SOURCE: faded stripe down the printed page

I found a solution that worked to eliminate the faded black stripe down the page thanks to a post by slamfix in another forum. The problem is related to ink build up on the blade edge of the black developer assembly in the imaging unit (the imaging unit contains 4 separate developers - yellow, blue, magenta, and black). The solution involves taking out the imaging unit, removing and cleaning the blade edge of the black ink developer until smooth. It took me about 15 minutes to complete and was fairly straightforward.

SOURCE: Samsung CLX-2160, keep getting faded

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.

I ran a full clean and maintenance on mine and it worked fine for another month but then it started smudging and putting lines over he paper again. I ended up throwing it and buying a new printer as the Guy at the shop said its worn out. After 4 years of heavy duty printing, it wasnt a bad run.

Black streaks on paper while printing or copying on scx 4725fn


Locate and check the printer drum. You should be able to see the mark that is causing the line on your page. It could be s scratch or a ring of toner that the wiper is not picking up because a nick or something under it. Try cleaning the drum with a very soft dry cloth and inspect it again. If the mark is still there the drum will have to be replaced. Do Not Try To Clean The Drum With Any Type Of Solvent!

The printer prints thick lines in the work


Open the toner and see if there is no trace of ink attached to the drum (green cylinder). Try to clean the surface, if the damage or the results remain striped print, you should replace the toner.

Stripes on Images only - Text OK


Perhaps the CMY color heads need alignment. If you have not already done so, run a head alignment from the driver maintenance section. It will print out a page containing several lines and text, and request you select the closest-aligned images. After this is done, do another image print to check for improvements.
Normally, the printer uses the black cartridge for text and the CMY inks for images (even for black on photo and specialty paper). So when you are printing normal text pages on plain paper, only the black ink is used. A good check for this would be to print a normal text page, but select photo paper in the driver to trick the printer into using the CMY inks to make a substitute black text page. If this looks ok, then you are having issues other than cartridge alignment.

Clean the Feed Roller In the middle of the printer. Take the paper tray out- you will see the roller in the middle. Send a print job with paper tray removed. Press the black thing to fool the printer that it has paper. You will see the feed roller move. When it is in the position you want to clean- open the toner door and it will stop moving so you can clean it. Isopropyl alcohol and LINT FREE CLOG.
