Setting the Printer’s IP Addressing Parameters 8
Setup Guide 63
3. Define the lease. A lease is a pre-determined time that the printer holds
the IP address. When the lease time expires, the printer queries the
DHCP server again for another IP address. It is recommended that you
set the lease to Unlimited.
4. Define a name for the scope. You are prompted to activate the newly
created scope; answer Yes.
5. Restart the DHCP server:
a. In Control Panel:Services, scroll to DHCP Server.
b. Click Stop; click Start.
c. Click Close.
6. Turn on the printer. The printer receives its IP address from the server.
Print a Configuration Page to obtain the IP address (“Printing a
Configuration Page” on page 2).
7. Set up Print Manager to point to the printer’s IP address. See
Chapter 7, “Windows NT” for more information.
8. Configure the printer’s DHCP client software.
DHCP transactions
■ On power up or reset, the printer sends a DHCP discover packet,
indicating its Ethernet address and requesting an IP address.
■ The DHCP server responds to the discover packet with a DHCP offer
packet, which contains an IP address from within the assigned scope
and the assigned lease.
■ The printer examines the DHCP offer packet and decides whether to
accept the lease. The printer sends a request packet, accepting the IP
address and the lease.
■ The DHCP server sends an acknowledgment packet to the printer, which
completes the transaction.
N O T E
There can be multiple DHCP servers on the same network, each defining its
own scopes and leases; the printer selects the offer with the longest lease.
