[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.
2. System configuration (options)
(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 45 sec. The first copy of 5.3 sec (SF-
1020) or 5.8 sec (SF-1120).
(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.

2. Installat ion
Installing conditions
The surrounding conditions of the machine affect the machine perfor­mance gr eatly. Use great car e for the following 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.
20
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-1020)
Select the necessary size accor ding to the following 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 t o th e suitable paper size position.

Descri ptions are made on the following 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-1120 only)
In the c ase of SF- 1020:
The SF- 2020 is p rovided with th e three -way pa per fee d system . The tray is of the u niv er s al type an d has capacit y o f 2 50 sheets. Th e f ront loading system allows the tray to be loaded from the lower side of the front cabinet. (The SF-1 120 has the tw o-way paper feed syst em with one 250-sheet tray and ma nual feed.) The tray has the capacity of 500 sheets (250 sheets for the SF-1120). 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 pape r feed.

Use of th e op tio nal t wo- stag e pa pe r fe ed u nit f or t he SF -CM1 5 ( one­stage p aper feed unit for the S F-CM16) an d the spa re tray allow s a variety of system configurations.

When the CPFC turns off, rotation stops and the take-up roller is pushed up to the original position by the r oller rel ease arm spring.
(Multi manual paper feed operation)
When the MPFS (multi paper feed solenoid) turns on, the spring clutch rotates to pr ess the take- up roller on t he paper, feeding the paper.
