Web interface showing different toner level than SNMP

[der_eismann]

Hi everyone,

I was building a small status page for all our network printers using SNMP, however I noticed that the toner levels showed on the web interface and by SNMP are not the same.

Right now the printer page says 20%, but SNMP (OID: 1.3.6.1.2.1.43.11.1.1.9.1.1) says 25%. What's the reason for this? Do I need some special OIDs/MIBs? I never had a problem like this before.

Thanks,
Philipp

Hi 

I have the same issue but after a while, I notice that the % shown on the printer's page is a calculated value based in the tonner capacity

please see my SNMP results

C:\usr\bin>snmpwalk.exe -v2c -c public xx.xx.xx.xx 1.3.6.1.2.1.43.11.1.1
SNMPv2-SMI::mib-2.43.11.1.1.2.1.1 = INTEGER: 1
SNMPv2-SMI::mib-2.43.11.1.1.3.1.1 = INTEGER: 0
SNMPv2-SMI::mib-2.43.11.1.1.4.1.1 = INTEGER: 3
SNMPv2-SMI::mib-2.43.11.1.1.5.1.1 = INTEGER: 21
SNMPv2-SMI::mib-2.43.11.1.1.6.1.1 = STRING: "Black Cartridge HP Q7516A"
SNMPv2-SMI::mib-2.43.11.1.1.7.1.1 = INTEGER: 7
SNMPv2-SMI::mib-2.43.11.1.1.8.1.1 = INTEGER: 12000
SNMPv2-SMI::mib-2.43.11.1.1.9.1.1 = INTEGER: 8280

The printe page show 69%

now if you take 8280/12000 = 0.69
