Images with horizontal black lines

There are a number of potential causes for images that are streaked with horizontal black lines. The following pages will discuss different solutions for eliminating the problem. It is suggested that you implement each of the steps, in the order presented, one step at a time and not proceed with the following steps once the problem has been resolved. After each step, disconnect both the power and USB cables from the back of the scanner and reboot your computer before resuming your normal activities.

1. Standby / Sleep / Hibernation mode interference. Eliminate Standby / Sleep / Hibernation mode. See the following pages. 

a. Power options for XP users:

From the Control Panel, edit the power options. On the power schemes tab, make sure the monitor, hard disks, and system standby are set to never. On the hibernate tab, if present, make sure the enable hibernation check box is not checked. 

In Device Manager, under the Universal Serial Bus controllers node, open the properties for each entry and make sure the check box to allow the computer to turn the device off is unchecked

b. Power options for Windows 7 users: From the Control Panel, edit the power options. Choose Change Plan Settings for the active power plan. Make sure the monitor and hard disks are set to never.
