Frequently Asked Questions


What does it mean when the ‘Drum’ LED alternates turning on for 2 seconds and off for 3 seconds?

When the ‘Drum’ LED turns on for 2 seconds and off for 3 seconds alternately, it means the drum unit is near the end of its service life. We highly suggest you get a replacement drum unit soon.


What to do if the ‘Drum’ and ‘Error’ LEDs continue to blink even after clearing the corona wire?

First, check if there is no paper jam. If there’s none, it means the drum unit is nearing the end of its service. Get a new drum unit soon.


How come my Brother HL-2140 printer still shows blinking ‘Drum’ and ‘Error’ LEDs even after changing the drum unit?

When replacing a drum unit on a Brother HL-2140 printer, its page count must be reset once the new drum unit is installed. Try doing a manual reset by opening the front cover and holding the ‘GO’ button until all four LEDs are lit. Then, release the ‘GO’ button and close the front cover.
