Abstract
An imaging apparatus is provided including a frame having a portion upon which a printhead is adapted to be mounted. The printhead may include a housing including a main body, at least one flexible mounting beam extending from the main body, and at least one structural member coupled to the at least one flexible mounting beam. The printhead may also include a skew correction mechanism mounted to the printhead housing. The skew correction mechanism may include an adjustment member capable of engaging at least one surface on the printhead housing so as to adjust the position of the printhead housing relative to the frame portion.
Claims18
An imaging apparatus comprising a frame having a portion upon which a printhead is adapted to be mounted, said printhead comprising:
- a housing including a main body, at least one flexible mounting beam extending from said main body, and at least one structural member coupled to said at least one flexible mounting beam;
- and
- a skew correction mechanism mounted solely to said printhead housing, said skew correction mechanism including an adjustment member capable of engaging at least one surface on said printhead housing main body so as to adjust the position of said printhead housing main body relative to said frame portion.
An imaging apparatus comprising a frame having a portion upon which a printhead is adapted to be mounted, said printhead comprising:
- a housing including a main body, at least first and second flexible mounting beams extending from said main body, and at least one structural member comprising a first substantially rigid structural member coupled to said first and second flexible mounting beams;
- and
- a skew correction mechanism associated with said printhead housing, said skew correction mechanism including an adjustment member capable of engaging first and second surfaces on said printhead housing main body so as to adjust the position of said printhead housing main body relative to said frame portion, said adjustment member comprising a camshaft and first and second cam lobes coupled to said camshaft, said first cam lobe being adapted to engage said first surface on said printhead housing main body and said second cam lobe being adapted to engage said second surface on said printhead housing main body.
An imaging apparatus comprising a frame having a portion upon which a printhead is adapted to be mounted, said printhead comprising:
- a housing including a main body, at least one flexible mounting beam extending from said main body, and at least one structural member coupled to said at least one flexible mounting beam;
- and
- a skew correction mechanism associated with said printhead housing, said skew correction mechanism including an adjustment member including first and second camming members capable of engaging first and second cam follower surfaces on said printhead housing main body so as to adjust the position of said printhead housing main body relative to said frame portion.
