Printing gray
On my black ink it is printing gray, installed a new black ink cartridge
and have unchecked grayscale. Cartridge is full of ink. Anything else I can do to sort this? |

Is this an old thread, or did you not provide any information on your printer at all? That would be helpful! Possibilities: 1) if test pattern looks bad, you have blocked nozzles preventing good coverage. So you should clean the printhead. If the printhead is on the cartridge, this will not apply to a new cartridge. 1) if black looks gray, you could be using a really low-quality draft mode, which always looks gray rather than black. Try a higher quality. 3) you could be using composite black instead of real black, which again looks gray since it is made up of CMY color. -- Gernot Hassenpflug |

The colour cartridge appears to print ok although it lacks `brightness`when printing colour (maybe not the correct word) due to what appears to be a lack of black ink being used in the production of the picture. The test pattern is ok. The printhead is on the cartridge. I will check your other points. |

I got tough with it and gave the print head a good clean with cleaner and now printing again, it must have been a blockage. I was on hols for 3 weeks and maybe it dried up a little in the `jets`. |

Interesting that you could print a test pattern which you say was OK. Then clean the heads to rectify the problem. I suggest that you find a decent test chart to check the nozzles. Even if one nozzle is down on mine it will upset the balance not sure what pattern HP print I have an Epson printer. Ill dig some up and post the URL tomorrow. |

I was never happy with the test pattern with HP so done my own which allows me to see the colours so I could understand them. When I ran this the tri colours were fine but the black was gray and there was no streaky lines to indicate a `dirty` nozzle. Thats what was confusing me. But as mentioned now sorted. |
