Reading of the document
To avoid skew feeding, documents loaded on the document tray are retained in the horizontal direction by the slide guide. Then, the documents are fed to the sep-
aration roller by the pickup roller, and separated one sheet each using differences in the coefficient of friction among the separation roller, documents, and separation
guide.
After that, the feed roller feeds the document onto the reading area, and the contact sensor reads out image data of the document; then, the delivery roller delivers
it to the output tray.
The document feed motor drives the various rollers of the ADF.
