Does anyone know if you can purchase a single yellow cartridge for a HP Photosmart B209a 3 in 1 printer. I continue receive error message stating - red, yellow, blue appear to be missing or damaged.

Probably bad, there's actually no way to check ink levels.

SOURCE: I have a hp 7580

Normal 0 Could have a corrupt driver.
Disconnect the printer or at least be sure it is turned off. I'd do both and when the CD software program asks you to connect the printer to the USB port, do so and it should again work properly.
Hope this helps. Bud

Something is wrong with your Blach carrier or connections. Use a bit of alcohol and clean the array of gold contacts where the Ink cartridge plugs in. Most of the pins are shutter and piezo control (get the ink on paper) but a few do other stuff like check ink level, # of hours runtime, etc. This is very common problem with inkjet printers. Hope this helps.
Also... rub the contacts on the printhead with a pencil eraser to make them shiny and bright.

Cheers!

Take the cartridge out and clean the contacts off with something (ie: pencil eraser, your thumb...) That worked for me! I couldn't find a solution anywhere even after chatting with online tech support from HP. Quick and painless! I hope this helps...

Well....I solved the problem......bought a new Canon printer!!

I tried everything...unplugging, cleaning everything that was mentioned above. I was onto HP online support several time, but they were absolutely no help at all...they basically told me that the cartridge must be damaged or ink dried up and to buy a new cartridge to see if the error persisted.....I don't think so!!!
I will never by HP again after having issues with the last two I have had. I love my new Canon printer it is EVERYTHING that HP wasnt.
