what sort of documents are you trying to scan? xerox machines have difficulties trying to make searchable scans from images... then it takes a verry long time....
ist better to create 2 templates, 1 searchable the other one not
also, what firmware is your machine on? xerox fixed lots of scanning issues in the 19700 and further release
latest one at the moment is :
example from rls note:
scanning multiple Scan to file jobs, intermittently some of the jobs do not
file, but a failed confirmation sheet is not printed.
scan jobs go into processing then delete without error sheet
