[4] UNP ACKING AND INSTALLATION

14. Optional multi paper feed unit (SF-MF15) installation

Disconnect the power plug of the copier and perform the following procedures.

1 Open the front cabinet of the copier and lift the upper unit slowly

with the open/close lever.

Body open/close lever

Upper unit

3 Insert the positioning pins of the multi paper feed unit into the

installation holes of the copier. At that time, first insert the rear pins, then insert the front pins. (Check that the multi paper feed unit connecting pins are properly connected.) Then fix the multi paper feed unit with the two screws which were removed in procedure (2).

* Keep the right cabinet, which is required when the multi paper feed

unit is removed.

2 Attach the mechanical counter attachment plate

(LPLTM4963FCZZ) to the optical system base plate. At that time, be careful to avoid contact between the mechanicalcounter attachment plate and the main harness.

3 Attach the counter socket (SF71B) to the mechanical counterat-

tachment plate.

5 Cut off the notch section of the left cabinet, and attach theupper

cabinet left and the left cabinet to the copier.

4 Fix the counter socket with a screw and connect the countersock-

et harness and he copier harness. (Disconnect the 1P harness connector of the copier, and connectwith the counter socket harness.)

[5] DESCRIPTIONS OF EACH SECTION

Descri ptions are made on the follow ing sections:

1 Paper feed section 2 Developing section 3 Optical section 4 Process section 5 Separation/transport section 6 Fusing/paper exit section 7 High voltage section 8 ADU section (SF-2120 only)

In the c ase of SF- 2220:

The SF- 2220 is p rovided with th e three -way pa per fee d system . The tray is of the u niv er s al type and has capacity of 2 50 sh eets. Th e fr on t loading system allows the tray to be loaded from the lower side of the front cabinet. (The SF-2320 has the two-way paper feed system with one 250sheet tr ay and manual feed.) The tray has the capacity of 500 sheets (250 sheets for the SF-2 320). In addi tion to that, th e option al paper feed uni t allows loading o f 500 sheets more for the SF-CM15 (250 sheets for the SF-CM16).

2) Basic operati ons

(Tray paper feed operat ion)

When the CPFC (Cassette paper feed clutch) turn on, the paper feed roller shaft, t he paper fe ed roller, and the ta ke-up roller rotat e in the direction of A. At the same time, the limiter spring moves down the roller release arm. As a result, the take-up roller falls by its own weight onto the paper surf ace, start ing paper feed.

1 Open the front cover and lift up the upper clamshell. Remove two

fixing screws of the manual paper feed section, and remove the manual paper feed section.

(Note for assem bly)

1) There is the 8-pin connector on the back of the rear frame side. When assembling it, carefully insert.

2) The belt must be on the paper feed unit gear and the resist roller gear.

1-2. Paper feed roller ass’y removal

1) Remove the rear frame side electromagnetic clutch connector.

2) Remove the front frame side stopper and the bearing.

3) Remove the roller release arm spring from the paper feed frame.

2 Remove the four fixing screws (M4 x 10 x 1pcs, step screw x 1 pc)

of the paper feed unit, and lift the rear frame side of the paper feed unit and remove it. (Since there is the 8-pin connector on the back of the rear frame side, it requires some force to remove. Carefully pull it out straight.)

4) Remove the rear frame bearing, and one side of the paper feed roller ass’y will be disengaged. To remove the ass’y completely, remove the E-ring.

state automatically. The time to return to the initial state is set in the range of 30 - 120 sec in increment of 30 sec. This function can be cleared.

• When the copier is left without copying with the power ON, the power consumption is

automatically lowered to 60Wh. The time to start this function is set in the range of 1 min - 120 min.

• When this function operates, the pre-heat lamp on the operation panel is lighted.

To return to the initial state: Press any key on the operation panel. (If the COPY button is pressed, the machine returns to the initial state and performs copying.) If also the original is set or the tray is pulled out, the machine returns to the initial state.

• When the copier is left without copying with the power ON, the power consumption is

automatically lowered to 10Wh. The time to start this function is set in the range of 5 min - 120 min.

• When this function operates, al the lamps on the operation panel except for the pre-heat lamp

are turned off. To return to the initial state: Press the COPY button. The machine returns to the initial state.

• This function learns the use conditions of the copier to automatically control the time to start the

pre-heat function and the auto power shut off function to the optimum level. This function can be activated or inactivated. Cancel

• When this function is activated, the time settings in the pre-heat function and the auto power

shut off function are ignored.

• When the copier is left without copying for a certain period, this function is used to enable or

disable the function of lowering the power consumption.

• By use of the auto document feeder (option), originals of different sizes are fed manually.

• When this function is activated, set an original during the original feed lamp blinks after

completion of copying of the previous original, and the original is fed automatically.

• When the sorter (option) is installed, the interval between bins can be extended to facilitate to

take out the copy by pressing the copy take-out key.
