DHCP (Dynamic Host Configuration Protocol) is a system in which UNIX and Windows NT servers can allocate IP addresses dynamically. The printer is a DHCP client; when the printer is reset, it receives an IP address from the DHCP server.

Enabling DHCP on the printer

Make sure that the printer's DHCP protocol is enabled. You can do this from the front panel; see Disabling and enabling protocols: Phaser 750 front panel.

Installing the DHCP server

1. In Control Panel:Network, select Add Software.
2. Select TCP/IP components.
3. In the second window that is displayed, select DHCP server.

Setting up a DHCP server

1. Access your DHCP management utility:
• Windows NT 4.x. Click Start; select Programs, then Administrative Tools (Common). Select DHCP Manager.
• Windows NT 3.5x. Go to the Network Administration group and select DHCP Manager.
2. Configure DHCP with a scope; a scope is a range of IP addresses available for allocation to DHCP clients. For example, the scope could be the IP addresses 192.2.194.101 through 192.2.194.254.

Defining a scope in Windows NT 4.x

1. Click Start, Programs, Administrative Tools, DHCP Manager.
2. Double-click Local Machine.
3. Click Scope, Create.
4. Enter the IP information to define the scope.

Defining a scope in Windows NT 3.5.x

1. Open the Network Administration group.
2. Double-click DHCP Manager.
3. Double-click Local Machine.
4. Click Scope, Create.
5. Enter the IP information to define the scope.
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 to renew its lease of the 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:
1. In Control Panel:Services, scroll to DHCP Server.
2. Click Stop; click Start.
3. Click Close.
6. Reset the printer. The printer receives its IP address from the server. Print a Configuration Page to obtain the IP address. See The printer's Configuration Page.
7. Using Add Printer Wizard (Windows NT 4.0) or Print Manager (Windows NT 3.5x), verify that a Windows NT printer port refers to the printer's IP address or DNS name.
8. Configure the printer's DHCP client software.
