			DATE:	10.08.99
Location	:	ADF PICKUP ASSEMBLY
Subject	: ADF PICK-UP JAM THAT OCCURS WITH 200G/M2 PAPER
Reason	: When an original using a thick and stiff paper is fed from the ADF, the original may strike the edge of
		the copyboard glass with the consequence of folding at the leading edge of the original or an
		occurrence of a pick-up jam. To overcome this problem, a spring with higher tension has been made
		available to the field. And in this connection, a formal engineering drawing change has been made.
Details	:	<Symptom>
		When an original using a thick paper is fed from the ADF, the original may strike the edge of the

copyboard glass with the consequence of folding at the leading edge of the original or an occurrence of a pick-up jam for the original.

<Cause>

When a thick and stiff original is fed, it can push down the lower guide (for guiding the paper to the path the paper is to follow) to a position below the edge of the copyboard glass. When that occurs the original may strike the glass with the consequence of folding at the leading edge of the original or an occurrence of a pick-up jam for the original. (See Figure 1.)
