Hi, im using librenms mostly to check toner levels. I have about 220printers. At 158 ricoh printers (mostly mp201 mp 301) toner level is constant at 50%. There is no problem with OKI or hp, lexmark devices. Can you give me some advices how to fix it?
I tried to monitor ink level on my own on Brother devices. Same symptoms.
I’ve found my Brother reports the ink levels @ such OIDs:
.1.3.6.1.2.1.43.11.1.1.9.1.1 = INTEGER: -3 (Black)
.1.3.6.1.2.1.43.11.1.1.9.1.2 = INTEGER: -3 (Yellow )
.1.3.6.1.2.1.43.11.1.1.9.1.3 = INTEGER: -3 (Cyan)
.1.3.6.1.2.1.43.11.1.1.9.1.4 = INTEGER: -3 (Magenta)
.1.3.6.1.2.1.43.11.1.1.9.1.5 = INTEGER: -3 (Absorber)
It does not present the values as percentage. It shows it as an “quarter-parts”. -3 is “below 50%” for what I noticed @ my device.
I hope you’ll find useful solution for this.
I’ve got the same problem with Ricoh printers and did a bit of poking around. All the supplies in the PrinterMIB supplies OIDs are reporting -3 regardless of current supply level. The OID here contains correct supply data for all of the Ricoh printers I’ve tested here, it’s just not being used by LibreNMS.
