What does communication error 20 06 mean on my

CRC error in answerback. It means the error correction digits didn't match the data that was sent. I've seen a few cases where this was bad phone line conditions - once I could see the phone lines scraping against the gutters in the storm outside the window - but usually it's a flaky Main Board in the fax.
Unplugging all the cables on the board and plugging them back in might clean a bad connection, but we're seldom that lucky.

Error code 71

That is a laser alignment issue...
You might get lucky:

1. unplug printer power cord from wall or powerstrip.
2. Turn ON printer (without the powercord plugged in).
3. Plug in powercord and turn ON printer again.

If error code 71 remains .... repeat above steps.... but I would advise replacing ($180 ~ $240) instead of repairing ($150)...

Hope this helps!

Right side of printed page is faded

pull out your drum unit and look inside machine above where the drum would be. you should see a black assembly that runs left to right with a "****" glass. may need a flashlight. clean that glass off with a clean rag. sometimes toner "scatter" will get on glass and cause this.

let us know,

Faxing is clean, streaks occur when copying

Open the document feeder cover. The scanner glass is dirty or you have a bad scanner block.

NG Codes poor line quality

To check your line quality is very simple. Unplug the fax from the telephone line and substitute it with a normal single line telephone. Make an incoming and outgoing call. if you hear any echo or crackle on the line when you are being quiet, then you have a noisy line and you should report it to your telephone company to have the line cleaned. If it is quiet then the problem lays with the fax. There are ways around the problem in the software of the machine but its quite complicated and best left to a trained brother engineer.

We can send faxes but we can not receive faxes.

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.

How do I fix my fax machine so that it does it's job. By that I mean how can I make it print and fax?

First .is the machine in an error state on the display? 2nd. You MUST use the line lead and adaptor that the machine came with for the tel line. Others just wont work and you may get a dial tone but it wont receive as it wont detect ringing current. As for not printing, does it make any sounds when you send it a print job or print a report from the keypad? Did it work with its previous owner? To reset the unit you have to enter the following on the keypad within 3 seconds to get it into the maintenance mode. Press *2864* that's star2864star. When it says "Maintenance" then enter 01, it will then go back to maintenance. Now press 55 to reset the scanner. When back in maintenance again the press 02, when back in maintenance again press 99 to exit it. All should work now and it will be as it was when it came out of its box. If this does not work then it has a circuit board fault and wont be worth repairing. Its a very very good machine. As an ex brother engineer I can say it was their best machine.

How do I remove a paper jam? The paper is

The following is general advice that applies to removing paper jams in most printers, copiers, etc.

Switch off the printer at the wall and unplug it. Remove the paper tray from the printer. Check to see if the printer has an access door in the rear to allow you to see inside (open it). Open any other external flaps (eg. manual paper feed tray) that will allow you to see inside. Open any internal flaps or levers designed for user operation and usually indicated with a green or orange coloured tab.

Always remove jammed paper by pulling it in the direction of normal travel only. Don't try to pull it out against the direction that it entered the printer. Sometimes rollers inside the machine have a knob (usually coloured green or orange) that can be used to manually wind the page through the printer or fax. Always turn in direction of arrow indicated only.

After removing page, return all levers, flaps, doors, paper trays etc to original positions, reconnect power to the printer and test

Output coming out the back

Hi Christi_Matt !!
the brother 4100 does not have any settings for that, all you have to do is to close the rear cover just move the machine arrown and you will notice that the cover is in the up position, make sure you move it down (lock it down) and as simple as that all your faxes should go to the front.
any other questions let me know.
just use my fixya ID at yahoo.... you know the rest
thank you.
