Check the drum cylinder for a) a clot of fiber inside the corona wire channel; b) a groove worn into the surface of the coating. If those OK then check the fuser (inside at the back). Look for either a dirty fuser sleeve or a shiney track worn through the coating on the fuser. Dirty can be cleaned - shiney cannot be fixed

My Brother MFC-7420 Printer always prints black lines and splotches down the left side of my paper. This happens whether I'm scanning or printing from my PC. When I looked at my drum, it appears a


If you are seeing vertical streaks/black lines your primary corona wire is dirty and or the fax scanner may be dirty.
1)To clean the corona wire you take the drum unit and toner cartridge and place it on disposable paper to avoid spilling.
2) Clean the primary corona wire inside the drum unit by sliding the blue tab from right to left several times.
3) Return the blue tab and snap it into the home position.
4) Reinstall the drum unit and toner cartridge.
5) Close the front cover.
Caution: if you do not return the blue tab to the home position it may repeat the black lines.

Vertical single black line on printed pages - does this mean I need a new cartridge or a new drum? Brother HL 1250


The first thing I would try is to fix the corona wire. Here is a link to Brother's website outlining the process (clean corona wire).
What you need to do is pull out the drum and look for a blue tab on the top of the cartridge. Slide that tab back and forth along the wire and see if that clears things up.
I have had some luck cleaning the drum when I get black streaks but I have also hear this can be dangerous and make the problem worse.

4 streaks down the front of every page. Changed drum, changed toner, drum light is still blinking.


Did you try cleaning the corona wire or the glass?
Do it with a clean tissue dipped into alcohol.

A white piece of paper is printing out gray....think the toner is ok as the ink is black...something need to be cleaned?


Hello,

Two things can cause this type of problem, 1 bad drum unit or 2 dirty corona wire.

HTML clipboard Below are the directions to clean the wire.
1. Open the front cover and pull out the drum unit and toner cartridge assembly.
2. Clean the primary corona wire inside the drum unit by gently sliding the blue tab from right to left several times.
3. Return the blue tab and click it into the Home position.
4. Reinstall the drum unit and toner cartridge assembly in the MFC/Printer.
5. Close the front cover.

Be sure to return the sliding blue tab back to the home position next to the arrow or you will have dark streaks on your printouts.


If this does not solve the problem then you will need to replace the transfer drum in the printer. The part number for the drum is DR-400 or DR400.

I hope this helps, if so please rate our solution.

Print quality is poor. I hace cleaned corona wire and poblem is still there. Entire page is streaked with black. White paper comes out gray. What else can I do? Should I change the toner cartridge?


If you have a old drum or old toner cartridge switch them and see if it goes away. Other wise start with a new toner cartridge. I sell them for 40.00 and the drum for 60.00. Steven 818-888-0006

BIG BLACK STREAK ON PAPER


If you're experiencing horizontal streaks, and already tried changing cartridges but that don't help, look in the bottom of the paper tray. If that small metal ground terminal gets ditry or bent, that could be the cause.

I'm sorry to tell you, this is likely a drum issue.

You probably need to have a certified engineer examine the machine.

Have you tried speaking with the local service center to see if they have experienced similar issues? It might be free information.
