C560V505.wmf
[D]
C560V507.wmf
Copies exiting the printer enter the sorter. The paper delivery table has been
raised to the sort mode position when this mode has been selected. Copies
are delivered to the bins [A] throu gh the 1st tra nsp ort belt [B] in the correct
order. The copies in the bins are arranged by the jogger bar.
The 1st sorter can hold 20 sorted copies. If the 2nd sorter is in sta lled next to
the 1st sorter, an additional 20 copie s can be sorte d.
When the 20th copy has been fed to th e 1st sorter, the bin unit [C] is at its top
position and the bin unit has raised the 2nd tran sport unit [D] to its ready
position. The 21st to 40 th copies are transported to th e 2nd sorter. After the
final copy of an origina l pag e has passed the 2nd transport unit , th e 2n d
transport unit and 1st sorter bin unit and 2nd sorter bin unit are lowe red to the
initial position, an d th e machine will transport copies t o th e bin s of the 1st
sorter again.
When the final set of copies has been jogged, the bins all go to home
position, then the stap le un it sta ples the copies stacked in the 1st bin. Then,
the bin unit is moved up so that the next bin is at th e stapling position. When
the final set of copie s has be en stap led , the bin unit is lowered to the home
position.

The 1st transport unit consists of the paper de livery ta ble [A] and paper
transport belt unit [B]. These two units shift to either the uppe r or lower
position together. The upper position is used for th e sort mode ; the paper [C]
passes through the paper transpo rt belt unit to the bin unit [D] . The lower
position is used for the non-sort mode; the paper [E] is delivered to the paper
delivery table.

When the paper delivery table motor [A] rotates coun terclockwise, the 1st
transport unit is raised thro ug h the gears [B] and drive chains [C]. The motor
stops when the actuator [D] on the chain enters the 1st transport sort mode
position sensor [E]. The paper de livery ta ble moto r st op solenoid [F] turns
on/off at the same time as the pape r delivery table motor. When the solenoid
turns off, the sole no id leve r [ G] eng ages the motor gear [H]. This locks the
1st transport unit at eithe r the upper or the lower position. If the paper
delivery table motor does not sto p its cou nt erclo ckwise rot at ion, the 1st
transport upper limit switch [J] turn s off the 24 V line to the mot or.
When the paper delivery table motor rotates clockwise, the 1st tra nsp ort unit
is lowered. The motor stops when the actu ator actuates the 1st transport
non-sort mode position sensor [I].

The 1st transport motor [A ] drives the transport belts [B] throu gh the timing
belt [C] and transport rollers [D] . The motor has a timing disk [E], and the 1st
transport motor rotat ion sensor [F] uses this for monitoring and con tro lling the
1st transport moto r rotation speed. The 1st transport fan motor [G] is installed
below this unit. This fan moto r sucks air through the holes in the transp ort
belt to hold the paper on the transport belts.

Each bin has a small roller [A] at each end. The bin un it is supp ort ed by
springs [B] which are attach ed to the sort er main body. There are two helical
wheels [C] on each side. The slit in the helical wheel engages the small
rollers [A] at both ends of each bin. The bin s are atta ched to the sorter main
body at the cutou ts in th e main body side plates [D] and by engaging the
small rollers to the helical wheels. The load on the helical wheels during liftin g
is decreased by the two springs.
The bin shift motor [E] rota te s t he helica l whee ls forward and in reverse
through the timing belt [F]. When the helical wheels rot ate, the small rollers
move up and down along th e gro oves [G] in the helical wheels. This enab les
the bin unit to move up and down.

There is a flat portion [A] in the cen te r of the gro ove in each helical wheel.
Without this, the helical wheels would rotate in reverse at the bin stop

sensor [B] is actuated while the small rollers [C] are on the flat portion of the
helical wheel. The bin shift motor stops, and the bins do not move so that
paper can exit to the bin at this moment.

whenever paper is fed out to th e bin. Also the jogger bar moves and holds
the paper stack for stapling. Ordin arily, the jogger bar is at the home position.
It moves to the rear of th e sta ck (t he dista nce mo ved by the jogg er ba r
depends on the selected paper size [B]). Then, after jogg ing , the motor
moves the jogger bar back to its ho me po sitio n. The motor stops when the

If there is an obstacle [A] und er the bin unit [B] and the bin unit can no t be
