To be green, Xerox has developed a sophisticated way to deliver ink. The answer? Deliver the ink in solid form.
The solid form is made from a polymeric resin and looks and feels like a square, yellow crayon. Combined with advanced print head technology, this new solid ink is to help make a greener printer. Typically in average desktop printers, the cartridges are filled with liquid ink and inserted into small print heads that race back and forth to transfer an image to paper. Instead the new solid ink is melted, then dripped into a single drum that’s a wide as a standard sheet of paper. The image is then transferred with heat and pressure to paper. It takes approximately 10 revolutions of the drum to transfer the drum, which is then hardened and ejected from the paper.
This version of ink is greener because liquid ink requires a lot more packaging (the cartridge and the box it comes in). Per Xerox, the solid ink outputs 90 percent less waste than liquid ink and saves up to 260 pounds of discarded cartridges and their packaging over the lifetime of one desktop printer.
The solid ink doesn’t require any water or solvent to dry the ink. Although, the process does require more energy to heat thick ink to melt it (melting point is between 70 degrees and 100 degrees Celsius). Xerox will continue to research and develop new insulation techniques to minimize energy needed to heat the ink.
