The following can cause bands (vertical on a normal page)
Faulty Toner cartridge
Faulty Drum Unit
Faulty Transfer Belt
Damaged or dirty LSU glass
I've also seen this sort of thing caused by a crusty build-up of toner on a wiiper blade on the Transfer Belt, and or Drum.

If your printer looks like this:
Then you need to clean the developer blades. In the image above it is the black blade that need to be cleaned. If there are streaking on any other color, then they also needs to be cleaned.
To clean the developer blades, look to this link. http://losingambition.com/clp300imagefix/ It describes how to clean them. It only takes a few minutes to do once you get the developers out of the unit. Just be careful when you clean the edge of the blades. You need to make sure that the residue is completely removed from the edge. Also be sure that when you reinstall the blade that the little foam does not get trapped below the blade. Otherwise when you print the side where the blade is not properly installed will have too much color.
If you are afraid of messing your printer up, then you need to buy a new imaging unit. They go around $100.

hi im josh try this:
Understanding Potential Problems
Printers are mechanical devices with lots of moving parts. And any time you have moving parts, you have something that can break or wear out over time.
So when you click the old print button and nothing happens, what are the likely causes?
First, you might have the wrong printer driver installed in Windows. You might have either simply selected the wrong driver for your printer, or Windows might have mistaken your printer for another model, or the driver selected might be out of date. While we're in this area, it's also possible that various aspects of your printer setup might be incorrect, which can cause some highly unusual problems. You should also check your font setup because fonts themselves can cause perplexing problems if they're not installed correctly.
In addition, any new input or output device you've installed since you installed your main printer could have changed your printer's settings. (It's kind of like the last device installed gets dibs on key system settings.) If you've recently added a scanner or a digital camera or fax software or anything like that and then experienced printer problems, try uninstalling your printer (and all printer drivers) and then reinstalling your printer so that your printer is now the last device installed—and thus controls key system settings.
It's also possible that if you're printing large or graphically complex documents, you might not have enough disk space or memory to print. Make sure that you have plenty of both, because Windows needs all the space it can get to complete the printing operation.
Finally, you could have real printer hardware problems. These problems range from the mundane (you're out of paper, you forgot to turn on the printer, a cable came loose) to the fairly serious (your printer is broken!). Check all your cables and connections and make sure that your printer is actually turned on.
The bottom line is there are a lot of things you need to check if you have printer problems, both hardware- and software-related. So if you have printing problems, hunker down and plow through the problems/solutions section, coming up next.
One of the best ways to track down a printing-related problem is to use the Windows Print Troubleshooter, found in the Help utility.
Problem: Your Printer Prints, but Output Is Smudged or Garbled If your printout is not as you expected, there might be several causes. The most likely cause, believe it or not, is our old friend the poorly connected cable. If all the instructions don't make it from the computer to the printer, your printout will be incomplete, if not totally out of whack. Check all cable connections to ensure a good throughput of data. If that doesn't fix the problem, just change the printer cable. An old or damaged cable could be causing your problems.
Printing the printer's self-test page is also a good way to determine whether the problem is in the printer or in the computer—or somewhere in-between.
Another cause of print garbage might be the printer itself. If you have a low or old toner cartridge in a laser printer or a near-empty ink cartridge in an inkjet printer, your printout will be lighter than normal, perhaps even unreadable. If necessary, change the cartridge and run the print job again.
If you're using a laser printer, you might get black streaks on your output. This problem is most often caused by an old toner cartridge, or by a dirty roller or printer cleaning bar. If you replace the toner cartridge and clean the suspect parts (using a cotton swab) and you still experience black streaks, your printer might need service.
If you're using an inkjet printer, it's possible that your print jets are clogged. You'll need to unclog the print jet by inserting a small pin into the jet.
It's also possible that a paper misfeed in your printer caused the printout to become smudged or out of line; if this is the case, straighten the paper feed and start the print job again.
An incorrect printer setup in Windows can also cause unusual printouts. Make sure that Windows is configured for the exact type of printer you're using. Also make sure that you have the correct landscape (horizontal) or portrait (vertical) printing option selected.
If none of this works, you probably have a problem somewhere in your printer. Although a bad printer port on your PC could be the culprit, more than likely some internal problem with your printer is causing the poor printout. (You can confirm this by printing a self-test page; if it looks bad, the problem is in your printer.) Consult your friendly repair center.
Problem: Your Printed Page Looks Half-Finished If you're trying to print a document with a lot of graphics (especially on lower-priced laser printers), you might find that your printer doesn't have enough memory to print the entire document. What you'll get is about half the document—and not always a contiguous half! You can do one of several things to rectify the problem:

If your printer prints like this:
with the any color printing faintly down the page, then the problem is with the developer blades in the imaging unit. What happens is there are metal blades that meter the amount of toner that gets put on to the drum that makes the image on the paper. The toner is made up of fine particules of plastic. As the printer prints, some of this toner collects on the edge of the developer blades causing less and less toner to make it onto the page making the print look faint.
To correct this problem, you either need to buy a new imaging unit or clean the developer blades. There is a document on the internet that gives a detail instructions on how to do this, but, the link no longer works. I have a copy of this document, I will try to post it if people are interested.
