How to Change a Toner Cart in a Brother HL 2040
By Brad Maddy
The Brother HL 2040 laser printer has a toner cartridge that supplies toner to the drum assembly so that the printer can print properly. When the LED on the front of the printer indicates you are low on toner, you will need to replace the toner cartridge to maintain good print quality. Fortunately, the toner cartridge can be replaced without any special tools.
Grasp the front cover of the printer and pull it toward you to open the toner door. Reach into the printer and grab the combined toner cartridge/drum assembly. Lift up slightly and pull it out of the front of the printer.
Place the cartridge and drum on a paper towel, spare sheet of paper, rag or other surface that can get dirty. Loose toner particles may spill from the cartridge.
Press the blue locking lever on the cartridge/drum unit to unlock the toner cartridge from the drum. Lift the toner cartridge up and away from the drum unit. Dispose of the old toner cartridge in accordance with your local regulations. Seal it in a plastic bag to keep loose toner from spilling.
Gently shake your new toner cartridge back and forth a few times to distribute the toner evenly across the width of the cartridge. Remove the plastic protective cover from the bottom of the cartridge.
Place the new toner cartridge onto the drum unit and press it down gently until it locks into place. The blue locking lever will automatically click into place. Verify that the toner cartridge is securely connected to the drum.
Locate the corona wire cleaner tab at the front of the drum unit. Slide it back and forth several times to improve the print quality of the drum. Set the tab back in the home position when finished.
Slide the combined toner cartridge/drum unit back into the printer and close the front cover.
