Won't color print

Ink levels are an estimate. They are approximated according to how much color might have been used. You may be out of all the color inks, they may be dried out or clogged. There should be a head cleaning operation for the printer, but it uses ink too.

You can only use the black ink cartridge without the color ink. But no need to replace them in your printer.
When you print just choose black and white for the printed text must be black not colored. But if you still received such notification...just try to replace the color ink cartridge to continue printing
Note: As per my experience. printer with exclusive black ink alone will damage the printer easily due to unbalance printing of ink

I also faced the same problem. You can try the following steps to fix this issue:
- Check ink cartridge
- Reset your printer
- Clean print-heads
- Check the printer's color option

I also have the OfficeJet 6500 and had the same problem. The black text was printing using a mix of colored inks instead of the black ink, resulting in a grey, fuzzy text. I finally found a solution. In each application under Page Setup, there is an option called "Format for". Mine had been set to "Any Printer". I changed that to "Officejet 6500 E709n [830E4A]" and now it prints the black just fine. I have a Mac running 10.4.11. Hope this helps.

go into your driver and change your color preferences to black and white. that way when you want to print color you actually have to tell it to do so. which will save your color ink, and will print much faster. full color printing of a black and white document uses all ink colors except black to make what is called process black.

The reason why the printer refuses to print if you get low on one or more colors is that the system runs off negative pressure through the ink lines to the print head. If you were able to continue printing with an empty cartridge you could get air in the respective ink line, disrupt the negative pressure, make it so that that color will no longer print, and require you to get the printer serviced to fix the problem. I own a Cartridge World ink refilling store and I feel this is a good machine (compared to some of the others out there). The only down side with this type of machine is the print heads expiring or getting clogged as you are experiencing. The reason the black is clogged and not the other colors is that the black ink is pigment based and the colors are dye based. The pigment based inks do tend to clog print heads over time. You can try to rehydrate the print head with warm distilled water. if you can't get it working to your satisfaction you can buy a new black/yellow print head for $72. With this type of printer you should print at least one black and white and one color document per week to keep the print heads fresh. If they sit too long without ink flowing through them then they can get clogged and print poorly. I hope this helps belay some of the resentment you hold towards your printer.

You may try and change the setting in the printer and fax option in the control panel.
