Printer problems
Symptom: The printer does not work.
Actions: Verify that:
1. The printer is turned on and is online.
2. Paper is loaded correctly.
3. The printer signal cable is securely connected to the correct parallel, serial, or USB connector on the
computer.
Note: Non-IEEE-approved printer signal cables might cause unpredictable problems.
1. Any device drivers and other software that came with the printer are correctly installed.
2. You have assigned the printer port correctly in your operating system, application program, or BIOS
settings. For more information about BIOS settings, see Chapter 7 "Using the Setup Utility program"
on page 47.
If the problem persists, run the tests described in the documentation that comes with your printer. If you
cannot correct the problem, have the computer serviced. See Chapter 11 "Getting information, help,
and service" on page 75.
Serial connector problems
Use this information to troubleshoot the serial connector and devices attached to the serial connector.
Symptom: Serial connector cannot be accessed.
Actions:
• Ensure that the serial cable is securely connected to the serial connector on the computer and to the
serial device. If the serial device has its own power cord, ensure that it is attached to a properly grounded
electrical outlet.
• If the serial device has its own On/Off switch, ensure that it is in the On position.
• If the serial device has an Online switch, ensure that it is in the Online position.
• If the serial device is a printer, ensure that paper is loaded correctly.
• Ensure that any software supplied with the serial device is correctly installed. Refer to the documentation
for the serial-device option.
• Ensure that the serial-connector adapter, if you added one, is properly installed and firmly seated.
If these actions do not correct the problem, run the Lenovo Solution Center program. If you need technical
assistance, see Chapter 11 "Getting information, help, and service" on page 75.
