• If paper jams or double feed errors occur, set [Document type]
to [Extra-thin paper] in the Detailed Settings screen. In
addition, limit the number of documents placed on the scanner
to about 10 sheets.
• A dirty or worn feed roller, or documents stuck together as a
result of static electricity are common causes of paper jams or
double feed errors.
If the feed roller is dirty, clean it. If paper jams or double feed
errors continue to occur even after cleaning, purchase an
Exchange Roller Kit and replace the rollers (feed roller and
retard roller). (See p. 181.)
