Cannot Scan the Correct Area on the Scanner Glass

❏ Make sure the original is placed correctly against the alignment marks.
❏ If the edge of the scanned image is missing, move the original slightly away from the edge of the scanner glass.
❏ When scanning from the control panel and selecting auto scan area cropping function, remove any trash or dirt
from the scanner glass and document cover. If there is any trash or dirt around the original, the scanning range
expands to include it.
❏ Select the appropriate document size in the scan settings. If you have placed the printer in direct sunlight or
near a light source, the scanner glass may not detect the document size correctly.
