On the printing process
The printer is a dye sublimation printer
using an ink ribbon printing process.
As illustrated below, the ink ribbon is made
up of three colored panels (yellow,
magenta, and cyan), and one clear
lamination panel for overcoating.
When printing begins, the thermal print
head heats up as it passes over the film,
causing the dyes to vaporize and permeate
the surface of the print paper. After yellow,
magenta, and cyan have been laid onto the
print paper, the final cycle lays the laminate
layer, which protects the printed surface.
These four-panel printing cycles are
required for each print.
An ink ribbon contains 40 sets of four
panels. After you print 40 sheets of print
paper, the ink ribbon also runs out.
Printing process flow
Until printing finishes, yellow, magenta, cyan, and
transparent laminate layers are processed as

PNotes
• During printing, print paper moves back and
forth along the thermal head of the printer,
which is why the print paper is partially ejected
several times from the rear and front paper
outlets.
• After the final cycle of laminate layer finishes,
the print paper is ejected from the paper eject
slot.
