maintenance.

Abstract: According to the present disclosure, a printer apparatus may include a chuck configured to support a substrate thereon, a rail spaced apart from the chuck, a printhead carriage frame coupled to the rail, and a printhead carriage coupled to the printhead carriage frame. The printhead carriage may include a printhead and an actuation mechanism. The actuation assembly may be coupled to the printhead carriage and may be selectively engagable with the printhead for selective displacement of the printhead relative to the printhead carriage.

Abstract: An inkjet printer includes a plastic platen and a structural member extending upward from the base of the printer. The printing surface is supported by the upper surface of the structural member. This surface is held flat to within very tight tolerances. The bottom of the platen printing surface is retained against this surface so that it conforms to the shape of this surface structural member to create a substantially flat printing surface.
