Brother TN2025 HL-2040 and FAX2820 – Reset toner low signal after the cartridge has been replaced

Brother HL-2040: If the low toner indicator fails to reset even though the cartridge has been replaced…

• Open the front cover and leave open while completing the following steps:
• Turn the printer off and hold the ‘go’ button while turning the printer on.
• Release the ‘go’ button after the three lights are lit.
•  Press the ‘go’ button twice.
• Once the lights are on solid, press the ‘go’ button five more times.
• The toner light should be off.
• The paper light should be on.
•  Close cover.
• The ready light should be the only light on.

Brother FAX-2820: Open the front door, press “options”, then “start”, then “1”, and then “0”. The screen should now show “accepted”.

If the machine still indicates toner low with a full cartridge: Take the toner cartridge out of the drum unit that it sits in. On the left side you’ll see a half circled groove with a tab inside it. If the tab is turned to the right (3 o’clock position) then it needs to be switched to the left (10 o’clock position) in order to trigger a reset when inserted into the printer.

You should be able to reset the toner count on other machines that use the same toner: DCP-7010, HL-2070N, MFC-7340, MFC-7420, MFC-7820N, DCP7010, HL2070N, MFC7340, MFC7420, MFC7820N.
