A612V501-2.img

The finisher recognizes the base copier type by receivin g the copier’s paper exit speed data when the main switch is turn ed on. The pa per transport speed depends on the base copier.

After the copy is completed, the paper is directed to the finisher. If the sort/stack mode is selecte d, the junction gate [A] dire cts the paper upwards to send it to the shift tray [B]. In these modes, th e shif t tra y is shifte d fro m side to side to stagge r and sepa rat e set s of cop ies. The amount of shift is approximately 30 mm.

When the staple mode is selected, th e jun ctio n gate direct s the paper downwards to send it to the jogger un it [C] . Ea ch time a copy is delive red to the jogger unit, the position ing roller [D], the alignment brush ro ller [E ], and the jogger fences [F ] squ are the stack of copies. After the final copy of the set is squared, the set is stap led , an d th en delive red to th e shif t tray.

Depending on the sele cte d finishing mode, the copie s are directed up or down by the junction gate [A ], which is controlled by a solenoid. This happens after the ent ran ce sen sor [C] has been activated.

solenoid [B] is energ ized . The n, the junction gate directs the copies down to send them to the jogger unit.

(2) When the exit sensor of the copie r is activat ed while in th e sort /st ack

mode, the solenoid stays off. The junction gat e dire cts th e copies up to send them to the shif t tra y.

The shift tray lift motor (a dc mot or) [B ] con tro ls the vertica l posit ion of the shift tray [A] through gears and timing belts [C]. When the main switch is turned on, the tray is initialized at the upper position. The tray’s upper position is detecte d whe n th e shift tray pushes up actuat or [D] unt il the actuator has just left the stack height sensor 1 [E], and is now between the two sensors [E] and [F] .

During copying, the actuator feeler gradually rises as the copy stack grows, and the actuator gradu ally move s towa rds sta ck heig ht sensor 2. In sort/stack mode, if the actuator remains inside stack height sensor 2 [F] for 4 s, the shift tray lift motor lowers the tray unit for 50 ms. In staple mode, if th e act uato r leaves stack height sen sor 1 fo r 4 s during a copy run , th e mot or lowe rs t he tray until stack height senso r 1 is actua ted. This mean s the tray lowe rs earlie r in staple mode, to preven t pro ble ms cause d by sud de n arrivals o f sta ple d stacks of paper on the tray (sta plin g is don e insid e the machine, and the stapled copy is fed out to th e tra y; the second copy may suddenly exceed the space currently availab le on the tray).

For both modes, the shift tray will rise when the user takes th e sta ck of pape r from the tray during cop ying.

When the tray reaches its lower limit, actuat or [H] enters th e lower limit sensor [G], and cop ying stop s. After copying ends and th e mach ine stop s, the tray is raised to its uppermost position 4 s after the copies are removed.

The shift tray upper limit switch [I] prevent s the drive gears fro m bein g damaged if stack heig ht senso r 1 fa ils. When the shift tray pu she s up th e shif t tray positioning roller [J], the switch cuts the power to the shift tray lift motor.

In the sort/stack mode, the shift tray [A ] move s from side to side to stagg er and separate the set s of cop ies.

The horizontal position of the shift tray is controlled by the shift moto r (dc motor) [B] and the shift cam (helical cam) [C]. After one set of origina ls is copied and delivered to the shift tray, the shift motor [ B] start s rota tin g, driving the shift cam through the timin g belt. The pin [D] fixe d to the shift tray base plate [E] is position ed in the groo ve on the shift cam, creating the side-to-side movement required to sta gg er th e cop ies.

When the shift cam has rotated 180 degrees (when the tray is fully shifted across), the plate [F] on the shift cam pushes the actuator [G] of the shift tray half-turn sensor [H] and the shift motor stops. The next set of copies is then delivered. The moto r ro ta te s, rep ea ting the same process and moving the tray back to the previous posit ion .

In staple mode, each sheet of cop y paper is vertically and horizontally aligned when it arrives in the jogger unit.

For horizontal pape r align men t, the jogger motor [A] moves bot h th e front and the rear jogger fences [B ] to align the copies.

For vertical paper alignment, th e positio nin g roller [C] an d the alignment brush roller [D] push the copy again st th e stack stopper [E].

After the trailing edge of the copy passes th e jog ger unit entrance sensor [F], the positioning roller sole no id [G ] is energized for 280 ms to push the positioning roller int o conta ct with the paper. The positioning roller rotates to push the paper back and align the trailin g edge of the pape r aga inst the stack stopper. Both the positioning roller and the alignme nt brush roller are driven by the lower transport drive motor throu gh the timing belt [H].

After the trailing edge of the copy passes th e jog ger unit entrance sensor, each jogger fence moves inward 5 mm. They stop 2 mm away from the paper edges. (2)

Just after the position ing roller pushes the copy back, each jogger fence moves inward 2 mm more so that the leaf spring [B] on the rear jogg er fe nce pushes the copy side ed ge slight ly. (3)

After a copy is stacked in the jogg er tra y, the jogger fences move back 7 mm from the copy edge for the next copy.

The staple hammer [A] is drive n by th e sta ple r motor [B] via gears [C], two eccentric cams [D], and two links [E] .

When the aligned copie s are bro ug ht to th e sta pling position by the positioning roller, alignment brush roller and jogger fences, th e sta ple r moto r starts. When the cams comp lete one rotation, th e sta ple hamme r h ome position sensor [F] tu rns on , de te cting the end of the stapling ope rat ion. The stapler motor then stops.

There are two sensors in the stapler un it. One is the staple end switch [G ] fo r detecting staple en d con ditions (it detects when there is o nly one sheet of staples left in the cartridg e). The othe r is the cartridge set switch [H] for detecting whether a staple cartridge is installed.

When a staple end or no staple cart ridge condition is detecte d, a message is displayed advising the opera to r to inst all a staple cartridge. If this condition is detected during a copy job, the indication will appear, but will not stop the copy job in any way.
