Brother HL-L2390DW Drum Reset After Replacing DR730

Clear a persistent drum message after installing a new DR730 in a US HL-L2390DW using the documented OK / Up counter sequence.

The short answer

After fitting a NEW DR730 drum, leave the HL-L2390DW on and close the front cover. Hold OK and press Up, press OK for Drum, then press Up to reset. A toner change alone is not a reason to reset drum life.

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.

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.

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

  • Make sure the installed replacement is a drum unit, not only a toner cartridge.
  • Keep the old drum until the new drum prints correctly.
  • Use the official reset steps for your model rather than a generic menu sequence.

New drum, old warning?

Use this checklist when a new drum is already installed and the old warning remains. If you have not fitted the new drum yet, start with the replacement guide.

What to expect

Check that Replace Drum clears and run a test print. The Brother FAQ does not specify an “Accepted” message for this model, so do not rely on advice for another control panel.

If the warning remains after checking seating and the exact sequence once, use Brother support. Resetting again does not repair a drum, cartridge or sensor.

Worth avoiding

  • Do not buy another drum until you verify the first new drum was seated and reset correctly.
  • Do not use reset steps from a different model family.
