1. Model Name:
ARFN2
2. Description:
Intermittent paper jamming in the AR-FN2 finisher.
A sheet of copy paper is sent to the top tray when the bottom tray has been selected, a
jam error is then displayed on the copier display. This is caused by the Solenoid PRSL
(P/G 7-2) being unable to move the Flapper (P/G 7-1). This jam will give an indication in
the jam map of FJTES_N.

4. Action:
The flapper arms (P/G 7-12) on the K-Frame F (P/G 2-25) and K-Frame R (P/G 2-26) is
sticking on some adhesive. Therefore, the Solenoid PRSL is unable to move the Flapper
to divert the copy paper.
This adhesive has been caused by the small felt pads, on the lower Flapper arm
stoppers on the K-Frames F & R, moving out of position over a period of time. These
pads were introduced to reduce noise. Please see photographs below:-

The Lower Flapper Stopper Arm Pad is not flush with the end of the stopper. Over a
period of time it moves into the finisher therefore, leaving a small amount of adhesive
exposed. Due to the amount of play in the back-to-front movement of the Flapper, the
Flapper Arm may come into contact with this adhesive. The timing of the Flapper
movement is then delayed and the above symptoms are caused.

To prevent this problem in the short term, please remove the Lower Stopper Pads on the
K-Frames F&R and remove all signs of adhesive.

A long-term fix will be the addition of a new Lower Stopper Pad. Details regarding Part
Numbers for these items will be issued by Fast Facts in the near future. These new pads
will be available free of charge.
