[E]

[J]

A591V501.img

Copies exiting the copie r ent er the sorter or the by-pass tra y [A] dep en din g on the by-pass tray gate [B] posit ion . In normal operation, copies are sent to the sorter, if paper jams occur in the sorter, the remaining papers in the copier are fed to the by-pass tray.

If sort/stack mode is not selecte d, copies are delivered to the proof tra y [C] through the diagonal transport unit [D], the horizontal transport unit [E], and the distribution unit [F].

When sort/stack mode is select ed, copies are delivered to the bins [ G] in order.

The copies in the bins are arranged by th e jog ge r arm [ H]. If staple mode is selected, when th e last pag e of the origin al is delive red to

the 1st bin, the staple unit [I] sta rts sta pling the copies in each bin. The 1st sorter has capacity to hold 20 sorted copies. If the 2nd sorter is installed next to the 1st sort er, an additional 20 sorted

copies can be sorted. After the 20th copy is fed to the distribut ion unit of the 1st sorter, the relay

gate [J] moves to the uppe r posit ion and the 21st copy is transpo rted to the 2nd sorter. After the final copy of the designated number has passed unde r the relay gate, the relay ga te mo ves do wn to transport copies to the bins of the 1st sorter again.

Depending on the by-pass t ray ga te [A] position, paper fed from th e cop ier enters either the sort er or th e by-pass tray [B].

The by-pass tray gate is driven by the by-p ass tray gate motor [C]. Under normal operating conditions, the by-pass tray gate is in the home posit ion (H.P. sensor [D] is actuated) to delive r co pie s to the sort er. If a sorter paper jam occurs, the gate rotate s on its sha ft [E] unt il the upper tray gate position sensor [F] is actuated and stops.

2.2 DIAGONAL TRANSPORT

[B]

[E]

[D]

A591D502.img

[C]

[E]

A591D503.img

Paper entering the dia go na l t ran sport unit is transported do wn to the horizontal transpo rt un it. The front side of the paper advances more than the back side due to the front transport roller [A ] be ing larger than the back rollers. This causes the paper to skew as it ente rs the diag onal transport unit. This skew prevents the diagona l t ran sport guide [B] from catchin g the edge of the copies.

The paper is then moved to the fron t by the diagonal transpo rt rollers [C]. Where it is aligned as it is guided by th e dia go na l t ran sport guide [B].

The brake roller [D] prevents the rear side of th e pa per f rom fa lling forward. If the paper is traveling lengthwise, the pressure release solenoid [E] turns on

to prevent over skewing.

[C][A]

A591D504.img

The distribution section has the distribution rollers [A], 20 bin gates, and 20 bin solenoids.

When a bin gate solenoid [B ] is off, the return spring [C] holds the bin gate [D] out of the paper path, allowing the copies to pass to th e up per b in.

The appropriate bin gat e sole no id turns on and opens the bin gat e. The ot he r solenoids are off. The copies go to the bin [E] throu gh the gate.

A591D506.img

Ordinarily, the side bar [A] is in the home posit ion . It moves to within 10 mm of the rear of the selected paper size. The side bar is driven by the side bar motor [B] through the gears and a timing belt.

The jogger arm [C] home position is 10 mm in front of the paper. After the paper passes the jam sen sor, the jogg er arm move s twice du e to

the forward and reverse rotation of the jogg er mot or [D]. Jogger arm movement is controlled through the link [E] and jogger bar [F].

The reverse rotation of the jogger motor preven ts motor lock caused by an overly stiff paper stack. Even if the ove rly stiff paper interferes with the jog ger arm movement, the arm returns to its home position via the reverse rotation of the jogger motor.

2.5.1 Gripper

A591D508.img

The grip unit [A] grips and moves the jogged paper to the staple position and returns the stapled paper to the bin. The grip solenoid [B] and grip moto r [ C] are built into the grip unit. The motor moves the grippers [D] back and fo rth, and the solenoid [B ] con trols paper clamping.

When the grippers reach the paper in the bin, the grip solen oid turns on and the grippers grasp the pap er. The lower gripper arm has a shorter stroke to pre ven t it from disturbing the jogged pape r in t he b in .

Paper gripped by the grippers is moved by the grip motor into stapling position. Resetting the main PCB DIP SW1 01 -1 to 101 -4 adjusts the stapling position (0.5 mm increments).

The stapled paper (held by the grip per arms t hro ug hout stap ling ) is ret urn ed to its original position. The grip solenoid turns off to release the stapled paper, and the gripper arms return to their original positio n.

The grip H.P. sensor [E] confirms th at the grip un it has retu rned to its home position.

2.5.2 Stapler

The paper sensor [A] preven ts sta pler operation when there is no paper in position. Also, it detects staple error if the paper sen sor remains actuated when the stapler finishes its operation.

The staple motor [B] drives the stapling mechanism and transporting of the staples from the cartridge [C].

The staple end sensor [F] checks if staples are present.
