SNMP not showing toner levels

[Groverboy]

We have four of this printer model in our organization: HP Color LaserJet Pro MFP 4301, and none of them send/show ink/toner levels via SNMP to PaperCut or other utilities that our toner vendor uses. This is the only HP model with this problem. Has anyone else seen this and if so, do you have a solution?

You weren't able to find them at OID=mib-2.43.11.1.1.9.1.x (where x=1 to 4: 1=M, 2=C, 3=Y, and 4=K)?

I am polling those MIBs in to a PI Data archive (and they're the same that an old Color Office Jet Pro used) with no major hassles.
