Samsung CLP-310 Colour laser doesn't print properly

SOURCE: Samsung CLP-315

try to do this set of instruction & solution:

1. Go to Start | Control Panel | Printers And Other Hardware | Printers And Faxes. Double-click the icon for your printer to open the Documents window and clear any pending print jobs by selecting Cancel All Documents from the Printer drop-down menu
2. Try printing a test page from the printer, not from Windows XP. Most printers have a built-in test function that's activated by holding down one or more buttons while the printer is starting up. Check your printer's user manual for instructions. If this page prints successfully, you know the problem is either with your connection or with the software in your computer.
3. Check your printer's USB or parallel connection.
4. Try printing something simple from Windows' Notepad. To open Notepad, go to Start | All Programs | Accessories | Notepad, type a few lines of text in a document, and try printing it. If it successfully prints, the problem is with the software program you originally tried to print from.
5. Try printing using Windows XP's generic printer driver. Open and run the Add Printer Wizard. When you get to the Install Printer Software screen, select Generic under Manufacturer and Generic/Text Only under Printers (see Figure 2).
   
6. Select No for Do You Want To Use This Printer As The Default Printer? (see Figure 3). Click Next.
   
7. When prompted on the next screen, tell Windows XP to print a test page. If the page successfully prints, then you probably have a problem with your installed printer driver. Either update or reinstall the driver.

SOURCE: Hi. My Samsung CLP 300 Laser is playing up. It

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.

If it jams every page, it is the infamous Samsung design flaw. There are dozens of reports of this problem all over the internet. The best solution: sell it or otherwise get rid of it ASAP and buy another type or model of printer. The 2nd best solution: call trained technician and ask to replace the broken part. It could be thermistor near fuser, some people say it is a photo-interrupter.
