When you go to print, your printer driver should have quality options. Make sure you're not using "economy" or "draft" mode. Try "quality" mode.

You do not say what exact model of printer you are using so any answer will be generic rather than specific.

Poor colour and black tone can be as a result of various factors:
1. Poor paper quality that you are printing on.
2. Poor ink or toner quality being used.
3. Use of Ink / Toner saving modes or software.
4. Worn or damaged printer components such as the fuser roll on a laser printer and other similar consumables with a limited page use life.
5. Poor quality content being printed, i.e. low quality images being printed at too high a print resolution.

It looks like you may have some damage to the black IU. If you have an old one or a spare to try as a test that might help. The drum is easily scratched and this then produces marks or lines in the appropriate colour.

I am a computer dealer in Perth and had to replace 5 of these printers out of my pocket. There is no fix and Samsung was very unfair and refused to replace these shoddy printers. Colour printed fine but black is faded.
It makes no difference if original toners or compatible ones are in use.
Samsung is very unprofessional in refusing to replace these printers with an inherent design fault.

You probably running out of black ink. Try replacing with new black ink cartridge.

Try to run a test print.

fist of all reunisall your printer driver ....
if problem dose not fix .
it means black colour laser section have problem so you can clean lens of laser if posible and replace laser secaner.


thanks

If you the image is faded and your toner supply is good, the problem is the developer blades in the imaging unit. During the normal use of the printer, there is a buildup of toner that sticks on the developer blade. The developer blade meters the amount of toner that gets to the drum that ultimately makes it to the paper. As the toner buildup increases on the blade, less and less toner that gets to the drum cause the image to fade.

To fix this problem you will need to disassemble the imaging unit and clean the blades or buy a new imaging unit. I have clean my blades and I don't have 20000 images it is about 7000 and I have a document to show you if you are handy.

Click on Knowledge base from this site , then in the search box enter poor black quality. Look under black is faded or missing

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
