Normally, after I fix an issue and I want instant confirmation in Lansweeper, I run select the device and "Rescan Asset" on that asset. As an example : If I replace a printer toner cartridge because it's at 1%, select that printer in Lansweeper and then select to "Rescan asset". It will scan and then in a couple of minutes the report or printer status will show 100% toner.
You do not have to wait for a "scheduled" scan you can scan anything you want at any time. A single device a group of devices, or any scanning target group.
