Edible PrintHead Maintenance: Canon Edible Printer

Edible ink printers are the great medium in converting your digital camera images into edible images.

If your colors are not coming correct or your magenta is not deep magenta, black is printing faded prints, pink prints orange that identifies there is some issue either with your edible ink cartridges or the printhead itself. Edible inks are food-grade coloring made using extracts of sugar and artificial food colors which can crystallize when temperatures either get excessively cool or unused for drawn out stretches of time. If your printer is not yielding hues accurately and your nozzle test is not demonstrating all the cartridge hues obviously, then you will more than likely need to clean your print head.
