Abstract
A rack-and-pinion print media guide system comprises two racks which are operatively coupled for reciprocal movement relative to each other by way of a central gear cluster instead of a single central gear (pinion) to expand the maximum media capture range. The gear cluster comprises first and second pinions and at least one center idler gear which is operatively coupled between the pinions with each rack skipping the center idler gear during operation.
Claims30
A media guide system, comprising:
- (a) a first rack;
- (b) a second rack disposed opposite said first rack, said first and second racks adapted to move in a reciprocal fashion relative to each other to afford a maximum media capture range;
- and
- (c) at least one central gear cluster operatively coupled between said first and second racks to expand said maximum media capture range.

A media guide system, comprising:
- (a) a first pinion adapted to rotate on a first post;
- (b) a second pinion disposed proximate to said first pinion and adapted to rotate on a second post;
- (c) a first rack operatively coupled to said first pinion;
- (d) a second rack operatively coupled to said second pinion, said first and second racks adapted to move in a reciprocal fashion relative to each other to afford a maximum media capture range;
- and
- (e) at least one idler gear operatively coupled between said first and second pinions to form a central gear cluster, said central gear cluster expanding said maximum media capture range.

A print media guide system, comprising:
- (a) a base frame;
- (b) a first print media guide member operatively coupled to said base frame and including a first rack;
- (c) a second print media guide member operatively coupled to said base frame opposite said first print media guide member and including a second rack,
- said first and second print media guide members adapted to hold a print media roll mounted therebetween,
- said first and second racks adapted to move on said base frame in a reciprocal fashion relative to each other to afford a maximum media capture range;
- and
- (d) at least one gear cluster disposed substantially centrally between said first and second print media guide members,
- said at least one gear cluster operatively coupled between said first and second racks to expand said maximum media capture range.
