Scan-quality problems Prevent problems The following are a few simple steps you can take to improve copy and scan quality. ● Use the flatbed scanner, rather than the automatic document feeder (ADF) input tray, to scan. ● Use high-quality originals. ● Load the media correctly. If the media is loaded incorrectly, it might skew, which causes unclear images. ● Adjust the software settings according to how you plan to use the scanned page. ● If your product frequently feeds more than one page at a time, you might need to replace the separation pad. ● Use or make a carrier sheet to protect your originals.
