I have an HP Officejet 6500 wireless printer that was working fine for the past 2 years. I replaced the three color cartridges with 3 that I'd bought over the internet as "remanufactured" cartridges. They wouldn't work as the printer refused to recognize that they were even there. Sent an email to the company I'd bought them from and they informed me that they'd had problems with those cartridges and would be putting 3 new ones in the mail. Fine. Got the new ones about 4 days later, installed them, and then the black cartridge that had been OK, was no longer working. Put the printer through the cleaning cycle enumerable times and nothing helped. Even tried blowing the little filter screens out with compressed air and that didn't help, either. Installed a new black cartridge and the printer recognized it as a refilled HP cartridge, but it still wouldn't print. In the meantime, the color cartridges are getting more streaky every time I put it through the cleaning cycle. I am assuming that the print head is not a part of these particular cartridges. If that is the case, how do I get to the print heads to clean them? Thank you
