Maintain the same high quality and reliability you're used to from your OKI C831 or C841 laser printer by installing a genuine OKI Black Toner Cartridge (44844508). When your printer displays the message 'K Toner Low', the current cartridge is nearly exhausted and you can only print 250 more pages. Order a replacement and swap it for the old cartridge when you see the 'Toner Empty' message. This standard yield toner cartridge is packed with enough black toner to print 10,000 pages.
