Cause
Network communication is
not available because the
machine's IP address could
not be obtained from the
host name. If only "IPv6" is
set to [Active], the IPv6
address might not be
obtained.
Cause
The scanning glass or guide
plate of the ADF is dirty.
There is a possibility that the
PDF version is not supported
by the browser's PDF viewer
or an unsupported
encryption level is specified.
The output tray is full.
Solution
• Check whether the machine's host
name is specified in the Network
Connection Tool. For the WIA
driver, check the [Network
Connection] tab in the properties.
• Use Web Image Monitor to set
"LLMNR" of "IPv6" to [Active].
Solution
Clean the scanning glass or guide
plate. See page 534 "Maintaining
Your Machine".
With this machine's browser PDF files
other than those whose versions and

• Remove paper from the output
tray to resume printing. If paper is

resume printing.
