I work at a preschool, and am the only one who even has the vaguest idea on fixing our computer and other hardware. That being said, I only have a basic understanding of these things.
Our HP Officejet 6700 Premium has not been printing blue or yellow correctly. It will either omit the color all together and replace it with something different, (I tried to print rainbow text, and it replaced yellow with off-white, and blue with green) and trierd to print some clipart of hearts, and ended up with blue lines running through the magenta. The printer is hardwired to the PC. I have replaced all the cartridges, even though there was no low ink message. This did nothing.
I also went through all 3 stages of printhead cleaning, which improved the color output a little bit on blue and green, but there are still lines going through both colors. I tried to align the printhead, and got an error mesage saying it was unsuccessful.
I was going to call technical support, as I have just read a similar question on this forum, and followed the steps provided, to no avail. I would rather avoid sitting on hold if I can get the answers here.
