Tips for a great answer:
Sounds like a fusing error . If your able to wipe the toner off the page its a fuser unit problem (replace fuser unit).
Also clean the copier's paper rollers. Marks on copies will occasionally be the result of a dirty paper-rolling mechanism. Simply access these rollers (your photocopier will likely have a plaque or series of signs indicating the locations of these areas) and wipe them off.
Clean the copier bed's glass plate. One of the most common causes of blemishes in photocopies is a dirty glass plate. In some cases a permanent mark, such as a scratch, will be present on the plate, showing up in every copy as a dark line or spot. However, most problems attributed to the glass plate can be fixed by wiping the plate with a soft towel and common household glass cleaner.
Clear any excess toner that has spilled or overflowed in the toner cartridge chamber. Excess toner will almost always result in blemishes on your copies. The most effective means of cleanup is to remove the toner cartridge and set it aside, thoroughly cleaning up any spilled toner in the compartment before putting the cartridge back in place.
Check for low toner levels. Low toner levels can actually contribute to unsightly lines and blotches on a photocopy. Most photocopiers will automatically indicate the need to replace an empty or low toner cartridge; while the toner is low, these models will permit continued copying. Consult your photocopier's instruction manual or key to warning lights and indicators for how to tell if the toner is low or empty.

You have to determine if your FAX is the problem or the sending FAX has the problem. The first thing to do is make a copy or print a report. If it comes out clean you FAX is NOT the one with the problem. The sender has to get their optics cleaned.
On the other hand, if it's still "streaky" then your fax has a problem. First off remove the cartridge and look inside it, if you see toner get a can of compressed air (sold in office supply stores to clean keyboards) and blow out as much as you can. I suggest taking the machine outside the toner dust can make quit a mess. Make a few copies (5 - 10) to check it out. Each copy should come out with less misplaced toner.

Have you tried both drum and toner supplies? cause it sounds like a drum fault, if you have tried a new drum and toner, and it is doing it when printing internal reports, receiving fax's and copying then you have a tecnical issue to do with charge and this would likely render machine unecomical to repair (unless you can find a bad contact with drum on machine). If it receives faxs clearly but copys black then it is different issue (ie optics).
