ABSTRACT:
Apparatus for color printing for installation in a printer having a platen, a carriage, a printing head mounted on the carriage, a mechanism for moving the carriage along parallel to the platen and a control for actuating the print head so that the print head can print on a printing medium engaged on the platen employs a guide for guiding a segment color-banded ink ribbon between the printing means and the platen parallel to the platen so that, when actuated, the print head prints indicia in a color corresponding to the ribbon segment color band located opposite the print head. The apparatus also includes a rigid beam pivotally connected to the guide, the pivotal connection being displaced along the beam from the beam transverse centerline. First and second pivots are connected adjacent to opposite ends of the beam. There is also a first lifter for lifting the first pivot to at least one elevation so that the beam is swung up about the second pivot thereby raising the ribbon guide a first selected distance above a reference position and a second lifter for lifting the second pivot to at least one elevation so that the beam is swung up about the first pivot thereby raising the guide a second distance above the reference position, said beam and guide being lifted to a third selected position above the reference position when both pivots are lifted.
