HP LJ 8000dn added tray 4 & 5 but the LJ 8000 win xp driver has tray 4 and 5 out of focus

Hello All,

I have an HP LJ 8000 DN. I added trays 4 & 5 and a duplex unit to it, but the win xp HP 8000 pcl driver show those trays as out of focus, so I can't change the status. The duplex option in the driver is in focus and is changeable.

Any ideas why. Do I have to re-install the driver?

Thanks
