I'm sorry to hear you are having problems with your Officejet Pro 8600 Plus since upgrading to Mac OS X 10.9 Mavericks.
I have included a link to the full feature software and driver for your Officejet Pro 8600 Plus for Mavericks. I would recommend that you uninstall the printer and then re-install the printer with the full feature software and driver.
