Set up status alerts
Use the HP ToolboxFX to set up the printer so that it issues pop-up alerts to your computer when certain events occur. Events that trigger alerts include jams, low levels of toner in HP print cartridges, non-HP print cartridge in use, empty input trays, and specific error messages.
Select the pop-up format, the system tray icon format, desktop alert, or any combination for the alerts. The pop-up and desktop alerts only appear when the printer is printing from the computer on which you set up the alerts. Desktop alerts are only visible momentarily, and disappear automatically.
Change the Cartridge low threshold setting, which sets the toner level that causes a low toner alert, on the System setup page.
You must click Apply before your changes take effect.
