Question about Brother IntelliFAX 2800 Laser Fax

1 Answer

I have about 1/4" inch white line through the fax

I have about 1/4" blank line down the copy or incoming fax printed page. I replaced the drum (kept orig toner cart in) and cleaned the heating roller. I tried printing and in the middle of the print I opened the cover. The white line happens while the paper is coming out of the drum before it hits the heating roller. I'm wondering if its an electronic problem at this point. I appreciate any help. thanks, Fred

Hi Fred,

95% sure this is a thing called the corotron wire. Now, in working for Xerox on the helpdesk I could talk you through the fix but for this machine I don't know, so I'll leave it to you to decide if you want to tackle it.

1. Turn off the power and pull the plug.
2. Take out the drum again.
3. if the toner is in the way take it out too.
4. Ok, the corotron wire is in one of two places. It's either part of the drum or in the machine next to where the drum sat. The wire would have run the lenght of the drum sitting a few mm from the drum face. It's job is to deliver a high voltage electrical charge ( HENCE TURNING OFF THE POWER) to the drum which attracts the toner, and so forth..
The wire is about a hairs width and should be surrounded by a guard of plastic or metal..

Ok, if you can't find it then stop here and get a tech in to look at it..

If you can see it and get easy access to it then get a piece of gauze,tissue, cotton bud type of thing and gently run it along the lenght of the wire. If I'm right you should get a load of toner rubbed off..

If you could find the wire and it's broken then you need a tech to replace it.

4. OK, put it all back together again, let the machine warm up and try a copy of a good quality, clear original. Preferably something with a large body of txt that would show up the fault..

How's that work for ya?

When I receive a fax, it prints out perfectly. When I make a copy or scan to fax/email, the page has multiple black lines running down the length of the page. I have recently replaced the drum and the...


As the fax receives and prints incoming faxes ok then the print engine is working ok. the fact that the problem arises when copying or scanning indicates the problem is with the scanner or software that controls the scanner.
First clean both scanner glasses and the white area (white reference) under the doc feeder. When you are happy all is clean, follow the following instructions:
Press menu, * 2864 within 3 seconds. the display will show "Maintenance"
now press 55. The scanner will initialise and go back to "Maintenance"
now press 99 and the machine will go back to the default screen showing date and time.
Now do a copy. if you still have the lines or its all black then you will need a new contact image sensor. If all is well then that was a good cheap repair.

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.

Brother MFC 8220 all-in-one fax prints with a vertical line


First guess is you have a bit of dirt (often white-out from people scanning corrected paper that's not quite dry) stuck on the fax scan window. This should be described pretty well in your user manual (which you can download online from brother.com).

Its also possible that there is dirt (typically loose toner) on the laser scan window (there's a laser that shines through it to get the image pattern on the drum). That window is often along the bottom of the unit under the drum/cartridge (take the cartridge out and look). The Brother manual I've seen seems to ignore this possibility.

Print streaks DO NOT mean cartridge drum replacement in many cases !! On brother Intellifax or MFC or other laser copier/printer/fax, keep in mind that either the fax/copy scan window OR the laser scan window can get dirty. If the fax scan window is dirty, you see streaks on outgoing faxes and copies (but NOT incoming faxes). If the laser scan window is dirty, you see streaks on all prints (copies, faxes, print-from-computer).

Note also that when transporting/moving some laser copier with the toner cartridge inside, the toner can get out and make a big mess inside (including getting the laser scan window dirty). An air compressor can be usefull to blow it out. And sometimes using alcohol to clean is a BAD idea (maybe incompatible with plastic and rubber parts). A damp rag is probably fine.

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.

3-INCH WIDE VERTICAL LINES RUND DOWN LEFT SIDE OF FAX MACHINE


Do your incoming faxes have the same marks?
If not you might find that the scanning part of your machine has a dirty mark on the glass or that the unit has become faulty.
Try and take a copy from the machine and print from a report or any print from memory.
If you have the black lines on both then i'd suggest getting a new drum unit, if u have it only on the copy I would have a look at your scanner glass and see if there is a dirty mark on it. if not maybe call out an engineer as the scanner unit maybe faulty.
Need anymore help msg me.

Vertical lines


1st print a report, can you see the lines? Then either the drum is faulty or the laser scanner is. If the lines are not present when printing a report, make a copy and see then if the lines appear. If so, the scanner is faulty. Try cleaning the glass with glass cleaner. However, blank lines mean that bits are missing from the scanner itself and the scanner will need to be replaced.

Line down center of page.


Hi Sherrey, I think I can help! If you open the ADF cover where you insert your pages to make a copy. You will see a scanner glass about 1/2 inch wide and runs across the width of the printer. You can take a soft towel and some glass cleaner and clean the glass. There will probably be some white build up that looks like white out on the glass just make sure you clean it very well. I hope this helps!!!!
