WorkCentre 7425/7428/7435
System Administrator Guide 194
At the Computer
1. Open your Web browser and enter the TCP/IP address of the printer in the Address or Location
field. Press
Enter
. If the printer's CentreWare Internet Services (Web pages) begin to display on the
computer, you are communicating with the printer. If not, make sure that your Web browser is not
set to use a proxy server and repeat the procedure. If unsuccessful, perform the next step.
2. Verify that the computer has been assigned an IP address, subnet mask, and gateway address by
running a Command (DOS) prompt, typing ipconfig/all (Windows 2000/XP) and pressing Enter . If
any of the addresses are incorrect or missing, right click the
Network Neighborhood
icon (
My
Network Places in Windows 2000), and make sure that the TCP/IP protocol is installed and
properly configured for IP addressing. For XP, click
Start
/
My Network Places
, then right click in the
open window, select Properties , right click Local Area Connection , and then select Properties .
3. Run a Command (DOS) prompt on the computer and perform ping tests to verify successful packet
transmission first to the computer's NIC, then to the Gateway (if being used), then to the printer's
NIC. To run Ping Tests, at the Command (DOS) prompt, type:
ping xxx.xxx.xxx.xxx and press Enter .
Note that there is a space between the word ping and the first xxx. Let xxx.xxx.xxx.xxx first
represent the computer's IP address, then the IP address of the default gateway, and finally the IP
address of the printer. If successful, you will receive a reply such as: Reply from xxx.xxx.xxx.xxx:
bytes=32 time<10ms TTL=128. If you receive Time Out or 0 bytes received notifications, the
printer being pinged is incorrectly configured or malfunctioning.
4. If Web browser and Ping Tests are successful but you are still unable to print to the printer, verify
that the driver is using the correct LPR Port to print through. On Windows desktops, select Start ,
Settings
,
Printers
(
Start
/
Printers and Faxes
in XP), right click the printer's icon, and select
Properties . Select the Ports Tab (Windows 2000) and verify that the LPR Port being printed
through matches the IP Address of the printer. If the IP address does not match, you are printing
to the wrong device on the network. Either select the correct port from the displayed list, or use the
Add Port
button to create a new port with an IP Address matching that of your printer.
5. If the correct Port is being used by the driver but you are still unable to print, perform the following
procedure. In Windows 2000 or XP, verify that Print Services for UNIX are installed in the computer.
For more information see
TCP/IP Peer to Peer (LPR or Standard TCP/IP) Printing on page 13.
6. Note that access to this printer's Services can be restricted by Host IP addresses. As this feature
could cause communications to appear to fail in certain instances, see IP Filtering (IP Address
Restriction) on page 37.
7. To assure successful printing, make sure that the printer is configured to support the Page
Description Language (PDL) being used by your driver. To check the PDL being used by the driver,
print a test job to file. Open and view the job in a program such as Notepad. The PDL being used by
the driver will be displayed in the first few lines of Printer Language. Next, check the Page
Description Languages being supported by the printer's ports. For more information, see
Setting
PDL Emulations on page 30. The PDL being used by the driver, and the PDL supported by the Port
you are printing to, must match for successful printing to occur.
