SNMPv3 authentication and encryption has three levels of support:
No authentication and no encryption

Certificate Authentication—Allows any hosts or subnet of hosts to authenticate for IPSec. 
Each host must have a public/private key pair. Validate Peer Certificate is enabled by default, 
requiring each host to have a signed certificate. The certificate authority certificate must be 
installed. Each host must have its identifier in the Subject Alternate Name of the signed 
cer tificate.
Note:After an MFP is configured for IPSec with a host, IPSec is required for any IP 
communication to take place....

Disabling ports and protocols
The TCP and UDP ports can be configured to one of three modes or values:
Disabled—Never allows network connections to this port
Secure and Unsecure—Allows the port to remain open, even in Secure mode
Unsecured Only—Allows the port to only open when the MFP is not in Secure mode
Note:A password must be set to enable Secure mode. Once enabled, only the ports set 
to Secure and Unsecure will be open.
To configure the mode for TCP and UDP ports from the EWS:

to the MFP.
Note:The Restricted Server List only restricts TCP traffic; it does not affect UDP traffic. 
The Restricted Server List supports up to ten host addresses or ten network 
addresses.
To configure the Restricted Server List from the EWS of the MFP:

Clearing jams
By carefully selecting print media and loading it properly, you should be able to avoid most paper 
jams. For more information on avoiding paper jams, see Avoiding jams. If jams do occur, follow the 
steps outlined in this section.
To resolve the paper jam messages, you must clear the entire paper path, and then touch Continue 
to clear the message and resume printing. The MFP prints a new copy of the page that jammed if 
Jam Recovery is set to On or Auto; however, the Auto setting...

Access doors and trays
The following illustration shows the path that print media travels through the MFP. The path varies 
depending on the input source (trays, multipurpose feeder, envelope feeder) you are using.
The numbers in following the illustration indicate the numbers that can appear on the control panel 
and designate the general area of a paper jam.
CAUTION:Floor-mounted configurations require additional furniture for 
stability. You must use either a printer stand or printer base if...

Understanding jam messages
The following table lists the jam messages that can occur and the action necessary to clear the 
message. The jam message indicates the area where the jam occurred. However, it is best to clear 
the entire paper path to ensure you have cleared all possible jams.
Clearing jams
Paper jams can occur in three areas: the front of the MFP, inside the MFP, and at the rear of the MFP. 
Jams in the front of the MFP occur in the input options or the duplex tray. Jams inside the MFP...
