Re: cover open

The control panel opens to give you access to the scan glass and orginal feed rollers. There are clips either side which keep the cover down with time they can become weak and not hold down the cover correctly. While the control panel cover (top cover) is open carefully bend the clips outwards a little for more pressure. Also these type of machine can also read cover open messages when there is a jam inside. Check for jams including in the drum unit.

I have a brother 770 fax. When making copies or sending faxes the paper has long black narrow lines running from the top to bottom. Please help.

Hi There!
One reason why you're having a black line on the copies you make and faxes that you send it's because the scanner glass inside the fax machine is dirty. Here's what you can do to resolve you're issue.
-Make sure the printer is off and unplugged from the power outlet for your safety. -Open the control panel, Prepare a dry lint free cloth and isopropyl alcohol, dampen the cloth with a small amount of alcohol. -Inside the fax machine look for a the long scanner glass clean it with the dampened cloth, using hand try to feel if there are debris or dirt and concentrate on cleaning that part. -Directly above the glass you will see a white strip clean that also with the dampened cloth
Once you're done cleaning, close the cover and plug it back in. Try to copy a blank sheet of paper and if you can still see the same line clean it again for about 3-5 times, Make sure to make a copy everytime you clean the glass.
Hope this helps!

We have the Brother Intellifax 4100E. It was working fine up until last week. Then it started not receiving faxes. We can copy, and send faxes, and receive the confirmation. I have checked the mode button...

Try calling the fax machine from your mobile and see if it picks up or if anything shows up on the screen of the fax machine. Is it possible that you have plugged the fax machine into the wrong telephone line? Try sending a fax to your mobile phone and see that the number is correct.

How do you load a new ink cartridge?

Replacing the Print Cartridge
1 Open the front cover, and then open the top cover by pressing the blue levers on both sides of the top cover.
2 Remove the old print cartridge containing the used ribbon and dispose of it.
3 Remove the plastic stopper from the new print cartridge.
Note You can reuse the print cartridge until it breaks. If you purchased refill ribbons, follow the instructions that came with them.
4 Turn the black spool on the right clockwise to tighten the ribbon as shown.
5 Install the new print cartridge by inserting the recessed first, and then placing
the cartridge into its four holders.
6 Press down on both sides of the top cover to close it securely.
7 Close the front cover.

Vertical Black Lines When Receiving
The sender's scanner may be dirty. Ask the sender to make a copy to see if the
problem is with the sending machine. Try receiving from another fax machine.

You can save money by purchasing the 2-PK Refill Ribbon Rolls (PC302RF).

carefully, you can reuse it until it breaks.

When I send a fax, the recipients report a black band appears covering 3/4" in one margin

Open the front cover and clean the scanner glass - there must be some alien substance like dried up correction fluid or ink on it that causing lines to appear on the recieving side.

Where is the top cover switch? I can't find it.


This is the manufacter's official manual link:

On page 63 it shows you how to open the top cover. You must open the front cover first then open the top cover by pressing the blue levers on both sides of the top cover.

It also has a diagram.

Hope this helps!

Can't send faxes , keeps saying document jamed

Open the front cover by pulling it towards you (that is the cover where are the digits and other function keys), see if any paper has inside and than close the front cover and press the " Stop " button.
Remember if you do not close the front cover good the message will still appear on the screen because the machine thinks that the cover is not closed. That happen because of the sensor on the front cover which detects do the front cover is closed so check dose the door is good closed. If your machine do not pull the documents in the " document feeder " than open the front cover and you will see pair of rubbers inside, clean them with alcohol or glass cleaner and clean peace of cloth.

The tab is probably broken that trips the top cover switch. Try sticking a small piece of paper down where the tab used to go.
