Black streaks when coping

Why does our 2840 leave 1/3 of a section of the paper black and fades away on the other 2/3 rd's? It has done this since it was about 1 month old....

    I have the same print problem, 1/3 of the page prints and 2/3 of the page does not. I replaced the black cartridge, it ran through a self-clean mode and it is still there.

The carousel that the toners are in has probably slipped a tooth on one of the gears at the sides. Look at the toners while they are in place and check that they appear level and consistant when compared to another straight edge adjacent to them. The carousel timing will require adjustment if they are not level.

To perform a clean reset:

1) Press and hold the Calendar button, the Power button, and the Messaging button.

2) While holding these buttons, use the stylus to lightly press the Reset button on the bottom of the HP iPAQ.

3) When the Pocket PC screen begins to fade, release all of the buttons, and then remove the stylus from the Reset button.

The HP iPAQ restarts and powers on.

Make sure you hold the keys down long enough.

When we attempt to print it leaves black streak marks. At first it printed all black and when we went to setup under maintainence we chose alignment and clean cartridges. This worked however we still see...


If an inkjet printer gives white streaks where it should be black, it means the ink is very low, or there is dirt under the nozzles preventing it from printing properly, or, in the case of non original cartridges, ink might be leaking which prevents the bubbles of ink to squirt onto the page.

If the streaks are black where it should be white, is sounds like some dust or fluff below the cartridge leaves ink smears on the page.

Our copies are streaky like the drum is not clean.... help! There is black streaks on the top of all of our copies on our canon imagerunner 3300.


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.

I have fading on the right hand side. Printer Dell 3100CN


Dell printers are junk. But you have put a lot of money into this thing. Check the alignment of the black drum, could be that something is keeping if off track a little bit.

Black streaks on paper when printing message


That green bar is the drum unit. Black streaks are indication of bad drum. Replace drum unit. Don't wait too long or it will ruin the fusing section as well from excess toner build-up. Big bucks!
