HINT
• When scanning semi-transparent documents, set the density to light to
avoid a bleed through.
• To prevent the rollers from becoming dirty, avoid scanning documents con-
taining large areas written or filled with pencil. If scanning of such docu-
ments is inevitable, clean the rollers more frequently.
• When feeding errors, paper jams and multifeeds occur frequently, refer to
“2.9 Setting the Paper Thickness” on page 29.
