Welcome to the HP Forums. I would be happy to help you with your HP Officejet Pro 8625 printer. I understand that you are getting carriage jam issue and you have already done some preliminary troubleshooting.
Don't worry though as I have a few steps to determine the issue and find a solution as well,
Turn off the printer, and then on again.
Clear any jammed paper from the printer.
Make sure that the carriage can move freely.
Remove and then reinstall the cartridges.
Plug the printer directly into a wall outlet
Reset the printer.
Click here and follow the steps mentioned in the document to perform above troubleshoot this issue.
Let me know how it goes,
