HP Photosmart Pro B8300 - Mixed or Missing Ink

The document applies to HP Photosmart Pro B8300 Printers.

Issue

You printed a self test page and found colors that are very different from the colors on the cartridge label, or entirely missing colors.

Solution

Step one: Run the clean print cartridges utility

  1. Verify that the printer is on and connected to the computer.
  2. Click Start and then click Control Panel.
  3. Double-click Printer and Faxes.
  4. Right-click the name of the printer and then click Preferences.
  5. Click the Services tab.
  6. Click Service this Device. The Printer Toolbox opens.
  7. Click the Device Services tab.
  8. Click Clean the Print Cartridges and then follow the instructions that display on the screen. Up to three levels of cleaning are available.
  9. Discard or recycle the page that prints.

Step two: Replace the problem cartridge

If the problem has not been solved by the steps above, either the printer or the problem cartridge is defective.
  • If you have not tried cartridge replacement previously to solve this problem, replace the problem cartridge now. To see if your cartridge is covered under warranty, refer to the Inkjet Print Cartridge Warranty Quick Reference.(c00059195) (in English)
  • If you have already tried cartridge replacement and it did not help, service the printer.

Preventing color mix and missing colors

Color mix is usually the result of a non-porous material contacting the nozzles. Missing colors occur when the cartridge nozzles dry out, or when a color is exhausted because of specific printing demands.
  • Do not remove the protective tape from a new print cartridge until just before you install it. Once you remove the tape, do not reapply it.
  • After you have removed the protective tape, do not allow anything to touch the nozzles.
  • Print at least once a month to keep the print cartridges in good working order.
  • Always turn the printer off by pressing the button on the printer control panel, rather than by unplugging the printer. Turning the printer off properly allows it to protect the cartridges.
  • If you are removing a cartridge from the printer temporarily (for instance, removing the black cartridge in order to install the photo cartridge), put it in a cartridge protector.
  • If you do not have a cartridge protector and need to remove a cartridge temporarily, put it in an airtight plastic tub. Make sure nothing touches the nozzles. Do not use a plastic bag. If you intend to store print cartridges in a tub for a long period of time, place color cartridges with the nozzles down, and black cartridges with the nozzles up.
