Hi Nancy,
Thanks - I tend to agree.
So here's a suggestion with a rationale. I propose the
new term 'Scan Subunit', by analogy to 'Scan Service'
and 'Scan Device' (aka Scanner).
This causes least breakage in WIMS/1.0 and SM/2.0 schemas.
Where we enumerated service and device types as above (i.e.,
the function term with a 'service' or 'device' suffix) and
named our classes (and schemas) accordingly. The only
affected existing schema would be 'Subunits.xsd'.
It's important to note that we agreed several years ago
in WIMS protocol and Counter spec work that we would NOT
use the term 'Printer' (too ambiguous, due to IPP usage
to mean a 'Logical Printer'), but rather 'Print Device'.
So we should NOT use (in the formal MFD model) the term
'Scanner' to mean 'Scan Device'. We should instead avoid
the use of the ambiguous term 'Scanner' entirely.
Cheers,
- Ira

Ira,
Thanks for the comment.
I think it's better to use a different term than "scanner" for the scanner subunit. Let's discuss the group's concensus, or whether this should be discussed in the WIMS instead of the MFD WG in the Thursday teleconference.

Hi,
Good minutes, as always - one comment about 'Scanner' subunit.
In WIMS/1.0 (an approved PWG Candidate Standard) and thus in
Counter MIB v1 (an approved PWG Informational Specification),
there is a subunit named 'Scanner' that corresponds to the
'Marker' (used in Print Device).
The confusion occurs because of the use of the obsolete (and
ambiguous) term 'Printer' to mean 'Print Device'.
Thus, the WIMS XML schemas (and Counter MIB enumerations) name a
'Scan Service', 'Scan Device', and 'Scanner Subunit'.
MFD modelling work should NOT overload the ambiguous term 'Scanner'
to mean 'Scan Device'. The 'Copy' and 'FaxOut' services will also
use the 'Scanner Subunit', but that does NOT mean that they will
use the entire 'Scan Device'.
If we wish to replace the term 'Scanner' (for the subunit) with
some other term, then we need to make this decision and come to
concensus quite quickly, since it breaks the 'Subunits.xsd' XML
schema in WIMS and the 'IcSubunitTypeTC' textual convention in
the Imaging State and Counter MIB (soon to move to PWG Last Call).
Cheers,
- Ira
