In your post from Friday the cyan was not printing on your Offciejet 8500 printer. Did replacing the cyan/magenta printhead resolve that issue? The alignment process requires black and cyan to be printing properly.
The answer to the alignment failure is the following:
After replacing the printhead, each time I attempted to print I was given the alignment request on my computer screen. It would attempt alignment either before or after printing depending upon my choice on the screen and always the allignment would "FAIL" and the warning would repeat upon the next print request. This must have happened over 30-40 times with a great waste of paper no less ink.
Something must be preventing the alignment, and after repeated fits of anger at HP for their stupid printer, I again attempted to align the print heads but this time I went to the printer itself not through the software on the computer. Upon reaching the Tools screen on the printer face and selecting Alignment the process completed correctly the first time.
Therefore, the alignment needs to be accomplished not through the computer sorftware interface which was requesting the alignment and starting it BUT with the printer ITSELF! Assuming that the computer software interface was the same as selecting alignment on the printer itself was the point of failure!
