"Configuring a Port and Installing the Printer Driver"

Cause 4: The computer is not configured properly.

Solution: Use the following procedure to specify the printer as the default printer.
  1. Open the [Printers and Faxes] or [Printers] folder.
    • Windows Vista: [Start] → [Control Panel] → [Printers]
    • Windows XP Professional and Server 2003: [Start] → [Printers and Faxes]
    • Windows XP Home Edition: [Start] → [Control Panel] → [Printers and Other Hardware] → [Printers and Faxes]
    • Windows 2000: [Start] → [Settings] → [Printers]
  2. Select [Canon LBP5050] → click [File] → [Set as Default Printer].

All of the indicators on the printer network board are off.
Cause 1: The Ethernet cable is not connected properly or is damaged.

Solution 1: Disconnect the Ethernet cable and then reconnect it.

Solution 2: Replace the Ethernet cable.

Cause 2: The Ethernet cable is connected to the UP-LINK (cascade) port on the hub.

Solution 1: Connect the Ethernet cable to the port on the hub with an "X" mark.

Solution 2: If the hub has an UP-LINK (cascade) switch, switch to the "X" side.

Cause 3: A cross-type Ethernet cable is used.

Solution 1: Use a straight-type Ethernet cable.

Solution 2: Connect the cross-type Ethernet cable to the UP-LINK (cascade) port on the hub. If the hub has an UP-LINK (cascade) switch, switch to the "=" side.
NOTE
Cross-type Ethernet cable

Use this type of cable when connecting the printer directly to a computer.
Cause 4: Cannot communicate with the hub.

Solution: Make sure that the hub is on.
The ERR indicator on the printer network board is on.
Cause: The Ethernet cable is not connected properly or is damaged.

Solution 1: Make sure that the Ethernet cable is connected properly.

Solution 2: Replace the Ethernet cable and check if it is damaged.

Solution 3: If the ERR indicator still comes on after performing the above solutions, contact your local authorized Canon dealer.
The ERR indicator on the printer network board blinks at an interval of four times.
Cause: The network board was reset (the printer was turned on while pressing the reset button on the network board), resetting the network board to the default settings.

Solution: Turn off the printer, wait at least 10 seconds, and then turn on the printer.

The ERR indicator on the network board is constantly blinking.
Cause: The network board is not operating properly.

Solution: Contact your local authorized Canon dealer to request repair.

The printer became unable to print from the network suddenly.
Cause: The printer was turned off or on when used in a DHCP environment, thereby changing the IP address of the printer.

Solution: Contact your network administrator, and then perform either of the following operations.
  • Set the DNS Dynamic Update function.
    "Displaying the Network Settings"
  • Configure the DHCP or other setting so that the same IP address is always assigned to the printer when the printer is started.
