Solid ink printers, also known as phase-change printers, are a type of thermal transfer printer.
They use solid sticks of CMYK-coloured ink, similar in consistency to candle wax, which are melted and fed into a piezo crystal operated print-head.The printhead sprays the ink on a rotating, oil coated drum. The paper then passes over the print drum, at which time the image is immediately transferred, or transfixed, to the page.
Solid ink printers can produce excellent results.
Drawbacks of the technology include high energy consumption and long warm-up times from a cold state.
Also, some users complain that the resulting prints are difficult to write on, as the wax tends to repel inks from pens, and are difficult to feed through automatic document feeders, but these traits have been significantly reduced in later models.
In addition, this type of printer is only available from one manufacturer, Xerox, manufactured as part of their Xerox Phaser office printer line.
Previously, solid ink printers were manufactured by Tektronix, but Tek sold the printing business to Xerox in 2001.Źródło: https://en.wikipedia.org/wiki/Printer_(computing)
Printouts made using this type of printers have vivid and clear colors, which is why they are bought by the most specialized photocopying and printing facilities.
There are also pages with tips for people who work at photocopying points or make a large number of private printouts. .
