CHAPTER 5 PICK-UP/FEEDING SYSTEM
The copier's cassette is designed to apply auxiliary pressure on paper of B4 or wider. The
auxiliary tension spring acts on the lifter through the cut-off in the bottom of the cassette when
the side guide plate is slid to the outside. In the case of paper narrower than B4, the spring
remains slack and therefore does not act on the lifter.
