Our suggestions actually doesn't controvert :-)

You may try sane-escl or sane-airscan, or even install and try both and 
choose whatever you better like. But please replace ippusbxd with 
ipp-usb in any case. ippusbxd is broken and cannot be fixed, it is 
officially deprecated and replaced with ipp-usb.

Regarding Epson's imagescan, it is very unlikely that its USB version 
will work together with the IPP over USB daemon running; they will not 
be able to share USB interface. Basically, for devices like yours, open 
source alternatives work more reliable, that proprietary drivers, but 
may expose less hardware features, so don't use imagescan unless you 
really need.
