Replaced color cartridge in deskjet 6127. printer

you are having a defective printer head so just got it replace or get another printer

INK PROBLEM
Inkjet printers need to be used frequently to prevent inkdrying out and blocking the print head nozzles.
If the print head cleaning maintenance routine does not clear the blockages,then print head needs replacing, but it may be expensive.
It may be more cost effective to buy a later model and better printer thanreplace the print head.

Try to re-insert the color cartridge into the printer and make sure it is properly seated in the cartridge carrier.
If that doesn't help, try to clean the print nozzles. Please follow the steps below:
1. Press Copy. 2. Press Options until Maintenance appears on the display. 3. Press the right arrow until Clean Cartridges appears on the display. 4. Press Select. A nozzle page prints, forcing ink through the nozzles to clean the clogged nozzles. 5. Print your document again to verify that your print quality has improved.

change color cartridge then clean color head

that is because ur head of ur printing cartridge is damaged.

remove ur cartridges black as well as color
n install only black cartridge n check d blinking of lights on ur printer if it doesn't blinks it's mean ur black cartridge is OK but ur blinking of light on ur printer is same it's mean ur head of black cartridge is damaged
after this process remove the black one cartridge and install the color one cartridge n check d blinking of lights on ur printer if it doesn't blinks it's mean ur color cartridge is OK but ur blinking of light on ur printer is same it's mean ur head of color cartridge is damaged
now take a dry cotton cloth n gently clean ur cartridges head install both cartridges on ur printer n check ur blinking light on ur printer that will work only if u r too lucky other wise u have to purchase a one cartridge.

Make certain that the cover is off the jets - if you forgot to pull the strip off or it broke leaving part of the tape on the cartridge, it won't work. Try to do a clean process on the cartridge. If that doesn't work, and you don't have another printer to try the cartridge in, return it to the place you bought it and get another new one. If the printer is printing pink, the color cartridge is probably empty also so that it cannot make black from the other colors. These sound like refilled cartridges - OEMs would have failed with some form of error code or warning.

Remove your printer from the PC and uninstall the printer software. Now reinstall the printer software and connect the Printer to be detected and installed. Check printer properties to see the ink levels.
Use head cleaning before a test is taken . It is possible that the head is not reacting to the need of the command , can be an issue with ink drying , can also be poor ink cartridge contacts

If the Cartridge and printer alignment is successfull and you are still not able to print in color, mostly the Color print is disabled in your pc

from what I read on line at HP forums unplugging the network cable may fix it. Others sat they had to buy a new printer
