Hello ,

This problem is a common issue and easily fixed.
When putting in a new toner cartridge, the printer usually automatically resets the toner count.
In a situation like this, the printer did not automatically do the reset and so we must manually reset the printer.

To manually reset the printer, first, remove the toner from the printer and separate it from the drum unit.

With the toner cartridge in hand and the brother writing facing you, look to the left side of the cartridge. You should see an arc shaped opening with a white tab in it.

The tab is set at the right position and must be pushed back to the left side of the opening.
To push the tab back, you must turn the grey gear attached to the front roller upwards as you push the tab.

Once the tab has been placed to the left position, the printer will accept it as a new toner cartridge.

Thanks,

Pat

To clear white vertical lines from printed documents follow the steps listed below:

NOTE: The use of non-Brother or generic toner may cause white vertical lines.

Brother strongly recommends that customers do not use generic drum units and/or toner cartridges, or refill their Brother toner cartridge. Each Brother laser printer is designed to work at pre-set temperatures that are matched exactly to each of our individual toner formulations. Each individual component is designed to work with the other to ensure quality and reliability. Using non-Brother supplies may affect the hardware performance, print quality and machine reliability.
The Brotherlimited warranty does not apply to any problem that is caused by the useof unauthorized third party drum units, toner cartridges or toner.

1. First, power OFF the unit for safety. The ON/OFF switch is located on the left, rear side of the unit.

2. Open the scanner cover by pulling the blue lever located below the control panel toward you and lifting the cover. Make sure the cover is completely open.

3. Remove the drum unit by holding each side of the drum by its handles and gently lifting the drum forward (toward) you.

4. Place the drum unit on a drop cloth or large piece of disposablepaper to avoid spilling and scattering the toner. Make sure thedirections and DR-250 stickers are facing you.

5. With the drum removed from the Brother machine, clean the laser glass. The laser glass is located inside the Brother machine where the drum was located. It is a piece of glass, about 1/2 inch wide and approximately 8 inches long, located on the bottom of the inside. Gently wipe the glass with a clean soft DRY cloth. DO NOT use isopropyl alcoholor any liquid to clean the glass.

6. Gently pull up on the mauve lever to turn the toner cartridge toward you until it stops. Remove the toner cartridge from the drum unit by gently sliding it out of the drum unit. ***Handle the toner cartridge carefully. If toner scatters on your hands or clothes, immediately wipe it off or wash it with cold water.

7. Gently rock the toner cartridge from side to side five or six times to distribute the toner evenly inside the cartridge. Then, reset the toner into the drum (be sure it clicks into place). Gently push on the mauve lever to turn the toner cartridge away from you until it stops.

8. With the DR-250 sticker facing you turn the drum upside down. There is a blue tab located on the right side. Slide the blue tab back and forth seven times to clean the corona wire. When finished, make sure the blue tab is locked to the right side of the drum.

9. Reset drum unit in Brother machine. Close the cover securely.

Print the help list to test the unit by pressing the REPORTS key located on the control panel and then (1) on the dial pad.

If the white vertical lines still continue, the drum unit will need to
be replaced.

If the purchase date of the original drum or replacement drum is less than 90 days (within the warranty of the drum), contact Brother Customer Service Center at 1-877-Brother (1-877-276-8437) . The center is open Monday-Friday, 9:00am to 7:00 pm EST, excluding holidays.

Leave it in. Turn printer off. Unplug it, all cables, replug it, turn it on and print something even if it doesnt print, now try and remove again.
