MODEL: F40 RDH
(Phenomenon)
The original misfeed indicator lights because the stack of originals cannot be fed into the
RDH feed-in position, even after the start key is pressed.
As reported from the field (the occurrence ratio is low), it happens about 100
∼
200 k
copies after the machine installation. And, the earliest one appeared after about 50 k
copies.
(Cause)
The original stopper solenoid lever which does not have sufficient durability breaks due to
material fatigue. Then, the original stopper gate cannot open.
(Action required)
Replace the stopper solenoid lever with a new one.
To increase durability, the material and shape of the solenoid lever was modified as
follows:
(P/N A4991332)
(P/N A4991332A)
(old type)
(new type)
NOTE:
- This modification has been implemented from ’91 November production onward.
- The new part is now available at our parts center.
