The short answer

For a US Brother HL-L2390DW, Replace Drum refers to the DR730 drum, not TN760 toner. If the drum is already new, check its seating and reset its counter with the front cover closed: OK + Up, OK for Drum, then Up. Do not reset an old drum.

For your printer

HL-L2390DW · US · OK and arrow buttons. Confirm whether you changed toner or the drum. If the panel or market differs, use that model’s manual.

Check the toner and drum assembly

Applies to: HL-L2390DW, DCP-L2550DW, MFC-L2710DW, HL-L2395DW, MFC-L2750DW · US

  • Printer is idle. Check the exact model and regional drum number.
Before starting
  • If recently printing, let hot internal areas cool before touching anything. Touch only the designated consumable handles and lever.
  • Keep toner level over disposable paper; do not touch the photosensitive drum surface, use sprays, or open electrical housings.
  1. With the printer on, open the front cover. Allow hot areas to cool.
  2. Use the assembly handle to withdraw the toner-and-drum assembly.
  3. Check that the toner cartridge is locked firmly into the drum carrier; if separated, fit it into the drum until it clicks. Never force a mismatched part.
  4. Slide the assembled unit back into the printer and close the front cover.

Check the result: Check the display. If the message clears, print one test page; no purchase is needed.

If it did not work: If a new drum is installed and Replace Drum remains, continue to the matching reset procedure. If the old drum remains, do not reset its counter.

Install a new drum; keep the toner cartridge

Applies to: HL-L2390DW, DCP-L2550DW, MFC-L2710DW, HL-L2395DW, MFC-L2750DW · US

  • Replace Drum is confirmed, the existing drum has not just been replaced, and the new drum matches the model and market.
Before starting
  • If recently printing, let hot internal areas cool before touching anything. Touch only the designated consumable handles and lever.
  • Keep toner level over disposable paper; do not touch the photosensitive drum surface, use sprays, or open electrical housings.
  1. Leave the idle printer switched on and open its front cover; wait for hot areas to cool.
  2. Withdraw the toner-and-drum assembly by its handle and set it on disposable paper.
  3. Lower the green locking lever, then lift the toner cartridge out of the old drum carrier.
  4. Unpack the new drum when ready to install it. Fit the existing toner cartridge into it until the lock clicks.
  5. Return the complete assembly to the printer and shut the front cover.
  6. Now follow the reset procedure for your exact control panel below.

Check the result: After the new drum’s counter reset, check that Replace Drum clears and print a test page.

If it did not work: If the message remains after correct seating and one documented reset, contact Brother with the exact message and SKU. Do not buy a second drum by default.

Reset a new drum: OK / Up panel

Applies to: HL-L2390DW, DCP-L2550DW, MFC-L2710DW · US

  • A NEW compatible drum has been installed, not just new toner.
  • This is an OK / Up-button model. Never use this to conceal wear on an old drum.
Before starting
  • Do not reset the counter for toner replacement or reuse of the old drum.
  1. Switch the printer on and close the front cover.
  2. Hold OK while pressing the Up arrow.
  3. Use OK to choose Drum.
  4. Press the Up arrow again to reset the drum counter.

Check the result: Check whether Replace Drum disappears, then try a test print. Brother’s FAQ does not promise an “Accepted” screen on this model.

If it did not work: If the controls or menu differ, stop. Verify model and seating; if the message persists after this sequence, contact Brother rather than repeatedly resetting.

TONER CARTRIDGEContains toner powderDRUM CARRIERToner locks into this separate assembly
Conceptual diagram: the toner cartridge locks into a separate drum carrier. Replace only the identified component. Illustration, not a test photograph; not to scale. Consult the model manual for actual handles, surfaces and paper paths.

Before you start

  • Confirm the display says drum, not toner.
  • Open the printer and identify the part family printed on the consumable or in the official support page.
  • If you recently replaced toner only, that does not clear a drum-life message.

Decide which branch applies

If only toner was changed, the drum is still the old part. Toner and drum have different jobs and replacement messages. Drum End Soon is not the same message as Replace Drum.

If a new drum was fitted, start with seating and the counter checklist above. If the old drum remains and Replace Drum persists, use the drum replacement checklist.

If Replace Drum remains afterward

Confirm DR730 on the new US drum label, toner locked into the drum carrier, assembly fully seated and front cover closed. Confirm that you completed the OK / Up sequence once after fitting the new drum.

If the message remains, retain the packaging and receipt and contact Brother with the full display wording. Do not repeatedly reset the counter or assume a second purchase will solve it.

Worth avoiding

  • Do not buy TN730 or TN760 toner to clear a Replace Drum message.
  • Do not reset the drum counter to hide a worn drum.
  • Do not assume every third-party drum will be accepted after firmware updates.
