Embodiments of the present invention provide a microstrip-coupled dipole antenna. The cover component is moveable with respect to the body component, so as to provide an image or functional change in the component being presented to a user of the apparatus, when the user moves the cover component, so as to cover or uncover the body component. The overall weight of the door is about 20 pounds and the door is about 35 mm thick. Cross-communication between subsystems is managed by the central processor. Therefore, crosstalk caused by a back flow of ink and transmission of a pressure wave can be prevented during ejection of ink.
