How do I check the toner level on the HP Neverstop Laser MFP 1200?

Check the toner level indicator on the front of the printer to determine when to add toner. The indicator shows states including Very Low (printer will not print until toner is added), Low, Fill (partly depleted), and Full (more toner cannot be added). When the Reload Status light next to the reload port glows white, toner can be added. (Page 3)
