Hi! I have a huge problem with my hp deskjet 940c. It won't print colors - only pink! I have bought two new print cartridges, but it's still no good. The black one is okay. Can you help me?

HP 78 Tri-color Inkjet Print Cartridge (C6578DN)HP 78XL Tri-color Inkjet Print Cartridge (C6578AN)
HP 78+ Tri-color Inkjet Print Cartridge (CB277AN)

Good luck

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.

Hi

The printhead of your color cartridge is clogged
or is near to end
you need to replace the color cartridge or refill it (cheaper method)
check here how

the moving ink frame is probably pointing to a symbol such as replace color ink( three dots on ink cartridge picture). Replace color ink. You are probably printing your black and white documents with colored ink--always select black or greyscale.

Some HP ink refills have the exact same product number but the electrical contact tips on the back of the cartridge are not the same configuration, resulting in red ink only being printed. One example is the DeskJet color ink cartridge C1823D having multiple configurations.Find a printer just like yours that's working properly and compare the contact tips if possible. HP tech help is a joke on this one. Good luck!

You most likely need a new black HP 15 cartridge.

try aligning the printer from the hp solution center again..
hopefully it will work

Print a test page only in black. If little to no black shows, you need a black. If your color cartridge seems full, only get a new HP black ink cartridge.

I GOT A CLARIFICATION REQUEST AND I SENT FURTHER INFORMATION BUT AS OF YET I HAVE NOT RECIEVED ANY FURTHER INFORMATION BACK FROM "KEEPITSIMPLE".

First make sure that there is ink in the color cartridge. Take a damp cotton pad and put the cartridge on it for a few secs. This will bleed the colors out . See that you get all the colors. Then

Go to Control Panel> Printers and Faxes> right click on your printer's icon, go down to properties. There under advance, you can do a head cleaning. Under color management, set it to automatic.
Let me know the results.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe
