Frequently Asked Questions

Why does a colour printer need a drum set rather than a single drum?

Because a colour machine images four colours, and each colour needs its own drum surface to print through. The DR331CL is the drum unit set for Brother's TN331/TN336 colour platform: one unit that carries the imaging drums for black, cyan, magenta and yellow together, rated at 25,000 pages. The colours age side by side in the same machine, so Brother engineers them as a single replaceable set — when the set is due, one swap renews the imaging side of all four colours at once instead of chasing four separate parts.

How many toner cartridges does one DR331CL set outlast?

Count it against the platform's cartridges: about ten TN331BK blacks (2,500 pages each) or six TN336BK (4,000 each) on the black side, and on the colour side roughly sixteen TN331 colour cartridges (1,500 each) or seven TN336 colours (3,500 each) per position. However the machine is fed, the drum set is a once-in-years purchase: at $233.21 — $93.28 under its $326.49 list price — it adds under a cent a page (about 0.93 cents) across its rated life.

What symptoms say the drum set, rather than a toner cartridge, is failing?

Defects that repeat at the same spacing on page after page are the classic sign, along with background shading in areas that should stay white. On a colour machine there is a second clue: if one colour starts leaving repeating marks while its toner cartridge is fresh and full, that colour's drum surface — inside this set — is the suspect, not the cartridge. Swapping toner will not move a drum defect; it follows the set until the set is changed.

Which printers does the DR331CL serve?

Five models: the HL-L8250CDN, HL-L8350CDW and HL-L8350CDWT printers, and the MFC-L8600CDW and MFC-L8850CDW all-in-ones. Those machines run the TN331 standard-yield and TN336 high-yield toner families, and the DR331CL is the one drum set the whole platform shares — toner tiers differ, the drum set does not.

Do I have to change all four toner cartridges when I change the drum set?

No. The drum set and the toner cartridges are separate parts on separate clocks. Your existing TN331 or TN336 cartridges lift out of the old drum unit arrangement and go back in with the new DR331CL, keeping whatever toner remains in them. Change the set when the machine's drum warning appears or print defects say the surfaces are tired — and reset the drum counter in the menu afterwards so the printer tracks the new set's life from zero.

What returns and warranty cover apply to this drum set?

The OEM arrangement: a 30-day return window that applies in all cases, and warranty cover provided by Brother's manufacturer warranty, since this is a genuine Brother part throughout. The complete wording is on our shipping and returns page. Fit the set promptly after it arrives, and if anything looks wrong, our support team is available Monday to Friday, 9 AM to 5 PM CST.
