Abstract: A mid-frame for use in an imaging apparatus includes an undulating surface extending in an undulation direction. At least one elongated slot can be formed in the mid-frame, wherein a direction of elongation of the elongated slot is substantially the same direction as the undulation direction.

Abstract: An easily transportable ink jet printer apparatus provides a chassis that includes an ink jet print head having nozzles for dispensing ink, the print head being movably mounted to the chassis along the travel path. The chassis also includes a paper output tray movably mounted to the chassis between printing and carrying positions. The print head has a parked position at a selected position along the travel path when not printing in which the nozzles are capped to prevent clogging of the nozzles by dried ink. A locking member is movably mounted to the chassis between carrying and printing positions. The locking member holds the print head in the parked position when moved into the carrying position. The locking member can also be used to lock other components such as paper storage tray, paper exit tray, and cover. The locking member can be a handle with a gripping surface thereon, enabling a user to grasp and lift the handle to a transport position that secures a component or components of the printer (e.g.
