Abstract
Inkjet pens are combined in a printer so that the swaths printed by individual pens are combined into a resultant, wide swath that increases printer throughput. The print medium is carried on a drum and advanced through the printer. In a preferred embodiment, sets of two pens, each set having the same color of ink, are carried near the drum with the two pens arranged such that the swath of one pen is adjacent to the swath of the other pen in a direction that is parallel to the drum axis. Also provided is a carriage assembly for carrying the pens in the just mentioned arrangement for combining the swath widths of the individual pens. The components of the carriage assembly are such that two pens of the same color ink are precisely positioned relative to each other, thereby to meet a very close tolerance requirement for arranging two pens of the same color.
