HP OfficeJet G85xi Not Playing Nicely with Windows XP Tablet

I have a tablet PC with XP Tablet Edition on it. I installed my HP
Officejet G85xi (USB). The install went smoothly, but the HP
Document Manager did not install nor did I even get the option to
install it. I also cannot use the flatbed scanner with the Tablet
PC. I CAN print and do photocopies (from the control panel on the
printer), but I cannot get the scanner/copier unit to work from XP
Tablet Edition. I was wondering if it is a compatibitily issue? I
have not found much information on this topic so I figured I'd ask
around. Any information would be helpful. Thank you.
