Is this happening when you print or when you scan? If when scaning you could have something on the scanner bed... If this is happening when you print, it could be the cartride is defective.

SOURCE: ink "banding" on hp laserjet 2600n

Viscosity of the ink is likely your problem. Sure the inks are not leaking at the same time, but that is likely because the different colors use different tints which can be slightly thicker or thinner. Many printer manufacturers (HP most notably) makes many patents on their ink, and not solely on the colors, but also the viscosity. The ink jets could slowly be leaking and might need to be replaced, finding these parts yourself might be easy, but replacing them is not.
I'm going to assume you've replaced the blue and suggest you remove the roller and clean it with glass cleaner. You may find it EXTREMELY difficult to remove the roller, so I would probably find a printer repair/ sales shop. Usually these places are not easy to find, so you'll probably want to find an office equipment sales business. These are the companies that usually sell the larger copier/fax/printers for large offices, or you could call HP and ask where a certified HP printer technician is in your area. I will tell you though, the cheaper ink may have just caught up to, having a copier technician repair this printer could cost quite a lot, but doing the job yourself, could be disastrous. The amount of small screws, easy to break plastic tabs, and interesting clips, etc make the job nearly impossible for a novice.
Good luck -Skyler

SOURCE: HP 6310 printer says HP 95 tricolor is empty.

It sounds like you need to replace the cartridge with a new one. The electronics may have went out. We see this usually during the winter months when the static electricity in the air is high and we shock the cartridge. I would also NOT recommend cleaning the head/jets of the cartridge with alcohol. The electronics are fine to clean with alcohol both inside the printer and on the c artridge, but the head will dry out. We recommend taking a damp warm wet paper towel, placing it on a protected surface, and placing the head of the cartridge on the paper towel until you see some ink appear. Then put it back in your printer and let the printer clean off the bottom. If the printer is not cleaning off the bottom of the cartridge, the printer cartridge wiper on the carriage may be broken or stuck.

Try Cleaning the Cartridges manually and automatically.
For the cartridge clean it with a damp lint free cloth and also for the printheads wher eyour gonna be inserting the cartridges.
Follow these steps do do the automatic aligning and cleaning:
Click Start and then go to Printers and Faxes (XP), Printers(Vista), Devices and Printers(Win 7)
1. Right Click on your printer Icon 2. Go to Printing Preferences 3. Click the Features Tab 4. At the bottom of the window you will see Printer Services or Device Services. Click on it. 5. Choose Align Printheads on the list.

For Cleaning the Printheads, Instead of choosing Align Printer choose Clean Printheads.
I hope this helped.
Try Printing Again. I hope I was able to solve your problem. :)

I have a HP 7590 printer and it sometimes skips line or some of the lines are faded when printing black .

Perform the following steps to reduce or eliminate faded or grainy lines:
  1. Print at a higher quality setting.
  2. Verify that the paper you are printing on will lay flat. Paper that is not laying flat can cause banding when the paper transitions over the rollers or cause the print cartridges to scrape across the surface of the page. Check the top sheet of paper by removing it from the all-in-one and placing it on a flat surface. If the paper does not lie flat, bend it in the opposite direction to straighten it.
