Black and White Laser Postcards Prints
When compared with the analog photo copiers, monochrome laser printers produce black and white prints by direct scanning of the laser beam. The beam scans across the high quality photoreceptor of the printer. There is yet another feature of the black and white laser printers: it employs an efficient toner cartridge which combines a photo conductor unit that interacts with a waste toner hopper, a toner supply bin and different kinds of gears, blades and rollers. The monochrome laser printers maintain the page count for evaluating the number of pages that are printed since they were first used. A few models also inform users with a reminder message about when the parts need replacement.
