LaserJet 9050n MiB Variable Issue

Question

I'm trying to find out what the MiB variable is for the paper level, I did some searching on the internet, found the list of MiB's for LJ9050mfp, and also LJ9000 Series, also the HP Common Lib, but when use the variable listed in each of these against my printer, I get either a no instance, or it error's out since the variable doesn't exist. I don't need the exact amount of paper, I would just like to see if it's empty or not, or even a percentage would be great. Here is a list of the variables I have tried: consumable-status-capacity-units SCALAR read-only INTEGER 1.3.6.1.4.1.11.2.3.9.4.2.1.4.1.10.1.4.0 consumable-status-total-capacity SCALAR read-only INTEGER ( 0..65535 ) 1.3.6.1.4.1.11.2.3.9.4.2.1.4.1.10.1.5.0 prtinputcapacityunit SCALAR read-only INTEGER 1.3.6.1.4.1.11.2.3.9.4.2.2.8.2.1.8.0 prtinputmaxcapacity SCALAR read-only INTEGER 1.3.6.1.4.1.11.2.3.9.4.2.2.8.2.1.9.0 prtinputcurrentlevel SCALAR read-only INTEGER 1.3.6.1.4.1.11.2.3.9.4.2.2.8.2.1.10.0 Someone please help!!! I would like to get this completed!!!!

Answer 1

The HP-LASERJET-COMMON-MIB defines several tray-specific objects which appear to define the media level in the specified tray; for example:
tray2-media-available OBJECT-TYPE
SYNTAX INTEGER(-1..100)
ACCESS read-only
STATUS optional
DESCRIPTION
"Returns a number that indicates how full the input tray
is. If the device can only detect empty / not empty the
device returns -1 for not empty and 0 for empty. If the
device can determine how full the tray is, the device
returns a percentage full from 0% to 100%
Additional information:
LaserJet 4V can only detect empty/not empty tray.
It returns -1 for not empty and 0 for empty."
::= { intray2 2 }
where:
intray2 OBJECT IDENTIFIER ::= { intrays 2 }
intrays OBJECT IDENTIFIER ::= { intray 3 }
intray OBJECT IDENTIFIER ::= { print-engine 3 }
print-engine OBJECT IDENTIFIER ::= { destination-subsystem 1 }
destination-subsystem OBJECT IDENTIFIER ::= { device 4 }
device OBJECT IDENTIFIER ::= { dm 1 }
dm OBJECT IDENTIFIER ::= { netdm 2 }
netdm OBJECT IDENTIFIER ::= { net-peripheral 4 }
net-peripheral OBJECT IDENTIFIER ::= { hpsystem 9 }
hpsystem OBJECT IDENTIFIER ::= { nm 3 }
nm OBJECT IDENTIFIER ::= { hp 2 }
hp OBJECT IDENTIFIER ::= { iso(1) org(3) dod(6) internet(1) private(4) enterprises(1) 11}
which would suggest that the OID for the tray_2 level is:
1.3.6.1.4.1.11.2.3.9.4.2.1.4.1.3.3.2.2
I've no idea whether or not this will provide you with what you need.
