You don't, if it existed it wouldn't matter since this printer isn't looking at it.
Either the printer you are looking at physically is different than the one you are viewing in CWIS, or it is horribly broken in some way (corrupt)
A quick trick is to create a scan template that already exists on the printer to see if it forces them/it to show up again in CWIS, or try restoring the defaults in the default template (re-syncs the HDD and ESS PWB)
Failing that, a tech would need to do a Diagnostics mem clear (Instructions will not be provided here, it is not publicly disclosed information)
