Abstract
A head positioning adjustment mechanism for an ink jet printer includes a carriage, which moves within the printer and a print head having an engagement portion and nozzles. The carriage includes a head positioning surface for determining a head position in a direction of paper feed, and a head guide groove, which engages the engagement portion of the head. The head includes an abutment surface for contacting the head positioning surface, and is biased against the head positioning surface by a spring. The nozzles are adjusted to a position parallel to the paper feed direction by interposing a rotation correction plate between the abutment surface and the head positioning surface.
