Abstract
A rotary ink jet printer can print at high speed in black and white as well as in color using hot-melt inks. The printer includes a rotary print wheel which supports a plurality of ink jetters distributed around its periphery. The jetters are divided into color groups with the jetters in each group drawing ink from a separate chamber of an ink reservoir with the different chambers containing different-colored inks. Each jetter can be aimed separately from all of the other jetters in the print wheel in a direction parallel to the rotary axis of the wheel as well as in a direction perpendicular thereto and tangent to the print wheel, enabling the jetters in the different groups during each revolution of the print wheel to print in a plurality of colors on a plurality of different lines of a recording medium advancing as a cylinder past the periphery of the print head. A mechanism for automatically aiming the jetters on the print wheel is also disclosed.
