This is a manufacturing defect. Call Samsung at 1-866-726-4249 and explain the problem. They will replace your imaging unit free although you will most likely need to provide a credit card for them to hold until they receive the defective unit back from you.

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.

Here is my solution, hope it will solve your problem.
From your post, I believe your CLP-350N printer has enough black toner. The black cartridge is on the far right side of the printer, so the black toner is harder to go to left side of the roller than right side. Everytime we start the printer, it will move some toner of each color to the roller before it shows ready to print.
Because we always use B&W printing when we start the printer, but less Color printing. The result is there are always enough toner on the 3 color rollers, but the black toner is lean on the black roller. When this gets worse, the left side of the black roller may hardly get any toner at all -- so it only print black on the right side fo paper.
Step by step solution
(CAUTION: Never loss balance while tilting printer! You may drop and damage your printer! Hold the printer firmly all the time! Ask someone to help you if needed!)
Here, front of the printer is where you can access the cartridge, back of the printer is where you connect the power cord and USB cable, left is your left, right is your right.
1.Lift the front to keep the printer tilt to its back at about 45 degree
2.Power on printer while it's tilted back, wait untill green light is on
3.Open the front door, red light will be on, then close the door, printer will start up again,wait untill green light is on
4.Repeat step 3 once again, then put the printer back to level position
5.Lift the right to keep the printer tilt to its left at about 45 degree
6.Open the front door, red light will be on, then close the door, printer will start up again, wait untill green light is on
7.Repeat step 6 once again, then put the printer back to level position
8.Print some test page to see if there is any improvement of black print quality.(Hold the printer button for 3-5 seconds, it will print the test page.)
You may try several times and print several pages each time before you finally cure the problem.
Good luck! And do it safely!
