Black strip in documents when I send a fax

If you lift up the top, like you are clearing a jammed original, you should see a piece of glass across the machine. Look for something on the glass, usually white-out, and clean it. Test by making a copy. If copy is ok, then you fixed the problem.

I have an intellifax 4100. I can send out faxes but I can't receive any. It's not giving me any sign that someone is sending me a fax.


Typically, the problem is caused by a faulty phone line (even though you can make calls and send FAXes). Contact your telephone/telecom provider for their assistance.
Hope this helps.

We can send faxes but we can not receive faxes. The fax machine that sends the fax tell it that our line is busy. Is that a machine problem or a phone line problem?

Problem lies in your Receive Mode setting. If you don't have a dedicated phone line for the fax machine, you need to set it up for either Manual where you answer every call or Fax/Tel whereby the Fax machine determines if the incoming call is a fax or phone call. Instructions per Intellifax 4100 Manual.

Select a Receive Mode
Choose the mode that best suits your needs by pressing the Mode button
repeatedly until the FAX and FAX/TEL lights show the setting you want to use.
You must answer every call yourself.
The Brother machine must be started manually
to receive faxes.
For use with a dedicated fax line.
Every call is answered as a fax.
For receiving fax and voice calls on one line.
The FAX answers every call and receives a fax or
double rings for you to pick up a voice call.
For use with an answering device.
The TAD answers every call and stores voice messages.
Fax messages are printed.

Gears grinding with Brother Intellifax 4100

Does it only make the noise when printing. Do you hear the noise when sending out faxes? I have heard grinding noises onlt when using poor quality toner refills, or the fuser gear and or drive gear asm is stripped. First try a known good OEM toner.
