Why can't I print black on Photosmart C6380?

[swingdavid]

Is there an expert on-line today as advertised? Last evening I asked this same question but got no response. I've done everything suggested (pre-set, disconnecting and re-connecting cables, checking ink levels, etc. I've even re-installed the printer into my Windows XP. To no avail. I can print color but without the black tones that are required to make a faithful picture. What can you tell me TODAY that will forestall the purchase of an Epson that will enable me to continue my business routine?

I was of the impression that I would be able to have a live chat with someone on this special day. Was the event misrepresented? Or was I directed to the wrong page when I clicked on the button to join the special day's event?

Please be aware that this forum is a peer to peer support forum, it is not a direct link to HP support.  On Expert Day there are many more HP folks and other experts online, but it is still a forum and not a "chat".

For your issue the troubleshooting page here may help.  Are you printing on plain paper or photo paper?  If plain paper then the Black  cartridge (with the pentagon symbol) is the one to check.  If you are using photo paper then the Photo cartridge (with the bowtie symbol) is the one to check.  If the troubleshooting steps in that page fail then see the page here.

You've done your best but there's no way I'm going to do that last step of checking to see if the assembly is defective (hot water etc.).  After cleaning I printed a test sheet that showed all the colors as they should be but there wasn't a speck of black. I'm giving up because if the problem is indeed the printhead assembly I'll have to pay for a new one, install it myself and hope for the best. Easier to go to Staples or Target and buy a new one --- brand to be determined.

I should be back in business before the day is through.
