ADF PICK-UP ASSE MBLY

FOL DING OF DOCUMENT’S LEADING EDGE IN ADF

To communicate countermeasures for the possibility of the document’s leading edge becoming folded
when the accuracy as to the position the ADF reversing flapper stops is deficient or when the reversing
guide is not completely pushed in and properly seated after attending to the problem of this flapper
remaining folded up through mishandling.

<Symptom>

When using the ADF to copy, there are cases where the document’s leading edge becomes folded.

<Cause>



In case the accumulated tolerances of the parts get too close to the limits, the document may strik e
the copyboard glass and the document’s leading edge may become folded.



The reversing flapper is replaced as the measure to deal with the situation of breakage consequent
to the user getting his fingers caught to the reversing flapper in clearing a jam. But failing to
notice during the replacement that the reversing guide has not been completely pushed in and
properly seated could result in the document’s leading edge to become folded.

<Factory measure>
By eliminating the rib of link B (Parts Catalog TY8-31DV-000 page 30-97) and changing to the type
with a different angle, the folding up of the reversing flapper was restrained, and the striking of the
document against the copyboard glass prevented.
