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