HI Penny--

Wrong syringe selected?  Check method to see what syringe it uses, the 
do the "chg syr" and select the correct one.  We've turned our syringe 
detection off, so we have to select ours manually.  Also, the tray used 
by default is "tray01".  If there isn't a "tray01" defined, that may 
cause problems too.

good luck...

gerry
