Step 4: Notify the Network Users
Users connected to the network need to know the policy in effect and the supporting information
outlined in the following table.
POLICY ADDITIONAL INFORMATION
1) Simple addressing The IP address of the copier(s).
2) Regular DHCP The IP address of the copier(s).
3) Full DHCP The Hostname of the copier(s).
4) Exception DHCP The Hostname of the copier(s).
Troubleshooting
• Network Administrators should understand the architecture and use caution when changing
network parameters associated with network scanning. If problems occur after changing
your network policy or server settings, it is recommended that all scanners and PCs running
the Network Scanner Tool be reconfigured from scratch.
• While the Network Scanner Tool tries to automatically determine the proper network
parameters, sometimes you will need to assist it with information about the advanced
architecture. In particular, if the Auto Detect feature cannot find the scanner you want to
use, you will have to manually enter the address. This can occur if the operating system is
Windows 95 (without Winsock 2) or the network equipment filters UDP Broadcast packets
between your computer and the scanner. To manually set the scanner IP address, refer to the
Adding a New Scanner section in Chapter 4.
Note: Auto Detect does not search beyond the local subnet of the network. Scanner
addresses outside the local subnet must be manually entered.
• If UDP packets (not broadcast) are filtered between the PC and the scanner, the
configuration step for the Network Scanner Tool will fail. TCP/IP and UDP/IP are required
to use the Scan to Desktop function.
Technical Information
During the automated setup process, the Network Scanner Tool determines the addressing
methods used by scanners and PCs using the following logic.
1. If the address of the scanner is in the DNS table, “Host Name” is used for the “Scanner
Setting”.
2. If the address of DNS server on the scanner web page is not blank, and the current PC is
listed in the DNS table, “Host Name” is used for the “PC Setting”.
