Troubleshooting parallel port issues - ThinkPad
|
 |
|
Some of these steps may not apply to your computer. Test the parallel port after performing each step.
- Verify the cable is connected firmly to the ThinkPad system parallel port by detaching and reattaching the connector.
- Verify the external device cable meets the manufacturer requirements.
For example, most printers require an IEEE-1284 cable that is no longer than 6 feet in length.
-
Verify the parallel port is enabled and configured properly in the ThinkPad Configuration utility.
- Click Start, select Programs, select ThinkPad, select ThinkPad Utilities, and then click ThinkPad Configuration.
- Click the Parallel Port icon. The Parallel port window will appear.
- Select Enabled next to parallel port, and then click Apply.
- Select the appropriate Operating mode for your external device. The options are Bi-direction, ECP, EPP, and Uni-direction.
-
Click the Allocated Resources tab to view the current resources allocated to the parallel port.
Notes:
- The default setting for most ThinkPad systems is Input/Output range 03BC - 03BE.
-
If the current resources are not compatible with your external device, then click the Device Properties button on the General tab to change the settings in the operating system. The Printer port properties window will be displayed.
- Select the Resources tab.
- Click Use automatic settings to remove the check from the check box.
- Select Basic configuration 001 (for Input/Output range 0378 - 037F and IRQ 7 which is most common) from the pull down list in the Setting based on: box. Select a different basic configuration number to select other appropriate resources.
- Click OK and then click Yes to continue.
-
Test the parallel port for errors
- Run the PC Doctor diagnostics for all current ThinkPad A, G, R, T, and X series systems. PC Doctor for DOS is available by pressing the F11 key or the Access IBM button during startup to access the predesktop menu area. If these methods are not available for your system, then PC Doctor for DOS may be downloaded. This DOS version requires two or more floppy diskettes depending on the ThinkPad system.
-
Run the test in Easy Setup for ThinkPad 600, 600E, 770, 770E/ED, 770X, and 770Z systems.
- Press and hold the F1 key, then turn on the computer. Hold the F1 key until the Easy-Setup menu appears. If a password prompt appears, type the correct password.
- Select Test.
- Click the Parallel symbol to run the test. The results will be displayed as blue OK or red error codes.
- If these steps have not solved your problem, please refer to "Need more help?"

Note: Most ThinkPad systems do not have a parallel port. However, a parallel port can be accessed when the ThinkPad is connected to a docking station or UltraBase dock.
