Office Jet 8620 Error 72234 printing blank pages

[DJ-42]

I hope this community can help!

I have an HP Officejet Pro 8620 which acts like is printing but only prints blank pages since replacing the printhead with OEM HP printhead CR322A. The printhead was replaced because the printer reported the printhead was missing or damaged.

1. Installed the new printhead w/the supplied printer cartridges and the printer reported "Do not use SETUP printer cartridges".

2. Replaced supplied printer cartridges with the cartridges from the "failed" printhead. This eliminated the SETUP printer cartridge error message. 

3. Ran "Align Printhead", "Calibrate Linefeed', and "Clean Printhead" multiple times, with the same result ... the printer acts/sounds like it is printing but spits out a blank sheet and a "Align printhead unsuccessful" message.

Actions taken:

1. Reseated printhead multiple times (unplug unit/release printhead/remove/inspect/wait 60 secs/reinstall, gently moving printhead side-side to ensure it is seated/secure printhead/close door/plug in).

2. Confirmed ink levels are @ 1/2 to full

3. Confirmed firmware is current.

4. Inspected printhead and contacts for debris while carefully ensuring to not touch them.

I am at a loss for what more I can do. I'm hoping some tech-savvy person on this board has a solution...or am I now the proud owner of an 8620 boat anchor?
