Good afternoon!
The HPLJ M776 and HPLJ M775 MFPs return incorrect snmp values for the number of printed pages in color and black and white pages.
Following this page https://oidref.com/1.3.6.1.4.1.11.2.3.9.4.2.1.4.1.2, the OID here below should count the total printed pages, but those do not refer as the counter on the Usage Page on the web-interface of the printer.
1.3.6.1.4.1.11.2.3.9.4.2.1.4.1.2.6.0 - black
1.3.6.1.4.1.11.2.3.9.4.2.1.4.1.2.7.0 - color
But for other color MFPs, this oid works. I can't understand what is the reason.
