Re: thick black streaks on pages coming through the fax
Remove the toner cartridge and you should be able to see the matching black streaks on it, if it is the problem .....don't bother trying to clean it , it is supposed to be self cleaning and you can't improve this look...replace

The received fax is clean but when you send one out it has a black streak on it. Cool! So far so good. Makes sense because for sending, the fax scans the original document and parts of the scanning area could be dirty and so on. Therefore a black streak may appear. The same black streak would also appear when you make a copy, because the original document must also be scanned. Logical!
However for receiving faxes, the machine uses the internal memory and the print engine only, and the same applies to printing the transaction report, which comes from inside via the print engine. The scanner has no rol in either situation.
Clean the corona wire on your drum unit. It should be a blue tab on the top of the cartridge that you can slide from side to side. Make sure that the blue tab returns to the starting position (there should be an arrow on the tab that will match up with an arrow on the drum unit). If this doesn't work, replacing the drum unit should fix it. Drum units are only meant to last ~4 toner section replacements.
Where the original page that you wish scanned/faxed there will be a device called a "scan part". This device "reads" the paper to be faxed/scanned as it passes. It usually is found very near where the paper to be faxed goes in. If there is a spec of debris on this part it will cause a fine line straight down the document. If its dirty, the document will be too! Just give it a good cleaning and you should be fine. Did this help? Click "FixYa" below! Thanks Len
Problem is ambiguious but print out a report from your machine and if it comes out black, it is likey a toner cartridge problem. But if its OK make sure your scanner lamp comes on when reading the original
Yes it does, the rubber blade that cleans the drum is not doing its thing properly, hence leaving your mark, pull the drum unit out and expose drum by pulling back the cover underneath it, you should see your mark on the drum, don't touch drum with fingers or brush/clean it, it is photosensitive too so keep away from light for any period of time.
