I finally fixed it. I had the same error for a long time.
Frustrating,
isn't it!
I was online with HP support for hours.
It boils down to this. At some point, somewhere, somehow, all of you
either deleted or uninstalled some printing or imaging software
components
from HP.
If you have any CD's of recently installed printer software, like I
did,
insert the DVD/CD when prompted to install the TrayApp. Then,
navigate to
the folder on the disk called, "TrayApp", in there you will find a
.msi
installer called, "TrayApp".
Click on that, hit OK and the Imaging Monitor should extract the
trayapp
automatically.
Tray App installers are on the Image Zone Disks that came with your
computer and almost alway on printer software installers.
Good luck.
Dave
