An imaging apparatus includes a machine frame unit having a plurality of mounting locations and a pivot location, a printhead base having a first end and a second end, and a first resilient elongate member having a first proximal end and a first distal end. A mounting tab is coupled to the first distal end of the first resilient elongate member, and is coupled to a first mounting location of the plurality of mounting locations of the machine frame unit. A pivot post, having an axis of rotation, pivotally couples a mounting plate to the pivot location of the machine frame unit. An adjustment device is coupled to the machine frame unit, the adjustment device having an engagement member for engaging at least one of the printhead base and the first resilient elongate member to effect a deflection of the first resilient elongate member and a corresponding movement of the printhead base. At least the first resilient elongate member is configured to define a virtual pivot axis for the movement of the printhead base when the mounting tab and the mounting plate are fixedly attached to the machine frame unit. A location of the virtual pivot axis substantially corresponds to a location of the axis of rotation of the pivot post.
