Document jam, printing is fine, but won,t copy or

Dear
I am a bit of confused about paper jam but you are able to print but facing difficulties in scanning. I think the document jam is there. Pl. check the ADF (automatic document feeder) a small piece of paper or any foreign mater may obstruct or jammed at the sensor. clearing this may help you.

Thanks.

Please can you tell me the model?

• Check the connection. The cord from the TEL.LINE jack to the wall jack should be no longer than
six feet.
• Make sure there are no modem devices sharing the same telephone line.
• Check with the other party to make sure their fax machine is functioning properly.
• Have your telephone line checked for line noise.
• Try connecting the fax machine to a different telephone line.
• If the problem still occurs, your fax machine may need service.
Clearing a jammed document
If the original document doesn't feed properly during transmission or copying,
or DOCUMENT JAMMED appears in the display, first try pressing start/memory . If
the document doesn't feed out, remove it as explained below.
Important:
Do not try to remove a jammed document without releasing it as explained
below. This may damage the feeder mechanism.

If a document jam occurs during a transmission, the message "DOCUMENT JAM" is displayed. If this occurs, follow the procedure below. It is recommended that a duplicate from a copier, of the jammed document be used to reduce the chance of a jam when resending the document.
See Chapter 3, "Loading Documents" for document specifications and recommendations which may help avoid paper jams.
Note: The power can be left ON when clearing a paper jam.
Typical Causes of Document Jams
Recommended Procedure
The document is fed at an angle.
Adjust the Document Guides to the edges of the
document.
The document paper is too thin or too thick.
Make a duplicate using a copier and use the copy
as the sending document.
Document has tape or pieces of paper taped to it.
Remove the tape or make a duplicate using a copier and use the copy as the sending document.
The Control Panel Cover is not fully closed.
Close the Control Panel Cover fully.
The document is stapled. Remove the staple(s), or make a duplicate using a copier and use the copy as the sending document.
Basic Troubleshooting
1. Remove all documents from the Document Support.
2. Open the Control Panel Cover.
3. Remove the document jam. Remove any pieces of paper, paper clips, or staples that may have caused the jam.
4. Close the Control Panel Cover.
5. Verify the display has returned to the Standby Mode.

I had the same problem with a Brother MFC-8460 and called Brother's support line. The solution that worked for me was to lift the top cover where the sheets of paper go through when you fax. On the right of the black rectangluar piece with grey roller there is a slot in the tray with a black lever inside. The black piece was stuck down inside the slot and had to be popped back out. Once it was out I hit the stop button and it was fixed!!

Please check rear door area for paper, can you use manual feed slot? Power off machine with all jams removed and paper loaded, then power on, can you tell us exact error message/lights that are shown in this state?

Does the fax machine produce a copy? If there is a paper jam/toner error, this needs to be sorted first. What is on the display?
