MFC-L9570CDW
The 7-inch color touchscreen is the first hint that the Brother MFC-L9570CDW runs a front office, not just a print queue. This multifunction pairs the HL-L9310CDW's 33 ppm engine with an 80-sheet ADF that scans at 52 ipm simplex and 104 ipm duplex, plus a 33.6Kbps Super G3 fax for paper workflows that refuse to die. It shares the same TN431/TN433/TN436/TN439 cartridges and DR433CL drum, and its 80,000-page maximum monthly duty cycle takes the heaviest document days in stride.

Frequently Asked Questions
Which toner does the Brother MFC-L9570CDW use?
The MFC-L9570CDW uses the Brother TN431 standard-yield series (black ~3,000 pages, each color ~1,800 pages), the TN433 high-yield series (black ~4,500 pages, each color ~4,000 pages), the TN436 super high-yield series (~6,500 pages black and color) or the TN439 ultra high-yield series (~9,000 pages black and color), paired with the Brother DR433CL drum unit (~50,000 pages).
What is the difference between the TN431, TN433, TN436 and TN439?
All four fit the same printer — they are a yield ladder. The TN431 is the standard-yield cartridge, the TN433 prints more per cartridge, the TN436 more again (~6,500 pages), and the TN439 is the ultra high-yield option at about 9,000 pages per cartridge. Higher yield means a lower cost per page for high-volume printing.
Are the cartridges on this page original or compatible?
Both — this page carries compatible TN431, TN433, TN436 and TN439 replacements as well as genuine Brother OEM toner cartridges in all four series and the genuine Brother DR433CL drum.
How long does the DR433CL drum last?
About 50,000 pages — many toner changes between drum replacements.
