When I first read about using the generic Alert Codes, I was concerned =
with being able to report the failure with enough detail in a device =
that has multiple parts that could be over/under temperature. I thought =
that prtAlertGroup would indicate Marker and the AlertGroupIndex could =
only point to the single marker. Then I was talking to Lloyd and it =
looks like the following would be more appropriate.

If you go with the generic subunit error reporting, then you must add =
printHead(23) to the PrtMarkerSuppliesTypeTC list. This assumes that you =
consider the print head to be a marker supply. This will allow the =
failure to be reported with the following:

prtAlertGroup =3D markerSupplies(11)
prtAlertGroupIndex =3D value for the print head
prtAlertCode =3D subunitUnderTemperature(tbd) or =
subunitOverTemperature(tbd) or ...

Any thoughts?

Jeff's solution 1.2 appears reasonable to me. If there are not
any objections, I will include solution 1.2 in the Printer MIB.

MARKER ISSUE - Event codes for Thermal Transfer/Direct Thermal Print =
Heads.
In trying to come up with a PrtAlertCodeTC for thermal transfer or =
direct
thermal label printer print heads to report problems, I reviewed the
PrtAlertCodeTC section for the "Marker group". This group lists the
following enumerationIs:
-- Marker group
markerFuserUnderTemperature(1001),
markerFuserOverTemperature(1002),
markerFuserTimingFailure(1003),
markerFuserThermistorFailure(1004),
markerAdjustingPrintQuality(1005),
I would have to say that the term "fuser" applies to laser technology. I
donIt think this term applies to direct thermal or thermal transfer
technology. So to allow thermal transfer, direct thermal and any future
technologies to be included, There are a couple of ways that the
enumerationIs can address this issue.
>>> SOLUTION 1.1
Create the following enumerationIs in the Marker group:
markerPrintHeadUnderTemperature(tbd),
markerPrintHeadOverTemperature(tbd),
markerPrintHeadTimingFailure(tbd),
markerPrintHeadThermistorFailure(tbd),
This was my initial suggestion. I asked Tom Hastings about these
enumerationIs at the Nashua meeting. Tom suggested that a generic event
code
may be more appropriate.
>>> SOLUTION 1.2
Create the following enumerationIs in the subunit group:
subunitUnderTemperature(tbd),
subunitOverTemperature(tbd),
subunitTimingFailure(tbd),
subunitThermistorFailure(tbd),
Either solution would require new enumerationIs to be added to the
PrtAlertGroupTC object. I agree with Tom Hastings that a generic event =
code
would be the better solution. This will allow all Marker technologies
(current and future) to be addressed.
