2. Features
(1) High productivity
1 Large capacity tray, cassette
Air paper feed tray (3,300 sheets) × 1
Air paper feed tray (1,000 sheets) × 1
Paper cassette (250 sheets) × 1
Manual paper feed tray (100 sheets) × 1
2 RADF is equipped with the large capacity tray (100 sheets,
80g/m2).
3 Duplex copying of max. 100 sheets is possible. (The duplex tray
capacity: 100 sheets, 80g/m2) 50 sheets for A3 (11″× 17″).
4 Large capacity toner hopper (Equivalent to 56K)
5 RADF realizes 100% efficiency of single copy from single docu-
ments.
6 The staple sorter of 50-sheets allows automatic after-process
(with the option sorter installed).
7 Unit structure
The employment of the unit structure allows quick recovery by
replacement of the unit in case of a trouble, shortening the recovery time.
8 Automatic copy density adjustment
This feature automatically adjusts the copy lamp voltage in each
copy mode depending on the copier conditions, eliminating the
need for copy density adjustment by the simulation.
(4) High picture quality
1 AICS (Active Image Control System)
The Sharp’s unique AICS (Active Image Control System) allows to
check toner concentration on the photoconductor drum by the
copier itself, correcting a change in density due to deterioration
automatically. This maintains high quality copies for a long period.
(2) High reliability
1 Air feed system
The air feed system allows smooth paper feed. It utilizes air pressure to separate paper without contact, stabilizing the paper transport force, reducing double feed and paper jam.
2 Auto recovery
In case of a paper jam, the trouble may be canceled by removing
the minimum number of paper. (The drive section of the copier is
divided into several sections, which are driven separately. In case
of a paper jam, transport is continued or stopped depending on
the jam position. By removing paper from the sections which are
not related to the paper jam, the trouble is canceled, reducing
paper jam treatment.)
3 Communication feature
Communication between the copier and the service center is possible through the telephone line. The serviceman can identify the
trouble position in advance to servicing, shortening the recovery
time. (Option)
4 Full frame structure
The frame of the machine is made of a strong structure, enabling
long-period use that is highly durable.
(3) The LCD screen with the backlight allows each
operations.
1 Key operator program
Use of the key operator program allows setting and adjustment of
the operation mode according to the office needs. The department
control counter is a standard provision.

Though the shapes of the photoconductor drum, developer, toner,
and the fusing section cleaning roller are similar to those of the SD2060, they are not compatible with each other.
The differences are as follows:
1) Photoconductor drum
If installed erroneously, the error code F2 is displayed.
2) Toner
The port shape of the toner bottle differs to prevent against erro-
neous installation.
The characteristics of toner differ from each other. The proper
toner must be used to obtain stable picture quality at proper density.
3) Developer
Proper developer must be used to obtain stable picture quality at

2) Power voltage
Measure the power voltage during copying to check that it is
within the range of the rated voltage ±10%.
If the voltage is not within the above range, use wider wires to
reduce impedance. (An electrical work is required.)
There is a method to use a step-up transformer. In this case, use
the transformer of greater capacity than the machine’s max.
power consumption.
3) Power frequency, waveform
The frequency must be the specified level ±2%. If the frequency is
distorted, a trouble may be caused.
4) Safety
Be sure to ground the machine.
5) Power plug
Check the shape of the power plug, Do not use a plug of different
shape.
(1) Delivery space
Check the door sizes to allow delivery of the machine in advance.
(2) Installation space
Allow the following installation space around the machine for proper
operations and performances.
The space for options must be also considered.
Especially allow enough space at the back of the machine. If the back
space is insufficient, heat radiation and the dust proof function are
prevented, suppressing the machine performances and causing troubles.

60cm
80cm
120cm
(3) Power source (capacity, voltage, frequency,
safety, plug)
If the power source requirements are not satisfied, the machine cannot display full performances, and may cause dangerous troubles.
BE sure to follow the following instructions:
1) Power source capacity
Check that the power capacity is enough as specified below. If it is
insufficient, it must be corrected.
Current capacity (Japan 15A specification)15 A or above
Japan 20A specification machine:20 A or above
EX 100V series:16 A or above
EX 200V series: 9 A or above
(4) Floor strength and level
The machine is heavy, and options add further weight. Be sure to
check the floor strength for safety.
If the machine is not leveled properly, the toner concentration control
is not performed properly, affecting copy quality adversely.
(5) Direct sunlight, dust, temperature, humidity,
gases, chemicals, vibrations
1) Temperature, humidity
The storage and operation of this copier is assured under the
following conditions. If the following conditions are exceeded, the
copier may not display full performances, causing troubles.
Especially when the humidity is too high, paper absorbs moisture
to cause paper jams and dirty copy.

Humidity (RH)
85%
60%
20%
5) Vibrations
Do not install machines which produce vibrations around the cop-
ier. If vibrations are applied to the copier, copies may be blurred
and troubles may be caused.
15°C
Temperature (°C)
Do not install t he copie r near a he ater, a cooler, or a hum idifier. If
installed, the copier may form dew and cause troubles. Be careful
of ventilation, too.
2) Dust
If dust enters the copier, it may cause dirty copy, paper jams, and
short lifetime.
3) Direct sunlight
If the copier is exposed to direct sunlight, the external section may
be discolored, causing poor copy quality.

2Delivery formTransported in packed conditions.
(1) Equipment, facility, man power
It is advisable to use a fork lift for efficiency and safety. If a fork lift is
not available, six men are required to move the machine. The copier
is very heavy. Consider for safety in delivery and installation work.
Transport of the copier must be made in the packed conditions to the
installing place (building).
(2) Delivery form
Remove the copier from the packing case outside the installing building, then carry it inside the building.
Use a fork lift.
(If a fork lift is not used, 6 men power
is required.)
4) Gases and chemicals
Do not install the copier near gases and chemicals. Especially be
careful of a diazo-type copier, which may produce ammonium
gas. The copy quality may be adversely affected, causing troubles.

(Note) When the copier is not used for a long time, release the
cleaning blade pressure.
(Note) Developer for the SD-2060 cannot be used for the SD-2260.
(3) Toner concentration control level setting
Virgin developer has been adjusted to the specified toner concentration. This density is detected by the sensor and stored. After that, the
toner concentration level is used as the reference level, and developer is controlled to provide the level same as the virgin developer.
The above operation is performed with SIM 25-2.
When developer is replaced, this procedure must be performed.
1) With the front cabinet open (with the front cabinet open/close
detection switch OFF), turn on the power to enter the SIM 25-2
mode.
SIMULATION NO. 25
INPUT 1 ∼ 2
1. Toner concentration SENSOR MONITOR
2. AUTO DV DENSITY
(Note) Do not turn on the power with the front cabinet closed (with
the front cabinet open/close detection switch ON). Toner
would be supplied to the developing unit and the toner concentration of the virgin developer may not be the reference
level.
2) Close the front cabinet. (The front cabinet open/close detection
switch is turned ON.)
3) Press the START button.
Developer is stirred for 3 minutes, and the reference toner con-
centration level is memorized.
Be sure not to cancel SIM 25-2 until stirring of developer is com-
pleted in 3 minutes.
If EU trouble or EL trouble occurs midway, check for abnormality
in the developing unit.
