The issue is clearly related to bidirectional alignment. At this point we have done everything I can think of to address this. Sorry, I do not have any further suggestions. I will ask for an HP Support person to take a look at this thread.
From what I can see, it looks like Bob_headrick has guided you through all of the necessary steps to troubleshoot the issue you are experiencing. Personally I suggest replacing the printhead, in the same breath I could also recommended you consider a newer printer model. It is entirely possible the issue is the printer itself and not the printhead at all. Perhaps it would be best to call us to discuss your options. You can find out the cost difference between replacing the printhead, and upgrading the printer. Keep in mind, if you get a new printer, it will come with a full set of ink, put you back into an 'in warranty' status, and be in working condition of course.
What you can do, is use the following link to create yourself a case number, then call and it may help speed up the call process:
Step 1. Open link: www.hp.com/contacthp/ Step 2. Enter Product number or select to auto detect Step 3. Scroll down to "Still need help? Complete the form to select your contact options" Step 4. Scroll down and click on: HP contact options - click on Get phone number
Case number and phone number appear.
