150% toner level reported

please excuse my manners... I forgot about the debug - http://pastebin.com/mqU9P3sb

the pages have now updated to alll say 1% which I know isnt correct because the webpages of the machines say ' 60% unknown 40% 50% '

but its defo getting closer

Simon, debug for discovery/poller very helpful:

./discovery.php -d -m toner -h your_printer

./poller.php -d -m toner -h your_printer

that fix hasnt worked sadly
its now showing no toners and very weird text blobs?

also I have found some interesting Ricoh Public and Private MIBs if anyone wants a look at them - http://anywhere.support/ricohmib

and from what ive read in them its 1.3.6.1.4.1.367.3.2.1.2.24.1.* you need to be looking at for the Ricohs

Quick fix added in r6194.

is the any update on this issue at all?
our 3 ricoh printers are still showing 150%
Ricoh MP C4000, C5000, C2550

This doesn't look like a bug, but instead is the result of the printer not actually reporting accurate toner values via SNMP.

From the Printer-MIB:

prtMarkerSuppliesMaxCapacity

Registration: 1.3.6.1.2.1.43.11.1.1.8
Access: read-write
Reference: None
Description:

The maximum capacity of this supply container/receptacle
expressed in SupplyUnit. If this supply
container/receptacle can reliably sense this value, the
value is sensed by the printer and is read-only;
otherwise, the value may be written (by a Remote Contol
Panel or a Management Application). The value (-1) means
other and specifically indicates that the sub-unit places
no restrictions on this parameter. The value (-2) means
unknown.

prtMarkerSuppliesLevel

Registration: 1.3.6.1.2.1.43.11.1.1.9
Access: read-write
Reference: None
Description:

The current level if this supply is a container; the
remaining space if this supply is a receptacle. If this
supply container/receptacle can reliably sense this
value, the value is sensed by the printer and is
read-only; otherwise, the value may be written (by a
Remote Contol Panel or a Management Application). The
value (-1) means other and specifically indicates that
the sub-unit places no restrictions on this parameter.
The value (-2) means unknown. A value of (-3) means that the
printer knows that there is some supply/remaining space,
respectively.

So if the printer only reports whether there is some toner left, but not how much, it returns -3. It also will return a -2 for the capacity.

The code for calculating the toner takes the current level (in this case -3), divides it by the capacity (-2), and multiplies by 100. This will be 150 everytime, so long as there is any toner left. To make this work "correctly", the printer manufacturers would have to modify their code to report the specific values for the level and capacity via SNMP.

Hi,

I also noticed this bug in CE 0.14.4.5229 reporting 150% of toner in Brother printers:

• DCP8085
• HL-5350DN
• HL-3040CN (150% level on all color toners)

Regards,

SNMPwalk of RICOH Aficio MP C5000 with low yellow and cyan toner, displaying as 150% toner in observium build 5311.

Just chiming in to say I'm experiencing the same behavior. Printer device is a Brother HL-3170CDW, this issue is present on Brother firmware 1.14 and 1.16 when running Observium Community versions 13.10 and 14.4p1.
