Image Transfer Failures Troubleshoot image transfer failures only after verifying that the I/O configuration on the computer is correct and that the software performs adequately. Also confirm that the parallel cables being used are IEEE-1284 compliant parallel cables. If the Companion scans documents correctly, but the scanned image will not transfer to the printer or to the computer, initialize NVRAM (see Chapter 3) and try again to scan. If scanned images still will not transfer, replace the control board. Image Quality Problems Image quality problems come in several varieties:
the image is too dark or too light, the image contains dark or light spots, or the image contains vertical or horizontal lines. Set the software to the appropriate resolution. Note It takes more time to scan at higher resolutions. Clean the image sensor and scan roller. Calibrate the Companion (see Chapter 3). If image quality problems are not solved, 1 Replace the image sensor. 2 Replace the control board. 3 Replace the scan roller. 4-6 Troubleshooting EN
