The environmentally conscious way to print comes in the form of Solid Ink Sticks. These solid ink sticks, also known as phase change ink or hot melt ink, are composed of toxin-free composites and contain no cartridge for easy, waste-free clean up. The Solid Ink Sticks feel and look much like a crayon, while acting similarly to toners in the LaserJet printing process. First the solid ink sticks are melted down into an aqueous form or liquid when heated to 135 degrees celcius (or 275 degrees Farenheit) before being jetted through printheads onto the photoreceptive drum unit which is at a controlled temperature of 65 degrees Celcius (or 149 degrees Farenheit). Once the molten ink hits the anodized aluminum cylindrical drum unit, it changes to a malleable form which can keep the desired image until transferring to paper when squeezing through the drum and pressure / transfer roller. Once the image is heated and pressed onto the paper, it instantly freezes (or dries) bonding to the paper and leaving behind brighter and more vivid color printouts.
