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.

(1) When the exit sensor of the copie r is activat ed while in sta ple mode , th e

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.
