Has anyone here been able to retrieve the toner levels from a Brother MFC-L8690CDW printer using SNMP? I've tried accessing the default OIDs, but the toner values returned seem off (-3 for the level and -2 for max capacity). If you've discovered any working OIDs or have alternative methods for checking toner levels, your insights would be greatly appreciated! Cheers!

Have you tried running an snmpwalk command? It could give you a better view of what’s available on the device.
I haven't worked specifically with that model, but I've noticed that some printers don’t directly report toner levels. In the past, I've managed to get the readings by using the maximum toner level and dividing it by the used toner level, then multiplying the result by 100 to get a percentage. If you do a quick search or ask an AI tool for those OIDs, it might help you out! And do share your findings if you discover something—it could be helpful down the line!
I’m familiar with that method too. I’ve already checked online for those OIDs and even asked AI, but no luck so far. I was hoping someone might have another method, like web monitoring or something similar.

Yeah, I’ve done that a few times already, but I still didn't find any useful or reliable data.
