System Contact column is considered out-of-date after 24 hours because the contact does not change
frequently. The Model column is never considered out-of-date because the device model never changes.
If you use HP Web Jetadmin to update the System Contact value for a device, the 24-hour polling threshold is
not valid. HP Web Jetadmin immediately updates the System Contact column in the device lists. If you use
another mechanism, such as HP Embedded Web Server, to change the System Contact value, HP Web Jetadmin
does not display the updated value in the device lists for 24 hours. However, you can refresh the information in
the device lists at any time to reect the current values for the devices. For instructions, see Refresh device
selection in Top Menu Bar on page 32.
Use the following steps:
1. On the top menu bar, access Tools > Options > Device Management > Device Polling > Background
2. Congure the desired settings:
Polling interval: Specify the number of seconds during which HP Web Jetadmin sends device requests
to the network. The default is 2.
Time between polling intervals: Specify the number of seconds that HP Web Jetadmin remains idle
between polling intervals. The default is 10.
Number of devices per poll: Specify the number of devices that HP Web Jetadmin can query
concurrently. The default is 2.
HP Web Jetadmin sends device requests for the specied number of devices to the network in a poll
burst and waits for the responses. When HP Web Jetadmin receives the response packets, it sends
another burst of device requests. HP Web Jetadmin continues to send device requests until the
specied polling interval expires, and then waits until the specied number of devices per poll is
satised before sending new device requests.
3. Click the Apply button.
To reset all of the values to the defaults, click the Reset to Default Values button.
