Black Toner Problem

Problem is that there is a white/blank stripe going down the left side of the page ONLY involving the black toner. In other words, if I print a page that is both black print and color images, just the black print is missing off the left side, color comes out fine on the left side. What is up with that???

    I should add that black toner is full/new cartridge. And black toner everywhere else on the page is fine.....

    I have the same problem - I have tried cleaning it and even put in a brand new blank ink - this did not help I still have a blank streak down the left side

    Exactly the same problem. This started before toner replacement and is still happening despite buying new genuine cartridge. Every other colour works fine. Stumped.

  • Anonymous Feb 06, 2008

    All else applies. The only difference is that I have similar streaks down the page, about 4, where the print is faded.

    1. Changed Black ink cartridge. Shook to ensure redistribution of toner. 2. Cleaned m/c (Took out imaging unit and inspected drum visually), 3. cleaned orifice where Black cartridge goes.

    Problem persists.

    I have the same streak down everything I print. Nothing seems to make it go away even replacing the items that Samsung tells you to.

    All toners are brand new and authentic Xerox products. Black and white is fine, but color pritings always have a very precise blue or purple strip down the page, slightly left of center.

I had the same problem with my 4 month old Samsung. All of a sudden i had a missing black stripe down the left hand side after replacing the cyan toner with a refilled one!! So.....i uninstalled all the old drivers and downloaded and installed the latest ones.... replaced the cyan with a new genuine toner....removed the black toner, shook to redistribute and put it back.....checked the imaging unit for actual visual damage (there wasnt any!)..... then printed off 50 or so black n white documents. Eventually the 'stripe' dissapeared.

The colour toners were fine all the way through!

It worked for me, hope this helps!

    Thought I'd fixed this problem, but it eventually came back! Had to change the Image Unit in the end....after less than 7000 images......not after the 20000 as it recommends in the manual!

You just might have a faulty black toner cartridge think back did the problem arise when you installed the new black cartridge. Also is the toner a original if not change for a original.

Hope this Helps
Thanks J

Run the 1/2 print test.
Put paper in the manual feed tray. Print a few pages of anything. As the paper gets about 3/4 of the way into the printer, open the cartridge door. Pull out the cartridge and look down at the paper. If it has the black stripe on the left side, replace the toner. In fact at this point, pick up the toner cartridge and gently swing the shutter open and look at the drum. You should be able to see a black stripe on it.

By the way, the toner hasn't been fused to the paper at this point. It will rub off on hands and clothes.
If the 1/2 test shows no stripe on the paper...replace the fuser.

Clean the Corona Wire carefully to remove any residue. As the charge on the wire is effectivley masked it cannot deposit any toner to the page and will result in a consistent white vertical stripe.

Samsung CLX-2160, keep getting faded toner stripe down page. changed toner numerousof times The same problem occurred for me after only 300 pages. The black color on the all prints is faded out on the...

Everyone will tell you that it's the Imaging Unit - happy to say that's not true. If it was the imaging unit the colors would not come out right either. I bet if you print a test page that all the colors come out fine across the page. It's only the black.

Also - if you replace the black toner cartridge, or reinstall your printer and drivers like some people will tell you - still no results.

The problem is in the black toner cartridge PATH inside the printer. Something has jammed it up a bit. Try taking out the black cartridge and blowing firmly into the small hole at the bottom of the spout that looks to have a sponge inside. Use a straw and make sure your air blown is dry. Then lightly tap the cartridge a few times. Then use the straw and once again blow very firmly inside the receiving path (inside the printer) for the spout on the cartridge. Make sure you are blowing into the spout path at the bottom - not the gear drive path in the middle - as that will not do any good.

Replace the cartridge, warm up and print another black and white page. You should see that the faded out section is gone or diminished in size. If it is not gone, simply repeat the above steps until it is gone. You will see that the faded out strip gets smaller and smaller each time until it's gone. I had to repeat five times, but eventually got it corrected. Now prints like brand new so don't get discouraged.

XEROX CopyCentre C20-Blank stripe going down side

Open the cover and put a piece of paper on only half the glass, and make a copy. BLOCK the left side of the glass with the blank paper.
See where it is blank. Most of the times that is a dirty or haved up mirror in the scan head. One of the small mirrors in the black assembly under the lamp. When a digital copier scanner optics become dirty, the image in that area becomes very light .

Blank stripes on page left to right

If the blank stripes go up and down the page (vertical) then it sounds like the laser lens has simply got toner on it. remove the toner and photo conductor units. Look for the glass panel that covers the laser lens and simply wipe it off with a cloth. Some machines incorporate a lens wiping pad that can clean the lens without taking out the parts. I can not remember if the 1710 does or not.
