Question about Brother DCP-7040 Laser Printer

1 Answer

I have cleaned the drum unit and corona wire but get almost entirely black pages now. Will a new drum unit fix this or is the machine dead? Hate to put money into a new drum unit if that's not the fix.

SOURCE: Pls Clean Drum

The drum is the larger plastic unit that slides out an the toner cartridge fits into it. The corona wire is the very fine wire at the front top of the drum. Just slide the little cleaning tab back and forth.

This will solve most "Toner End Life" message problems when you know that there is toner still in the cartridge.
1. Remove the toner assembly by opening the top scanner lid, then pull(tilt) open the front panel, and pull out the toner assembly by gently grabbing the tabs and pull out with an upward motion. The toner cartridge(grey color) and the toner holder assembly (black color) will come out.
2. At the top rear of the assembly you will find a square green tab that can be slide along lengthwise of the toner. Just slide it back and forth fully several (5 to 10 times) times. I carefully blow on it as well(no spitting!) while sliding it.
3. Put the assembly back into the printer, Close the front cover, and drop the scanner cover.
4. Whala ! (usually), actually this has worked everytime for my brother and myself.

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.

Copies are black and where is this corona wire? I


Your cartridge has two sections, the drum and the toner section. The corona wire is on the drum section. There should be a blue tab on the top left hand side of your drum unit. Slide this tab across the cartridge one or two times, returning the tab to its original position. There should be an arrow on the blue tab that will match up with an arrow on the drum unit when the tab is in its resting position. Performing this action cleans the corona wire inside the cartridge. If this doesn't fix it you may need to purchase a new drum unit.
