Back to TOC If the scanner or software is not working but no message appears, look for the cause and solution in this section. The scanned image might not have been saved as a file. If you send an image directly to a destination, the scanned image is not saved on the computer. Use the FILE button on the scanner, or save files using the HP PrecisionScan Pro software. The scanner lamp stays on as long as the software is running and might stay on for a while after the software is closed. This is normal, and the lamp will turn off on its own. You might have saved the file in a format the other program cannot use. Save the file in a different format the program can use. Look in the File Open or Import command for the program to see which file types it supports. Troubleshooting usage and maintaining 81 One or more of these issues might be causing the problem: The scanner was not installed properly. The SCSI card or drivers were not installed properly. The SCSI card or cable is not compatible with the scanner. The scanner address is not properly set, or multiple SCSI devices are set to the same address. If the scanner is emitting a grinding sound, the scanner is locked. See "Checking the basics" on page 79 and the Setup and Support Guide. If the scanner has not been used for a while, the scanner lamp has turned itself off. Wait for a few seconds for scanning to begin. A cable might be loose. Check that the USB or SCSI cable is securely connected. Check which program is set to open when you press E-MAIL, FAX, or EDIT TEXT on the scanner. See "Changing settings for buttons" on page 24.
