Cannot prink anything in black from my HP officejet 6500, have changed cartridge, colour print all ok

Select print in grey scales only in printer properties while shooting the print command, printer is using color cartridge instead of mono cartridge..

This printer having four cartridges and two print heads.Each print head having two pens, black, yellow & magenta,cyan. As you said yellow & black are OK.. So replace Magenta & Cyan print head..

What about print head?.. perform print head cleaning process through tool box, check any back print out? no remove black/yellow print head clean nozzles manually, try it if not resolved replace print head..browse the link how to clean the print head..http://www.ehow.com/video_4974250_manually-clean-hp-inkjet-cartridge.html

Hi

Black is not True black. It is slightly brown.

Printing in black uses mainly black but may also a tiny amount of a mixture of some of the other colours.

To minimize the usage of other colours:

HP Solution Center > Settings > Print Settings > Printer Settings > Color > tick Black Print Cartridge Only > OK.

HP ink can be expensive. It is possible to economize on HP inks in some cartridge formats by using Ink refill kits.

I hope this helps.

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.

Lift the top of the printer by applying pressure under the control panel. It might be quite stiff.

The print head will move into view and you can then release individual cartridges using the tab on the front edge of each cartridge.

Be sure to put them back in the correct location by referring to the colour coded marks on the print head, then gently press down until you hear a click.

When you are done push the lid back down and the printer should indicate that new (genuine) cartridges have been fitted. Press O.K.

My printer did that a few months ago. I tried everything to get it printing black but in the end I had to take the ink cartridge back and return a new one. Some ink cartridges dry out when they are being shipped if not stored in proper conditions.

Your colour cartridge must print OK for alignment complete.Try to change it.

This cannot be done! You need to have the colour carts in the mnachine otherwise it fails its startup diagnostics and will not print.
