The problem you are experiencing is a common problem with this printer. What happens is over time as the printer is used, toner or developer builds up a film on the developer blades. The developer blades meter the amount of toner that the printer puts on the paper to make the image. As the film builds up, less and less toner makes it to the page causing the image to become faint. The black developer blade probally is clogged.
This can be fixed two ways. The easiest and most expensive is to buy a new imaging unit for about $100+. The second is to disassemble your imaging unit and clean the developer blade(s). This can be done in about 30 minutes. I have posted instructions in my Tips section.
Spend a little time searching the topic on google and even this post. It appears that this has been a well documented problem since at least early 2008. The problem appears to be the imaging unit. According to several posts, Samsung has replaced several of the units. I purchased my CLP-300 in November 2008 and it worked with no problems until about 8 months in. The black text would print very lightly on the left side of the page about 1/4 of the way into the page. There was also a streak that ran down the page vertically that disrupted the text. I could change the font to any color and it would print just fine. After replacing several toner cartridges, I just began to print in a dark color for many months. After discovering all the posts on the internet this week, I contacted Samsung today with my documentation and evidence. They basically blew me off stating that I was outside of the 1 year warranty period and there was nothing they could do. I was even hung up on by a Samsung employee named Michael. Tonight I plan to take a hammer to it to relieve a little frustration. I cannot understand why Samsung chooses to ignore this well documented problem. Good luck.
check if your toner cartridge(s) is moving the toner supply spiral, you can see it in hole where toner leaving bottle. (you must push the valve in cylindrical output of cartridge inside about 20mm). When you rotate anti-clockwise gear of cartridge, the spiral inside must rotate too. My original toner has this broken and print was light.
You can have also bad developer unit, blade, or contacts, or printer electronic board.
If its brand new then it is dead on arrival. you may approach sales department.
if u want to troubleshoot u need to check installation of transfer belt. imaginb unit.
try testing page by pressing continuously cancel button onthe printer.
I had the problems with white smear type fading on one side of the page , when pritning black, but colour printing seems OK. Did everything suggested in the manual and more. Changed toner. Been working on it a week. (I got 2000 pages out of that thing).
Now I have the solution. Bin the Samsung and buy a Canon.
