How do I print in color from Dell vostro 220 to HP Deskjet 6940 printer


Hello,

1. Check if the printer has colored ink.
2. Check the settings. Make sure that the colored ink is activated.
3. Update the driver for your printer. Scan your computer with RadarSync.

Let me know if you have any questions.

HP 6940 won't print black-new cartridge installed-prints color but no black


In all likelihood your print head has become clogged at the black ink outlet. Be aware that printheads can BURN OUT if you keep trying to print and there's insufficient ink reaching the printhead. The ink flow is relied upon to prevent overheating of the tiny resistors at the printhead. Best bet is to remove the cartridges from the printhead and then remove the printhead and try to clean it in warm water. You will find many youtube videos on suggestions for cleaning the printheads on HP printers. Do a google search for your model. If all else fails you can order replacement printheads for the part that has failed. They are not cheap so price compare. Oftentimes they will cost nearly as much as a new printer!

Which lights for ink mean what? I know the triple is color, but there are 2 single lights and only one spot for black. It is full but the first light stays lit and it won't print.


The left lamp is for color cartridge, the right is for black.If one of them blinking mean the ink cartridge missing or printer not recognize it.

I might have an idea why this is happening....The print cartridges might need cleaning...
Follow the steps below to do this....


Step one: Remove the black, photo print cartridge, or the gray photo print cartridge

NOTE:
The black, photo print cartridge, or the gray photo print cartridge is in the right side of the carriage. -Lower the cover of the product.
-If the print cartridge status light flashes, proceed to Step two: Replace the print cartridge.
If the print cartridge status light is off, proceed to Step three: Manually clean the print cartridge.
Step two: Replace the black, photo print cartridge, or the gray photo print cartridge and remove the tri-color print cartridge
- Remove plastic tape from new ink carttridge CAUTION:
Do not touch the print cartridge ink nozzles or copper contacts. Touching these parts will result in clogs, ink failure, and bad electrical connections. Do not remove the copper electrical contacts.



NOTE:
The tri-color print cartridge is in the left side of the carriage.
-Lower the cover of the product. -If the print cartridge status light stops flashing, proceed to Step three: Manually clean the print cartridge.
If the print cartridge status light still flashes, replace the tri-color print cartridge. If the issue continues, service the product.


Step three: Manually clean the print cartridge
1. Gather the following items to clean the print cartridge and carriage:
o Clean distilled water. Use bottled or filtered water if distilled water is not available. Tap water can contain contaminants that damage the cartridge.
o Clean cotton swabs or any soft, lint-free material that will not stick to the cartridges (coffee filters work well).
o Sheets of paper or a paper towel to rest the cartridges on during cleaning.
2. Open the product cover, and wait until the carriage stops moving.
3. Remove the print cartridge, and place it on a piece of paper with the nozzle plate facing up.

NOTE:
Clean the contacts quickly so that the print cartridge is not outside of the product for more than 30 minutes. If the cartridge is outside of the product for too long, the ink can dry and clog the nozzles.
4. Unplug the product.
5. Dip a swab in the clean water, and then squeeze it to remove most of the moisture. The swab should be only slightly damp.
6. Clean the print cartridge contacts. Do not touch the nozzles.
7. Clean the contacts in the carriage, inside the product.8. Either let the print cartridge sit for ten minutes to allow the cleaned area to dry, or use a new swab to dry it.
9. Reinstall the print cartridge.
10. Plug the product back in.
11. Close the product cover.


Good Luck!
If there is anything more I can do for you please let me know if not and the problem is solved please rate it, Thanks, JCE

The black is printing dark redish brown


Dear friend, your Black Ink Cartridge is Empty thats why your printer is using the Colour Cartridge to produce the Black Colour. This is the reason you are having Dark Reddish Brown colour instead of Black.

HP Deskjet 6940 not printing after replacing ink cartridge


My HP Deskjet 6940 is not printing. The color (left) low ink light is dark and the black (right) low ink light is flashing. I replaced the black ink cartridge with a new one but the low ink light continues to flash. No tears/rips in the circuit strip and all the copper leads appear to be connected

Printer Toolbox Not Recognizing New Black Ink


The Deskjet 6940 will only show ink level for original HP cartrdgies. Refilled or reman cartridges will show as empty or unknown in the toolbox. This is not an issue with the driver, the cartrdige itself has information that it has been previously used and this is not resettable. You can continue to print with a cartrdige that has unknown ink levels, you will just not get low ink warnings.
