The Brother HL-L2540DW printer "0B error" typically refers to an issue with the toner or drum unit, specifically indicating that the drum or toner is not properly installed or is malfunctioning. Here’s a step-by-step guide to troubleshoot and resolve the "0B error":
Steps to Fix the Brother HL-L2540DW 0B Error:
Turn Off the Printer:
Power off the printer by pressing the power button.
Open the Front Cover:
Open the front cover of the printer where the toner and drum unit are located.
Remove the Toner and Drum Unit:
Carefully remove the toner cartridge and drum unit together as one unit. Be cautious not to touch the drum’s surface, as it can be sensitive to light and fingerprints.
Check for Obstructions:
Inspect the inside of the printer for any paper jams or debris that might be blocking the toner or drum from seating correctly.
Reinstall the Toner and Drum:
Reinstall the toner and drum unit back into the printer, ensuring that they are properly aligned and seated in place.
Close the Front Cover:
Close the front cover securely.
Power On the Printer:
Turn the printer back on by pressing the power button.
Test the Printer:
Print a test page to see if the error persists.
Additional Troubleshooting:
If the "0B error" still appears after the steps above, it could indicate a deeper issue with the toner or drum. Here are some additional things to check:
Check the Drum and Toner:
If the drum or toner is old or damaged, it may need to be replaced. The "0B error" could signal that one of these components is faulty or near the end of its life cycle.
Reset the Drum Counter:
In some cases, the drum counter might need to be reset. Here's how to do it:
Turn off the printer.
Press and hold the "Go" button.
While holding the "Go" button, turn on the printer.
Continue holding the "Go" button until all the lights on the printer turn on (about 10 seconds).

Try a Different Toner or Drum Unit:
If you suspect the toner or drum is causing the error, try replacing them with a known good unit to see if that resolves the issue.
Contact Brother Support:
If you’ve tried the steps above and the error persists, it may be worth reaching out to Brother’s customer support for further assistance, as it could be a hardware-related issue.
