2.3 ELECTRICAL COMPONENT DESCRIPTION
Refer to the electrical component layout on the reverse side of the Point to Point
diagram (on waterproof paper).
Symbol Name Function Index No.
Motors
M1 Bin Lift
Lifts and lowers the bins via a belt, gears, and
wires.
23
M2 Jogger
Drives the jogger bar to jog the copies against
the front side plate.
20
M3 Grip
Drives the grip assembly into the bin to grip the
copies and bring them to the stapling position.
13
M4 Stapler Feeds the staples and drives the stapler hammer. 12
M5 Roller Drive
Drives the proof tray exit, vertical transport
rollers, and bin transport belts.
1
Circuit Board
PCB1 Main Control Controls all sorter stapler functions. 18
Solenoid
SOL 1 Turn Gate
Opens and closes the turn gate to direct the
copies into either the proof tray or the bins.
6
Sensors
S1 Bin Lift Timing -1
Monitors the rotation of the bin lift motor by
detecting the timing disk.
24
S2 Bin Lift Timing -2
Controls the stop timing of the bin lift motor so
that the bin lift timing sensor no. 1 can detect the
timing disk properly.
25
S3 Jogger H.P.
Detects whether the jogger bar is at the home
position.
19
S4 Paper
Detects whether there are any copies under the
hammer.
8
S5 Bin (LED)
Detects whether there is any paper in the bins
(light emitting element).
3
S6 Bin (Photo transistor)
Detects whether there is any paper in the bins
(light receiving element).
17
S7 Grip H.P.
Detects whether the grip assembly is at the
home position.
16
S8 Bin H.P.
Detects whether all the bins are in the down
(home) position.
15
S9 Bin Exit Detects paper jams at the bin exit area. 5
S10 Proof Tray Exit Detects paper jams at the proof tray exit area. 4
S11 Roller Drive Timing
Monitors the roller drive motor speed by
detecting the timing disk.
