Your scanner is defective. It is not worth fixing. Sorry If you send out a fax it will be black also.

Whenever i send a fax, the machine confirms by viewing 'TRANSMITTING OK' but the addressee receives a blank document


Check the baud rate of your transmissions. Slow them down to the slowest setting and send a test fax to a helpful person. Slowly increase the baud rate (communication data speed) and send the fax test. When the fax doesn't show up on the receive site, then step one baud rate speed back, and save the setting.

It could also be your fax that is faulty, or even the receive sites fax, also being faulty.

To test your copy-head, insert a document into your loading section of the fax and press copy. If the copy prints out fine, then you know the head is reading correctly.

It is also possible that the receiver fax (the other end) has a printhead failure.

When I send a fax the receivers copy is black.


Make a copy with the machine. If it comes out black as well your scanner has gone bad. In other words when you insert an original to be "scanned" so it can be faxed or copied, it is being read as all black. Usually this occurs because the row of led's that light up the original go bad. Now I have seen in some cases, if you unplug the machine for a bit then power back up the problem goes away so try that. Test by making a copy. If this does not work then your are looking at a scanner assembly replacement or just get a new machine.
Good Luck and Thank You for using Fixya.

My brother fax machine - only receives black pages


do a quick check on 2 things.
- Copy a document(put a printed page on document feeder and press Copy button) , has the Copy come ok? if copy is also blank that means toner/ink problem, needs to be replaced.

- check with your Fax receive Print settings. is any setting of econo mode/ contrast/brightness Off the track? If found any of such issue then Reset it or put it on average (middle).

Hope this will put your Brother on the track

How can we tell if our fax machine is working


basically if the fax is well kept, its dialing properties will remain ok. what you need to check is the quality of print out. to test the quality of print out just try to copy a sample document. if your fax is a thermal type, change the paper first before proceeding with copying. if your fax has a menu and help button try pressing the menu first before help for the fax to print a helplist.

Poor Quality


If you can copy ok you have effectively ruled out your machine as you have used both the scanning and printing mechanism of the machine.

It will probably be the fax on the other end as if it sends a poor quality page that's all your machine can receive, a poor line can also cause problems if it is from multiple faxes. If so have your provider check the line (you probably hear static on the line).
