Manual feed in LrC

I am trying to print a simple 8 x 10 photo using the normal page feeder (not the manual feeded). I have the correct paper size selected in LrC and the printer has sheets of letter size paper ready to print.

For some reason the printer (Canon Pro-10) gives me an error message "start manual feed printing". I don't want manual feed, but I can't figure out how to change it, so it is not manual feed by default.
