Black line down the right hand side of prints

Brother MFC-6800 USB (its a Laser)
glass is clean.
toner is relatively new (its full anyway)
There is a dark line about 1/2 cm down the right hand edge of the pages I print or copy anything. There are also dark horrizontal areas though they are fading. Drum built up static? The printer had sat for a time, unused.

B&w 6800 lots of horizontal black line areas. also, a vertical white strip about 3/4 inch wide about 3 inches from left side of paper


Hi!

the best thing is to make a copy using the glass and not the document feeder!If there is no lines on the copy simply lift up the cover and on the left side of the glass will be a thin strip of glass,Clean it with a dampened cloth and all line and marks should be gone1

Good Luck!

Improper printing


It sounds like you may need to clean your printer scanner glass. It may have white out ,etc. on it. There are two glass areas, one large and one small. Clean both and should solve your problem.

Lines on Paper


Under the drum there is a thin ****-glass. Make sure there is nothing on the glass. Do not use compressed air to remove the debris from the glass. Use a dust cloth or such. Using air will blow the debris into the laser unit and it will have to be taken apart to be cleaned.

Black line


The problem could be the system and not the printer itself. Try turning it off, unplugging and then replugging and switch on try again. Sometimes this can reset errors. Post back if no go lilacgerry xxx

Print quality bad


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.
