After clearing a paper jam when you print the right side of the printed paper is not as dark as the rest of the page. I have replaced the fuser to no avail is there an adjustment that needs to be made?

Hi there! Wich color is not dark as the rest?Only when you print in black and white or even in the color printing? If the black or any of the colors are not dark as the rest of the page you must clean the led scanners(Wehn you open the top cover you will see long black boxes on the top cover,those are the led scanners) if they are clean then your transfer belt is damaged and can`t transfer the image from the drums to the paper.You can check the belt by starting a printing and open the top cover while the paper is moving under the toner cartridges and look at the page!Please replay what you have seen so i can help you futher!Thaky for usin Fixya.

I have replaced the toner cartridge on a Xerox XC 830 copier with several new cartridges. I still get light images and horizontal dark and light stripes where it should be a solid dark block.Drum was...

Have you attempted to print to the copier? Doing this completely bypasses the optics of the copier and therefore you are able to potentially narrow down the cause of the banding.

On cleaning optics: on the right hand side of the machine, near the top, or on the top, of the scan bed there should be two to four screws that hold a plastic cover in place. After removing the cover you should be able to gently lift the glass up and out of its housing. Using windex or any other sort of glass cleaner on the reflective mirrors will do the trick. However, this does not sound like an optics problem.

Have you inspected either the transfer belt, roller, or transfer corona wires? All of these parts can be accessed from the right side of the machine. Gently clean the thin wires with a rag and some sort of general cleaner.

Copies come out perfect on the top of the page but the image is fades to almost nothing at the bottom of the page. Adjusting light/dark settings either bleeds out the whole image or causes Shading. What...

Have you changed the paper or flipped the paper over yet? Have you gone to add. funcations and go to cleaning and run the wire cleaning. Also, I would clean and replace all of the corona wires.

My pages are printing correctly on the edges but light in the middle on my clx 3160fn. it has a new black ink cartridge

Is it only with one colour ? I had the same problem (only with black) and before buying another unit dismantled the imaging unit to find a build up of toner on the metering plate edge, I cleaned it and now it's fine.
It takes a bit to get to... 3 fixing screws each side plus one for the belt shute and one at the top. Remove the side plates, followed by the image drum (with great care) then each colour toner roller unit (they just slide forward) until the black unit is exposed. Remove the 5 cover fixings and then you can clean the plate edge. kh

Copier too dark

Did you clean the lens and the mirror under the lens cover? If so, There is a VR behind the front cover of most small Xerox machines. One VR makes the image darker/lighter and one VR changes the lead edge registration.

I have a dark line across copies

Whats the make and model of the copier?
One culprit might be the drum.  If you can take a look at the drum from your copier and you see black lines on it.  It could be scratches on the drum or it may need a new cleaning blade to clean the toner off the drum.

Cannon PC1061 making dark copies

OR you can do it yourself.

your problems seems to be Dirty Mirrors.

Your copiear has 6 mirrors that need to be clean up. 5 of them are kinda easy access. the other needs to be clean thru something thiner than your fingers. (you can see the mirror but no way you can reach it).

Now dont worry (not yet) about that 6th mirror since THEORICALLY it doesnt get dirty.

So try first to clean up the other mirrors. and see what happens.

They are located below the platen glass (remove it) and be careful with the lenses (do not touch them). clean everything that seems to reflect light Or images.

If nothing changes you may want to try out with a new cartdrige. Your drum may be done.

HP LaserJet 1012 Printer prints ghost images

I ran the hp toolbox "cleaning" mode too and it did not help the problem at all. I still have a dark smear concentrated in the middle of the page, and ghost images repeated lighter all the way down the page.
