Blank Streaks I've been receiving faxes with streaks down the page. Sometimes black streaks and other times blank steaks. I have changed toner cartridges and I'm still unable to read the fax.

Here is a great how to on Black Streaks issues with any printer.

A) Black Streaks, Shadows, And Ghosting
Adjust the printer's lightness/darkness setting to 2-3 different variables and see if problem disappears. Look at the fusing assembly - is the roller torn or does it have any black buildup? Use caution!!! It gets HOT!

Try another toner also.

Need to replace the fuser.

Hello sir; Either drum cleaning blade or drum cartridge needto replace.

I was going crazy! Had a tech come in and look at the machine - needless to say he did NOTHING! A friend came over and was trying different things. It was that the "rack" that the toner cartridges sit in was not fully seated - once he pushed down a little and heard it "click" I had no more black streaks. AMAZING

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

On top of the toner/drum cartridge there should be a blue slider, move back and forth 10 times.

If no fix, you need a new toner cartridge.

needs a new toner cartridge probably but the fuser rollers may be damaged as well usually if the lines are indented into the paper that means its the fuser roller if they just appear strait down the page then its the toner cartridge

The streaks are typically a sign of a toner drum going bad, or possibly just dirty, or even caused by the toner being low, as you have mentioned it to be. 1 way I know to 'clean' the drums is to have the printer run multiple blank pages. If your software will not allow you to print blank pages, type a single character by using this little trick, hold down the ALT key, and type 2 5 5 on the number pad in a blank text document. This will allow you to print the "blank" document, I would suggest about 10 copies. This should help for a short duration, and doesn't use any toner.

Hope this helps!

It sounds like the lamp/light is going out.  Open the top and try to make a copy and see if the light stays on the entire time.
