Hi! My 6500 all in one is no longer printing the cyan cartridge. I changed the ink cartridges last week and ever since then, the cyan will not work. I thought I might have a bad cartridge, but when I reinstalled the old cyan, it still didn't print. On the test page it has the place for the cyan with the cartridge expiration date so I am assuming that it is reading the cartridge, but the little box that should be full of blue ink is empty.
I have cleaned the cartridges, and the printer head as instructed by HP manual, but nothing is working. I've already used 1/4 of my other cartridges just in printing out test pages to see if cyan is working... any suggestions?

Have you tried cleaning the printhead? (see step 5)

I changed my black cartridge yesterday and am having this problem.
The ink pad is ok to the touch, and I can hear ink in the cartridge, but when I print or copy, page is blank.
If I opt for colour print, other colours print ok. leaving blank all black type.
Did you get sorted with cyan cartridge? If so How? Thanks
Please please help

Hi, have you checked the cartridge is vented properly?
Figure 14: Correctly vented ink cartridge
Figure 15: Vent clogged with adhesive

I just checked the cartridge vent and it looks fine, no adhesive blockage. Also, I've tried replacing my new cyan cartridge with the old one to see if it was a cartridge issue, but then the old cyan cartridge wouldn't work either so I don't think it is related to the new cartridge. It is very frustrating because the printer was working fine until the cartridges were replaced (about 2 weeks ago) and since then, the cyan has stopped working...

Some folks have found that soaking the printhead can work well. See details in Bob's post below

My theory was that since machine and other cartridges were working OK, then issue must be with black cartridge. I figured that if I replaced it with another new cartridge and that didn't work, then blame would rest firmly on the machine itself.
I have just installed the second new cartridge and printer is working perfectly!!! So looks like problem was a dodgy cartridge. Hope this works for you.
