@charls83, Welcome to HP Support Community!

Going through the sample shared I see that you've scanning related issues on the printer This seems to be an issue with the scanner glass or the light. I'd suggest you follow the steps from the document Resolving Copy Problems to resolve the issue. If the issue persists, it could be a hardware failure.

Please reach out to the HP Support in your region regarding the service options for your printer.

Hope this helps!

I have brought your issue to the attention of an appropriate team within HP. They will likely request information from you in order to look up your case details or product serial number. Please look for a private message from an identified HP contact. Additionally, keep in mind not to publicly post personal information (serial numbers and case details). 

If you are unfamiliar with how the Forum's private message capability works, you can learn about that here.

Thank you for visiting the HP Support Community.

I will never buy a HP printer again.
I applied for an Epson printer with much cheaper ink cartridges.
Everyone who reads this should know.
Repairing HP printers is very difficult.
The reason seems to be the company that makes money from ink cartridges.
