Question about HP PhotoSmart 7760 InkJet Printer
My printer usually prints gorgeous photos and the colors stay very true to what you see on the screen. When the ink starts to run out, the pictures tend to have a yellowish tint. Today I bought NEW ink cartridges and my pictures still look yellowish... Or at least much more pale than they are on screen/they usually look when I print. Any ideas?
SOURCE: will not print at all
You can try restoring the printer to factory settings..and try agian it has worked most of the times for me..Let the catridge be in the printer when you do this..

On the left side of the print head carriage is a white plastic gear that drives the ink pump. Check it first to see if its firmly in place, has chipped or worn off teeth or looks damaged in some other way.
If this white gear driving the ink pump is damaged or looks odd let me know right away so we can address this issue.
Now, there is a trick for resetting your particular HP printer. This sounds and is convoluted but it will work. However, the system will think all your ink cartridges are full. If they are rather full okay. If they are near empty you will want to run this hack again as the ink nears low. You won't get a ink low warning correctly after this until you've installed new full tanks eventually.
Turn the printer on. At the same time, using your left hand, press the OK, Cancel, Black, and Color buttons down and hold them down. While holding these down buttons use your other hand to turn the printer off, still holding the four buttons down with the left hand. Once the printer has powered down fully you can release the buttons. Now, the printer will initialize and then run a maintenance check. If you printer is otherwise okay, no damaged circuitry or gearing you will be fine. Turn the printer on. It will start up and shut itself off, this is expected. Once it is off again, turn it back on once more and this time the printer will run the maintenance routine. Have paper in the feed tray.
1.) Check left side of printer carriage for the white gear that drives the ink pump. Look to see if the gear is off, broken has worn or chipped teeth.
2.) Turn the Printer On.
3.) Hold down the OK, Cancel, Black, and Color buttons with your left hand and hold them down.
4.) Use your other hand to turn the printer off. Keep your left hand on the buttons until the printer is off.
5.) Turn the printer on, wait for it to turn itself off. Have paper in the feed tray.
6.) Turn it on again and it will enter the maintenance mode. Follow any prompts during the maintenance mode, if any.
You should be back in business now. If not, try the routine again, sometimes you have to run it more than once. Should it still fail, let me know as you may get an error message and error number.

Does the c7280 use seperate Magenta and PhotoMagenta cartridges? If so make certain the right cartridge is in the correct slot.

I have this same problem and some sites said to uninstall the software then download the software from the HP site and reinstall it. So I am giving that a try tonight
