TCP/IP Access Problem
If you can
ping
the printer from a workstation, but you cannot Web
browse (Smart Ethernet Interface), Telnet, or print to the printer
through the Ethernet Interface, there may be an incorrect entry in
the TCP access list. So the workstation can use the Ethernet
Interface, one of two things must happen.
•
the TCP list must have an entry added to grant access to this
workstation, or
•
all entries must be deleted from the TCP list to grant all
workstations/hosts access to the above TCP services.
To view the current access list, print the E-NET Test Page following
the steps in “Ethernet Interface Verification” on page 37. When the
page prints, look under the “TCP ACCESS TABLE” section for the
TCP access list entries.
To add/delete a TCP access list entry, refer to “TCP Access Lists”
on page 287.
NOTE: When the following procedure is used, the TCP access list
will be cleared, but all IP addresses will need to be entered
again after the procedure is complete.
To reset all TCP/IP values to the factory defaults when access is
impossible:
1. Obtain a printer configuration printout using the control panel.
See the User's Manual for configuration menu information.
2. Power off the printer.
3. On the Ethernet Interface, place SWITCH 1in the down
position.
4. Power on the printer and wait for the ONLINE state.
5. On the Ethernet Interface, place SWITCH 1in the up position.
6. From a workstation attached to this network segment, create
an ARP entry. The Ethernet Interface IP address and hardware
or MAC address are needed. At the workstation enter:
arp -s <ipaddress> <MACaddress>
ping <ipaddress>
