Hi Rick,
 
The Printer MIB did a bit of shabby modelling, because an Interlock
may protect a part (e.g., pinch roller) that is NOT a Cover (I've seen
MIB-walks of real printers that did this).

Locations in MediaPaths are often instrumented with Interlock sensors, 
although the thing being moved/removed isn't always a cover.
 
So, what about 'prtCoverTable' maps to 'PrintInterlock(s)', but
with a good Description cause explaining the legacy Printer MIB
modelling, and ADDING an 'IsCover' boolean property (defaults 
to 'false' of course) to disambiguate the two cases?
 
Cheers,
- Ira

Gee, I thought that Cover included Interlock and that they were already
thoroughly intertwined a decade ago by the TC that you cited.  It's only the
sensor that we care about, whether it's on a door or an internal component
-- for instance, if there is a door without a sensor, it certainly would not
appear in this group -- so I thought that interlock was the more general and
inclusive term.  
---------
PrtCoverStatusTC ::= TEXTUAL-CONVENTION
    -- This TC was extracted from prtCoverStatus in RFC 1759.
    STATUS    current
    DESCRIPTION
        "Values for encoding the state of a particular cover or
        access panel on the printer case or enclosure."
    SYNTAX    INTEGER {
                  other(1),
                  coverOpen(3),
                  coverClosed(4),
                  interlockOpen(5),
                  interlockClosed(6)
                  }
---------
But if the group wants PrintDeviceCovers, hey, I'm easy.  Other opinions or
suggestions?

Hi Rick,
 
[copied WIMS list to make others aware of these issues]
 
A Cover is NOT an Interlock (in the Printer MIB) - the Interlock is just the
sensor and logic.
 
Conflating Cover with Interlock will screw up the semantics of some widely
implemented existing values of 'PrtAlertCodeTC' as well.
 
In the WIMS and Semantic Model/v2.0 schema Subunits.xsd, the classes
are simply Cover(s).
 
I dislike abandoning Printer MIB terms - how about 'PrintDeviceCover(s)'?
 
Cheers,
- Ira

I think that PrintCovers is a crummy name for a class.  Almost everyone who
did not grow up with PrinterMIB would misunderstand the class until they
read the description.  I suggest PrintInterlocks.  In the Projector &
Display Management group, we are calling the comparable stuff the Interlock
Group.  (If there isn't a sensor on the door, then we don't care about it.)
Seem reasonable to use PrintInterlock as a classname instead?
