For increased output from your Kyocera laser printer with less time spent changing toner cartridges, install a genuine Kyocera Black Laser Toner Kit (TK320). Order a new toner kit when your printer displays a Toner Low error message and keep it handy. When the current toner cartridge is exhausted, the printer will display Replace Toner and you must install a new cartridge before resuming printing. This higher yield cartridge is packed with enough black toner to print 15,000 pages.
