Brother 4750e outgoing faxes are getting a black line down the right side. Incoming faxes are fine

If the stripe is a thin line, the scanner glass is dirty, if it is wide stripe you have a bad scanner block. EXPENSIVE

try installing a line filter

lift the auto feeder and clean the scanner glass that your pages scan across -it is dirty. You can make a copy afterward and this will tell you if you have solved the problem.

Move the blue slider on the drum cartridge side to side 10 times.

just copy a paper if copy is black ur scanner is dirty or dead .first clean scanner with tissue other wise change it.if copy is ok result not black that is due to telephone line.by mian jee

Your scanner block has a loose connection or it is bad.

1- itis on the Scanning unit open and look for a thin strip of glass, clean
2-the scanning unit is bad

Assuming it's only on Outgoing Fxs and not incoming as well ( that would indicate the drum)

1- check the small stip of glass and see if it has toner,
check the maintenance section of the manual (it's free, just register)

This problem could be Phone line problem, or hardware failure or receiver's (the machine of the person whom you are sending the fax) machine problem and so on. First, let's check the line, if you have another Phone line, please dial from the number to your number, also, connect the currently connected line to a receiver and call a Land-line number, if the outgoing or incoming is ok, the proceed forward, otherwise, you telephone operator should check the line.


Sometimes, sending fax to a particular number doesn't work, to make sure, try sending a fax to another number.

If the line which is connected to the machine is extended from another machine such as Receiver, Switch, etc... unplug them and connect the fax machine directly to the Line.

It's also important to adjust the compatibility mode, to do this, follow the steps below:

• Press Menu.
• Press the up or down arrow key to select Fax.
• Press OK.
• Press the up or down arrow key to select Miscellaneous.
• Press OK.
• Press the up or down arrow key to select Compatibility.
• Press the left or right arrow key to select Basic (for VoIP).
• Press OK.
• Press Stop/Exit.

If you place the scanning document/file on the auto-sheet feeder, you can help it pulling inside the passage or you can use the glass (flatbed) instead. Sometimes, this small mistakes with the sheet-feeder creates this problem. You can also clean the rollers inside the ADF (auto document feeder) passage.

If all of the above measure don't help, I would suggest you to call brother and seek their help. The rest is with mechanical or we can say hardware or firmware related issue. (use this form to contact Brother)

I wish you good luck.

The drum is scratch ,or there is a paper jammed .
