Please bear with me as I've never seen your printer model but I'll try my best to advise you. There are a few ways you can normally achieve this, if your printer has an LCD panel and menu, normally there will be a settings option that would allow you to print off a status page that would tell you how much toner is left. (you can find the instructions manual and how to do this on the
manualslib.com website here).
Alternatively, you can use your computer to navigate to printer preferences and depending on the printer software, you will sometimes see a display of the toner left. To get to this on a Windows 10 PC, click start > click the cog > Devices > Printers and scanners > click your printer name > manage > preferences. The dialogue box will pop up and there will be tabs with different options. Sometimes the option to see what toner is left is found there. For PCs that aren't Windows 10, go through the control panel in the start menu and printers & devices (the steps are mostly the same).
