I created this template for my office printer OKI ES8461 MFP.Not sure if it works with any other models.Let us know in comments.
A template to check supplies on OKIDATA printers (you´ll need the OKIDATA MIB).It provides items and triggers for toner, drum, fuser and belt levels as well as a simple paper count.I´ve been using it with an OKI C5950 and an OKI C610 printer.You´ll need to add a ´zabbix´ snmp read community on your printer (from the Admin webpage choose Network->SNMP->Settings->Step2) or change the community to ´public´ within the template.Triggers will be activated at 11% for toner and 10% for drums, belt and fuser unit, which should be ample time to restack on supplies unless you´re really printing loads of pages.EDIT: 2017-06-01 Updated this for adjusted trigger levels on toner and drums as the chosen ones were too low.
