Updating SANE (libsane1, sane-backends) from 1.0.31 to 1.0.32 could
perhaps fix the scanning with installed ipp-usb and the "escl" backend.
1.0.32 (released upstream a few weeks ago) has a lot of fixes and
improvements on the "escl" backend.
You could install sane-airscan. This is an extra SANE backend which
provides more sophisticated support for driverless scanning (scanning
with ipp-usb, "IPP over USB" always uses driverless scanning and
printing standards).
Classic drivers (as HPLIP's "hpaio" work only without ipp-usb.

Dear Maintainer,
I recenty realised I cannot scan with my scanner (part of a multi-function
printer/scanner HP Deskjet 5275).
Disabling ipp-usb enabled scanning.
