@Alvin76, Welcome to the HP Support Community!
It looks like the ink could have dried up. Check the ink levels, clean the ink cartridges up to 2 times, and print a quality report to check the result as shown in this document - Color or Black Ink Not Printing
If the issue persists, we may have to replace the ink cartridges. As this printer does not have a screen, the only way to obtain the claim code is to print it.
Once the printer is able to print fine, you may refer to this document to know how to print the claim code.
Hope this helps! Keep me posted.
