2) Turn the worm gear until the mark "      " on the top of

the lift cam of the rear bracket ass'y comes to the
center of the z-slot in the rear plate ass'y as shown in
the figure. (Z-slot is the slot in which bin pins are
inserted.)

(2) Turn the lift cam of the front bracket ass'y so that its

mark "     " faces with the mark "      " of the lift cam of the
rear bracket ass'y.

(3) With this condition, assemble the front bracket ass'y on

the front plate ass'y 2.

(4) After assembling the front bracket ass'y, be sure that both marks ("     ") on

both lift cams are facing each other as shown in the figure.

Detection of Paper Jam

• FA-S280 copy paper transport condition is monitored by the sensors shown

below. When paper is jammed, the jam position indicator (     ) blinks. at the

same time, "paper jam" is memorized by code number (J60). (Maximum 10

occurrences including options.)

• To recall paper jam codes, refer to the copier service manual "F8-06", page 4-

1(7).

(a) Jam conditions

• When the sorter paper feed sensor does not detect paper within a predetermined

time after the paper exit sensor in the copier detects paper.

• When the sorter paper exit sensor does not detect paper within a predetermined

time after the paper feed sensor in the sorter detects paper.

• When the sorter paper feed sensor and the sorter paper exit sensor detect

paper when the power switch is turned on.

To clear "paper jam" indication, remove the paper, reset the sorter mode and

select the sorter mode again.

• When the CPU P.C.B. can not control the machine or any trouble occurs, the

error code(Exx) appears in the message display of the copier and the machine

will stop.

• To clear Exx, release the sort mode and select the sort mode again.
