Abstract
A carriage (66) of an ink jet printer (60) mounts multiple print heads (10) in a non-colinear arrangement. Preferably, the carriage (66) provides four print head pockets (80) disposed at the corners of a rectangle, each of which pockets (80) receives one of the print heads (10). The print heads (10) are precisely located in the pockets (80), and two print heads (10) pass over alternating swaths of the printing medium during each traverse of the carriage (66). Each print head (10) ejects one or more colors in a pattern of dots during each pass.
