The MFC-L8900CDW is a business color laser all-in-one: print, copy, scan and fax at up to 33 pages per minute, a 70-page single-pass duplex document feeder, automatic two-sided printing, 300 sheets of paper input (a 250-sheet tray plus a 50-sheet multipurpose tray), expandable to 1,300 sheets with optional trays, and Wi-Fi, Gigabit Ethernet and NFC. Brother has discontinued it, but it remains common in small offices, and its toners are shared with several current models.
TN431 vs. TN433 vs. TN436: Which Should You Buy?
All three capacities are the same physical shape and can be mixed — for example, a TN436 black alongside TN433 colors. The bigger the cartridge, the lower the cost per page. Most offices are best served by TN436 for the colors they use most and TN433 where they print less. The standard TN431 rarely makes sense on a machine this size. Use our printer ink cost calculator to compare at your volume.
Watch out for TN437 and TN439: Brother makes even bigger cartridges, but neither is listed for the MFC-L8900CDW. TN437 is listed only for the MFC-L8905CDW, and TN439 is made for other models. TN436 is the largest size for this printer.
Buying TN433 and TN436 Toner at Castle Ink
Shop high-yield TN433BK, TN433C, TN433M and TN433Y, or super-high-yield TN436BK, TN436C, TN436M and TN436Y — or get all four colors in the TN436 4-pack. These are newly manufactured compatible cartridges. Orders placed by 4 PM ET ship the same day, and U.S. orders over $50 ship free. Castle Ink does not stock the DR431CL drum; you can find the DR431CL on Amazon (as an Amazon Associate we earn from qualifying purchases).
The Drum, Belt and Waste Box
Color lasers have more parts than mono lasers. The DR431CL is a single unit holding all four drums and lasts about 30,000 pages. The BU330CL belt and WT320CL waste toner box each last about 50,000 pages. The printer tells you when each one is due — you do not replace them with every toner change. Reset the matching parts-life counter after installing a new drum, belt or waste box.
How to Replace a Toner Cartridge
- Open the top cover / front cover as shown on the display, and wait for the printer to stop moving.
- Pull out the drum unit until it stops (it slides out on rails; you do not remove it completely).
- Push down the green lock lever on the cartridge that needs replacing and lift it out of the drum unit.
- Gently shake the new cartridge side to side, remove the protective cover, and slide it into the matching color slot until it clicks.
- Slide the green tab on each drum's corona wire left and right a few times, returning it to the home position.
- Push the drum unit back in and close the cover.
Troubleshooting Tips
"Replace Toner" or "Toner Low" too soon: Shake the cartridge gently and reinstall it. If you want to run each cartridge further, the Replace Toner setting can be changed to Continue. See how to reset a Brother toner cartridge.
"No Toner" with a new cartridge: Check that the cartridge is seated in the correct color slot and clicked fully. See printer says cartridge not recognized.
Colors look off or a color cast appears: Run Calibration and Registration from the printer's menu. More help in printer printing the wrong colors.
Streaks in one color: Clean that drum's corona wire with the green slider. If a streak repeats at a set interval, the drum unit may need replacing.
Which Other Printers Use the Same Supplies?
TN431/TN433 toner and the DR431CL drum also fit the Brother HL-L8260CDW, HL-L8360CDW, MFC-L8610CDW, MFC-L8895CDW and MFC-L8905CDW. Brother lists the super-high-yield TN436 for the MFC-L8900CDW, MFC-L8905CDW, HL-L8360CDW/CDWT, MFC-L8895CDW, HL-L9310CDW and MFC-L9570CDW, but not the HL-L8260CDW or MFC-L8610CDW.
What MFC-L8900CDW owners ask
These are the questions that come up most for this printer on retailer Q&A pages, Brother's support pages and owner reviews, answered in our words.
Will the bigger TN437 toner fit?
Brother lists TN437 (about 9,000 pages black, 8,000 color) only for the MFC-L8905CDW, not the MFC-L8900CDW. On this printer, TN436 at about 6,500 pages is the largest size Brother lists.
How long does the DR431CL drum really last?
Brother rates it at about 30,000 pages if you print one page per job, and about 50,000 at three pages per job. Lots of single-page jobs wear it out sooner.
Did my new printer come with high-yield toner?
No. It ships with standard-yield cartridges rated at about 3,000 pages black and 1,800 pages per color, the same as TN431.
Why do small dots repeat down one side of every page?
That pattern usually comes from debris on one color's drum. Print the Drum Dot Check Sheet to find which one, gently clean that drum and the corona wires, and replace the toner or drum unit if the dots stay.
I fitted a new drum, but it still says Replace Drum. Why?
The printer keeps a separate life counter for the drum, and it has to be reset after a new drum goes in. Brother has a support article for this exact message on the MFC-L8900CDW.
MFC-L8900CDW quirks worth knowing
- It has NFC tap-to-print and a built-in NFC card reader, plus a front USB port for memory sticks and a rear USB port for a card reader.
- Brother rates it at 33 pages per minute only for one-sided printing. It prints two-sided by default, so you have to change that setting to get the rated speed.
- Beyond toner and drum, Brother's message list for this model includes Replace PF Kit, Replace Fuser and Replace Laser, plus belt and waste-box warnings. Those are maintenance parts, not toner problems.
- The WT320CL waste toner box is shared by 17 Brother color lasers, from the HL-L8250CDN to the MFC-L9570CDW.
Frequently Asked Questions
Can I mix TN433 and TN436 cartridges?
Yes. They are the same shape and the MFC-L8900CDW accepts any combination of TN431, TN433 and TN436.
Does the MFC-L8900CDW use TN439?
No. Brother doesn't list TN439 for this printer. Use TN431, TN433 or TN436.
Does compatible toner void the warranty?
No. Under the U.S. Magnuson-Moss Warranty Act, Brother cannot void your warranty only because you used third-party toner.
