The HL-L3290 series also has duplexing built in. New printers in this series come with CMYK starter toner cartridges which are rated for 1000 pages.

There are two different toner cartridges available for these machines. The TN-223 cartridges are rated for 1,300 pages (1400 BK), and the TN-227 cartridges are rated for 2300 pages (3,000 pages BK). The drum unit (C,M,Y,BK) which will be covered in separate instructions is rated for 18,000 pages. There are different part numbers for these cartridges depending on your region. In North America they are as follows:
