[1] PRODUCT OUTLINE

1. Product features

(1) Compact body

• Compact body size

The body width of 600mm is the smallest in the class.

• The employment of the front loading tray and the folding-type multi

manual paper feed cassette realizes the small occupying area. (Option)

2. System configuration (options)

10-bin sorter SF-S 17

10-bin staple sorter SF-S54

(2) Clean copy gentle to the environment

• Silent design,

• Low level of ozone, use of recyclable materials

• The energy-saving mode reduces the power consumption.

(3) High capacity of copying

• Warm-up time is less than 35 sec. The first copy of 5.3 sec (SF-

2020) or 5.8 sec (SF-2120).

(4) Fully expandable system. (Refer to "2. System configuration.")

[4] UNP ACKING AND INSTALLATION

1. Unpacking

2 Avoid high temperature and high humidity, and avoid sudden

temperature change. (Avoid installation near a cooler or a heater.) If not, paper absorbs moisture and dew forms in the machine, causing paper jam or degraded image quality.

(Standard condition): The best condition to use the machine. 20 ∼ 25°C: 65±5%RH (Temperature and humidity): 15 ∼ 30°C

2. Installat ion

Installing conditions

The surrounding conditions of the machine affect the machine performance gr eatly. Use great car e for the fo llowing items.

(1) Enviro nm ent

1 Avoid direct sunlight, and avoid installation near the window. (Cur-

tains or blinds must be shut completely.) If not, the plastic parts and the original cover may be deformed. Even if the window is of frosted glass, there is no difference.

15 30 35

3 Avoid dust and vibrations.

If dust enters the machine, malfunctions may occur.

4 Avoid installation to an unstable place.

Keep the machine in horizontal state to maintain the performances.

˚C

4 – 1

5 Avoid installation to a poorly ventilated place.

6 Avoid installation to a place where there are flammable materials

or ammonia gas, etc. If the machine is installed near a diazo copier, the picture quality may be degraded and malfunctions may occur.

(5) Grounding wire connection

1 Connect the grounding wire to prevent against a danger. 2 When connecting the grounding wire, connect only to the ground-

ing object (the grounding terminal of the power outlet, etc.) and never connect to a gas pipe.

Grounding termin al

7 Install near a power outlet.

(2) Space aroun d th e ma chine

Install the machine with its rear side about 10cm apart from the wall in order to allow space to ventilation by the cooling fan. Also allow eno ug h space around the ma chine for prop er op eration.

(3) Installation base

Set the machine in horizontal position in the following procedure. Be sure to use a leve ling instrumen t (UKOGM0054CSZZ) to install the machine on a flat, horizontal place.

(Note) If the machine is not in horizontal position, the toner density

control function may not work normally, resulting in degraded picture quality.

(4) Power sour ce

1 Use the power source of the rated capacity. 2 Avoid complicated wiring. If not, the breaker or the fuse may be

overloaded.

Move the front part of the tray in direction B, tighten first the two "a" securing screws then the two "b" securing screws, then make another copy to check whether the copies come out properly centered.

13. Tray paper size selection (Described with the SF-2020)

Select the necessary size accor ding to the follow ing proc edures. (A5 size paper is treated as a special size. When shipping, the size is set to A3.)

1. Fit the parti t i on plates in the tray according to the

paper size (hori zontal and vertic al ).

Be sure to fit with the paper scale position. Partition plate A can be slid. Hold the fixing grip and slide it to the proper pap er siz e po sition. Parti tion plat e B is of insert-type . R em o ve it and inse r t to t h e su it a ble paper size position.
