.
Can you print a configuration page?
If you cannot print a configuration page, there maybe a
machine malfunction. Contact your sales or service rep-
resentative.
See for printing a configuration page.
Is the interface cable connected se-
curely to the machine and comput-
er?
Connect the interface cable securely. If it has a fastener,
fasten that too.
Are you using the correct interface
cable?
The type of interface cable you should use depends on
the computer. Be sure to use the correct one. If the cable
is damaged or worn, replace it.
Is the signal status satisfactory when
using wireless LAN ?
When using wireless LAN in ad hoc mode or 802.11b ad
hoc mode, move the machine to a location where radio
waves can pass or remove objects that might cause in-
terference.
When using wireless LAN in infrastructure mode, check
signal status using the

menu on the control
panel. If signal quality is poor, move the machine to a lo-
cation where radio waves can pass or remove objects
that might cause interference.
Is the Call-light blinking or lit?
If a Call-light is installed, it notifies you of any errors that
occur during printing via its light. Check if the Call-light is
blinking or lit, and solve any errors. See
p.95 “Call-light
Lit or Blinking”
