I would first perform print quality tests to confirm that all printheads are sound and working properly. Then I would update the firmware. Then trying reprinting, if you still get the issue, try printing a different file. This type of corruption could simply be a bad driver or corrupt file.

If you find the information provided useful or solves your problems, help other users find the solution easier by marking my post as an accepted solution. Clicking "yes" on "was this reply helpful" also increases the chances that this solution will help others.

Thank you for the suggestions. I did all that before posting the question here and did not work.   You are right on the corrupt file - I  found yesterday that if I print it use an USB stick instead of sending it to Z9 from my Mac the poster is normal!  So somehow my Mac version might have corrupted the file - from user's new Mac OS.  Thank you for volunteering you time to reply to me, appreciated!   -Hongyan
