The machine will not scan a document.
Q Did you connect the power cord to the machine just now?
A Wait for a while. After connecting the power cord, the machine cannot scan
documents immediately.
Q Is the document loaded correctly?

(See “Loading Documents in the ADF,” on p. 3-4.)
A Make sure the ADF is closed.
Q Is the USB cable connected securely?
A Check that the USB cable is connected securely to the machine and your
computer. Disconnect the USB cable, and reconnect it correctly after a while.
Scanned images are dirty.
Q Is the platen glass or the platen glass cover clean?
A Clean the platen glass or the platen glass cover. (See “Cleaning the Scanning
Area,” on p. 8-2.)
White streaks appear on the left side of the image.
Q Is the document placed on the platen glass correctly?
A Place the document approximately 1 / 8 " (3 mm) from the edge of the platen
glass.
