I have the same problem. My printer is only 2 years old and all of a sudden it stopped printing in black. I replaced all the ink cartridges and the printheads and it still wouldn't print. I tried HP solutions, but to no avail. Local repair shops all suggested to buy a new printer since that would be cheaper. I finally resigned myself that this could not be fixed (at least not at a reasonable price) and was lucky enough to find another NEW L7680 on e-bay for a very good price.

SOURCE: hp psc 1510 - only want black ink

Hi Manavoc,

I will explain you the cause for it.

It prints in yellow first and then override with black for better quality. This is the reason your color ink gets empty.

Have a great day!

SOURCE: new black print cartridge not working

I only use refill HP inks. When the cartridge prints gray instead of sharp black it means the ink well is clogged. Yes, that can happen on a new cartridge. Sometimes it happens when they put too much ink in the cartridge, or even heat can make it not work. Also streaking black lines is the problem of the ink not coming out properly. Easiest thing to do is go to a refill station like Cartridge World and have them test it or clean it out. You can also make sure the printer, not the cartridge is clean. Ink builds up an pools. Get some Q-Tips and clean up all that spilled ink. Sometimes in the software it says you can clean the print head, do that too.

SOURCE: printer replaced with black cartridge, and doesnt print

Either the print head for black is faulty, or the wiring to the black print head on carriage are broken. Try also cleaning the metal sensor to the black cartridge inside the ink carriage.

In my pixma ip2772,when I print photo then black colors are printing properly but when I print any types of documents then my black color is not working.It's not showing dark.What can I do?

This printer has a separate cartridge for black and colour. When you print pictures, the printer uses all three colours mixed together to make black and does not use the black cartridge. Your black cartridge may be empty or the printhead may just be dried out. Try a head-clean from the maintenance menu and then print a nozzle test. If still no result then try replacing the black cartridge with a new one which has a new printhead as part of the cartridge.

My cyan cartridge shows as empty. My black

No. You need all the cartridges installed with functioning chips for your printer to work. The reason why you need all the colors when all you print is black is because a small amount of color prints when you print black. The manufacturers want to make up their R&D costs on the printers by selling lots of expensive ink.

Lexmark X1100 printer will not print black

I came up with a work around for printing black.

I changed the black cartridge with the color cartridge.
Then when I have a letter to print, I change change (or write) the letter text to yellow, red or blue.
Then I can print out a letter.

By printing the text as yellow, red or blue the cartridge will try to print with only 1 color, but will print out black.

If you do not use one of these primary printing colors the out put will be unusable.

I can not of course print out pictures.

Hp officejet 6110 not printing with black ink

Hi lilacky-

Here are some HP support links that might be helpful... and a couple questions to consider.

Q: Is your new cartridge one of these listed below?
"The HP Officejet 6100 series and HP Digital Copier Printer 410 products use the print cartridges listed below:
* HP 56 black print cartridge
* HP 57 tri-color print cartridge
* HP 58 photo cartridge (replaces the HP 56 black print cartridge for six-ink photo printing)" info from: Installing a Print Cartridge
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00004340&lc=en&dlc=en&cc=us&lang=en&rule=12548&product=79477 Is your new cartridge a refilled cartridge? Some times those have special challenges. Has your cartridge been sitting a while in the box, maybe in a warm spot? Some times even new cartridges dry out a little. Was your old cartridge low or completely gone? Just as a test, if you put it back in your printer does the old cartridge work? Any printer error messages? Can you print a test page or an alignment page for your black cartridge? These might be too many questions but here are some HP support links with some How To information for getting more answers. Please let me know if any of these are helpful. see also: Slow or No Response from Printer

Ink cartridge light keeps blinking BEWARE SPAM NUMBER 1-800-532-4187

you need to print only in black if that is all the ink you have, and also you need to remove the color cartridge as it still registers in the printer as able to be used, although it is empty or near so. Did you remove the tape over the print head fron the new ink cartridge? Do a print head alignment, or use the toolbox icon to tell the printer that you just replaced the cartridge. Some HP models chip the ink cartridges so even a refill wont register as a full tank and the printer wont print. chip needs to be reset (difficult) or just replaced with a new cartridge.
