The only other thing to do is to actually disassemble the drum unit, and "clean" it as a whole. If you are not a service tech, as I, then it's a sketchy thing to do, as it involves "re-dusting" the cleaning blade.
barring that... you may just have to simply replace the drum unit to correct the error.

We have a Brother mfc-9320cw printer that is printing with a thick and ugly crust of ink on the right edge of every 8.5x11" sheet we print. What is causing this? We've replaced the belt. It...


This happened to mine, only my thick edge was blue. My problem was that the little green slider that cleans the wire on the toner holder was pushed to the wrong side. (Sorry, can't remember technical term for the green thing or the wire! It has an arrow on it and it's pretty easy to spot.) Push it all the way back to the left until it clicks and it should fix the problem.

I am getting white specks on all four colors on my phaser 8500 and some black smudges. I just did a smudge clean and it helped, but it didn't clear it.


Hello.

Try a laser printer roller cleaner (paper sheets), like PathKleen or Perfect Data. You may need to run sheets through several times before the cleaning is complete. Do not use a sheet more than once.

Hope this helps.

Vertical Lines through incoming faxes and copies.


Sometimes you may see vertical streaks/black lines
on the faxes you receive. Either your FAX/MFC's
primary corona wire for printing may be dirty, or
the sending party's fax scanner may be dirty. Clean
your primary corona wire (see pages 13-18), or ask
the sender to make a copy to see if the problem is
with the sending machine.
Cleaning the Drum Unit
We recommend you place the drum unit on a drop cloth or large piece of
disposable paper to avoid spilling and scattering toner.
1 Carefully turn the drum unit upside down.
2 Clean the primary corona wire inside the drum unit by gently sliding the tab
from right to left several times.
3 Return the tab to the Home
position (  ) before
reinstalling the drum unit.

Says drum error, see troubleshooting maitainance chapter in user guide. Don't have a users guide. Printer is brother mfc-7340


I have this manual for you. I can be reached at LBrown18062@hotmail.com

http://welcome.solutions.brother.com/bsc/public/as/as_ot/en/doc/manual_index.html?reg=as&type2=-1&prod=mfc7340_us_as&c=as_ot&lang=en&flang=all

Drum Error - The corona wire on the drum unit needs to be cleaned.
Clean the corona wire on the drum unit. (See Cleaning the corona wire on page 122.)

Cleaning the corona wire: If you have print quality problems, clean the
corona wire as follows:
a. Turn off the machine's power switch.
Unplug the telephone line cord first, disconnect all cables, and then unplug
the power cord from the AC power outlet.
b. Open the front cover.
c. Slowly take out the drum unit and toner cartridge assembly.
CAUTION: We recommend that you place the drum unit and toner cartridge assembly on a clean, flat surface with a sheet of disposable paper or cloth underneath it in case you accidentally spill or scatter toner.
Handle the toner cartridge carefully. If toner scatters on your hands or clothes, wipe or wash it off with cold water at once.
To prevent damage to the machine caused by static electricity, DO NOT touch the electrodes shown in the illustration.
d. Clean the corona wire inside the drum unit by gently sliding the green tab from right to left and left to right several times.
CAUTION: Be sure to return the green tab to the home position (a) (1). If you do not, printed pages may have a vertical stripe.
e. Put the drum unit and toner cartridge assembly back in the machine.
f. Close the front cover.
g. Plug the machine's power cord back into the AC power outlet first, and then reconnect all cables and telephone line cord. Turn on the machine's power switch.

It is not making copies, the print is so lite you can not see them


Firstl, try cleaning the corona wies by pressing the 'head' key the head shape key with a star inside, select 'adjustment/cleaning' then select 'clean wires' then 'ok' Do this a few times to begin with. Your corona wires may need physical cleaning or replacement - there are several wires inside this machine - you can see 2 of them when you slide out Unit 2 of the machine, to the right centre of the machine. The others are behind the front cover above the drum. Are prints or internal reports ok - if so, then you will need to clean the optics (mirrors below the scanning glass plate and the glass sheet and slip glass to the right on both sides).

Good luck

Copying problem


Vertical lines on the copy usually indicate a dirty drum or Corona wire. The Corona wire should be cleaned each time you replace the toner cartridge. This is done by moving the Corona tab back and forth across the wire several times to clear it of debris. You may also want to check the drum for debris. Holding the copied page to where it feeds out and lining up the line or mark on the page will give you an idea as to where the dirt may be. Best of luck with your printing issue.

CORONA WIRE CLEANING


SWARNAVA has the most common wrong answer to this problem...

I am waiting for a firmware update to fix this issue. The only solution is repeatedly removing the drum/toner, moving the green cleaner back and forth, putting it all back together loosely, putting it in the printer loosely, and closing the door gently. Hold down the blue button until all the lights glow, then release. If you're lucky you only have to repeat this process a dozen times until you trick the sensor into not giving false readings.
