Top 20 HP Photosmart C6380 All-In-One InkJet Printer Questions & Answers

Suggest you return it and buy Canon or Epson

To see which color is having an issue, go to printer control panel and select "settings" > Tools> Print report> Print Quality report. When the page prints out, you will see which color is the problem. After you have figured that out, make sure the problem is not with the cartridge. If you see lines or missing colors, clean the printhead by removing it from printer(open cover, lift gray latch on the right side of the cartridges, remove cartridges and the printhead will easily slip out by pulling up) then soak the printhead in half inch deep amount of window cleaning solution. Preferably warm. Let soak at least 3 hours. Dry out the printhead and wipe rear conacts from moisture and dirt. Reinstall into printer and see the results. -Alex 303Electronics eBay Stores http://www.303electronics.com/ If you need further help, I’m available over the phone at https://www.6ya.com/expert/alex_22751bbefa74c3d0

You should be able to go into your printer preferences or properties settings by going to the "Printers & Devices" tab. If this is for Widows 8 or 8.1 I have not upgraded to either OS and have no clue as to their layout for access. In XP and 7 there is the option of changing your default settings from color/auto to black & white only. Make sure you hit the "APPLY" button to set it "OK" button doesn't always keep the settings locked in.

INSTALL ONLY BLACK CARTRIDGE THEN GIVE PRINT COMMAND.
