Your scanner probably just needs a good cleaning. You can use a dry Q-tip on the scan lamp and mirrors, and the motor that moves the scan bar has a disk with black bars on it that control the scanner movement, you get bars when the motor misses bars on the disk. Try scanning a typed page and see if the characters line up properly. No lube is used on the scanner rails, but you can use alcohol to clean them as well for even and smooth travel. After the inside and underside of the glass is clean you use canned air to remove any fibers from your cloth or Q-tip that could be left inside.
