Web Browser/HTTP Problem
In some cases you may not be able to browse the printer Web page
simply because the NIC HTTP may be turned off.
If you cannot ping the NIC IP address, make sure the IP address,
subnet mask, and default gateway are set correctly by checking the
ETHERNET PARAMS menu from the control panel. See the
User's
Manual for configuration menu information.
If you can ping the NIC IP address but cannot access the Web
pages, perform the following procedure to verify the NIC HTTP is
turned on:
1. Telnet into the NIC and log in as root with no password.
2. At the system prompt, enter the following commands:
config http on
save
reset
3. After approximately 5 minutes, point your browser to the NIC IP
address. The printer Web pages should now be accessible.
If you still experience difficulty accessing or browsing the printer,
contact the Customer Solutions Center for further assistance.
