A.9 Notes and Restrictions 395
• Specifying the URL with FQDN (IPv4 and IPv6)
Before creating the self-signed certificate, you need to specify the device host name and
domain name correctly.
Example: When the FQDN is csw.ipv6.domain.local, “csw” is the host name and
“ipv6.domain.local” is the domain name.
• Specifying the URL with an IPv4 address
Import of a self-signed certificate is not required in the IPv4 mode or dual mode.
• Specifying the URL with an IPv6 address
Secure IPP (IPP-S) communication is not supported.
• The following functions do not support IPv6. Run using IPv4. IPv6 does not support the
following protocols:
• UPnP Discovery
• In the cases below, the user may not be able to cancel or check the status (lpq) of print jobs
requested using LPD when the address of a single machine cannot be determined.
• When IPv4 and IPv6 are in operation simultaneously on the same host
• When multiple IPv6 addresses are in operation simultaneously on the same host
• The IPv6 address may not be entered correctly in the job log. Run using IPv4.
• With DocuShare or some other external access service, operation is improper when an IPv6
address is specified as the connection destination URL. In the IPv6 environment, enable the
DNS server and specify the destination URL using an FQDN.
• IPv6-in-IPv4-tunneling in the machine itself is not supported.
Important
• If [TCP/IP Setting] > [IP Mode] is set to [IPv6], the IPv6-inIPv4-tunneling cannot be performed.
• If more than one router exist in the same subnet, a communication error may occur.
• In a dual stack environment, some services may cause performance problems depending on the network settings
(for example, when you attempt to set the machine to prioritize IPv6 in an environment where the Web server is
started with IPv4).
Notes and Restrictions on the Cloning Feature
The Cloning feature copies settings from one printer and imports them to another printer.
You can copy these settings to a file and import them with CentreWare Internet Services under
the [Properties] tab > [General Setup] > [Cloning].
This section lists the notes and restrictions that apply when using the Cloning feature.
• This feature does not copy and import all printer settings. It mainly copies and imports settings
on the [Properties] tab in CentreWare Internet Services.
