CHAPTER 2 BASIC OPERATION
· Slide Guide Lock
The ADF is equipped with a slide guide
lock so that the slide guides will not move any
farther than 297 mm (A4 length or A3 width).
If an original larger than 297 mm is used,
the slide guide lock may be released (to
accommodate up to 305 mm). The length of the
original, nevertheless, must be 32 mm or less.
