HP devices can provide extended configuration items using proprietary objects.
Reports
Third-party support includes only reports that indicate Device Inventory or Engine Cycle Counts. HP
devices include reports that make use of the various supported page count values such as Accessories
Inventory (capabilities), Supplies Utilization (marker supply info), Device Utilization (page counters),
and Peak Usage (hourly page counters).
TROUBLESHOOTING
Trying to determine why a particular third-party device supports what it does usually boils down to the
ability of the device to answer the queries HP Web Jetadmin sends. HP Web Jetadmin is at the mercy
of the device to answer industry-standard queries. Some devices support more gauges than others
and it cannot be assumed that all devices from a particular vendor will support the same features. For
example, one Xerox model may support the control panel display while another Xerox model does
not. Common explanations for why particular items may not appear for devices include:
Issue: A gauge may be present for a
consumable but the gauge is hashed out
instead of containing a remaining
percentage.
Reason: If a device answers
prtMarkerSuppliesDescription correctly,
the gauge is present, since HP Web
Jetadmin knows the consumable exists.
However, if the device cannot answer
either prtMarkerSuppliesMaxCapacity or
prtMarkerSuppliesLevel correctly, the
percentage cannot be calculated and
HP Web Jetadmin displays hashes
instead to indicate an “unknown” level.
Issue: A paper tray gauge does not
indicate a remaining percentage.
Reason: If a device answers the
prtInputType query to indicate a tray is
present, the device may respond to the
prtInputMaxCapacity and
prtInputCurrentLevel queries with either
valid values or indicate that at least one
sheet remains. If valid values are
returned, a calculation is presented. If
valid values are not provided, HP Web
Jetadmin displays either “empty” or “not empty” depending on whether the device indicates at least
one sheet remains.
Issue: Control Panel displays “Not Supported” or “Unknown”.
Reason: “Not Supported” indicates the device did not respond to the prtConsoleDisplayBufferText
object. “Unknown” may indicate that the device recognizes the prtConsoleDisplayBufferText object
but did not respond with any text.
