- Staple Finisher-B1: FKU18827
- Booklet Finisher-E1: FYJ14501

Cause
When the swing guide assembly is opened during printing, the upper portion of the swing guide assembly
[1] rarely but may come in contact with the switch lever (F)/(R) [2], so that the switch lever may be
moved upward.
At this time, if the force of the tension spring [3] pulling the switch lever is too strong, the switch lever will
be pulled back downward by the tension spring, this will make the swing guide assembly closed and
generate the above mentioned issue.
[Reference] With a normally working Finisher, the swing guide assembly will not come in contact with the
switch lever even if the swing guide assembly is opened during printing.
