Ricoh C4500 shows model instead of system name

Ok, added numeric oid (.1.3.6.1.4.1.367.3.2.1.6.1.1.7.1) as sysname in r12113.

This is exactly what device report in sysName OID.
(we use self SNMP HEX decoding for prevent UTF8 issues, it doesn't affect your question).

Attach snmpdump as Observium Bot requested, I will try to find different OID with correct sysname value.

I'm gussing it has somthing to do with this during the discovery or polling

sysUpTime.0 = 49:5:09:50.00
sysLocation.0 = "4C 6F 63 61 6C 20 41 64 6D 69 6E 69 73 74 72 61 74 69 66 "
sysContact.0 = ""
sysName.0 = "49 4D 20 43 34 35 30 30 "
]
SNMP Hex string converted..
   HEX: 4C 6F 63 61 6C 20 41 64 6D 69 6E 69 73 74 72 61 74 69 66
STRING: Local Administratif

SNMP Hex string converted..
   HEX: 49 4D 20 43 34 35 30 30
STRING: IM C4500

The sysName.0, .1.3.6.1.2.1.1.5.0 or .1.3.6.1.4.1.367.3.2.1.1.1.1.0 all answer the model number instead of the hostname so I'm guessing it has to do with either the MIB being out of date or an issue with the printer's firmware itself

snmpwalk -v2c -c ***-t 3 -Cc --hexOutputLength=0 -ObentxU 172.16.119.65 sysName.0
.1.3.6.1.2.1.1.5.0 = STRING: IM C4500

snmpwalk -v2c -c ***-t 3 -Cc --hexOutputLength=0 -ObentxU 172.16.119.65  .1.3.6.1.4.1.367.3.2.1.1.1.1.0
.1.3.6.1.4.1.367.3.2.1.1.1.1.0 = Hex-STRING: 49 4D 20 43 34 35 30 30

Edit :The hostname's hex OID seems to be on .1.3.6.1.4.1.367.3.2.1.6.1.1.7.1 *

snmpwalk -v2c -c *** -t 3 -Cc --hexOutputLength=0 -ObentxU 172.16.119.65 .1.3.6.1.4.1.367.3.2.1.6.1.1.7.1
.1.3.6.1.4.1.367.3.2.1.6.1.1.7.1 = Hex-STRING: 50 43 4D 49 4D 50 30 30 31

General questions and device support can be discussed in our Discord channel, click here to join.

Please make and attach additional information about the device:

• full snmp dump from device:

  snmpwalk -v2c -c <community> -t 3 -Cc --hexOutputLength=0 -ObentxU <hostname> .1 > myagent.snmpwalk

  snmpwalk -v2c -c <community> -t 3 -Cc --hexOutputLength=0 -ObentxU <hostname> .1.3.6.1.4.1 >> myagent.snmpwalk

  If device not support SNMP version 2c, replace -v2c with -v1.

• If you have problems with discovery or poller processes, please do and attach these debugs:

  ./discovery.php -d -h <device>

  ./poller.php -d -h <device>

• additionally attach device and/or vendor specific MIB files
