[1] PRODUCT OUTLINE
1. SD-2060
The SD-2060 has an original replacement speed of 60 sheets (A4 and 8.5"x11") per minute using the RADF as well as a copying speed of 60 sheets per minute. In addition, the air feed system reduces the possibility of paper misfeed and the AISC (Active Image Control System) corrects deterioration in copy quality, thereby providing higher reliability. The large liquid crystal display allows mproved maneuverability for the operator and service technician. Auto job recovery This new function allows a misfeed error to be cancelled automatically by removing the minimum number of misfed paper (s) in case of a misfeed error. The drive section of the main body is divided into several blocks which are independently driven, allowing paper feed in the blocks after the misfeed block, and minimizing the number of jammed pages to be removed after the misfeed error.
3 Communication error
The SD-2060 can communicate with a remote service center through the telephone line. This feature allows the service technician to identify the error position in advance to making a service visit, thereby reducing the servicing time.
2. Target usage
Copy volume range: 20,000-80,000 copies/month Average copy volume: 30,000 copies/month
(3) Ease of operation using the LCD message display
1 Key operator programs
By using the key operator programs, various mode settings and adjustments can be performed according to the user's requirements. Accurate account control and proper billing for copy usage can also be accomplished with certain key operator codes.
3. Product features
(1) High productivity
1 The newly developed RADF realizes 100% efficiency in switching
from single copy to duplex copy.
2 Automatic after-process functions when using the 50-sheet staple
sorter (SF-S53).
(4) High copy quality
1 AICS (Active Image Control System)
Equipped with SHARP's unique AICS (Active Image Control System), Toner density on the photoconductor drum is regularly monitored, and any variation in density due to deterioration is automatically corrected, maintaining high copy quality throughout the life of the photoconductor drum.
3 Full frame & unit construction
The frame of the SD-2060 is made of a high strength, rigid construction. Because of this, it can endure long period operations. In addition, the modular construction allows rapid replacement of the sub-assemblies in case of trouble, minimizing down time of the machine.
(2) High reliability
1 Air feed system
By utilizing air pressure without machanical contact, the paper transport capability is more stabilized than the conventional roller feed systems, reducing the possibility of double feed and misfeed.

[4] PROCESS (Photoconductor drum and cleaning unit)
1. Basic theory
With the indirect static copier, a plain paper is used for the copy paper. As a latent static image is formed on the surface of the photoconductor, the image is then developed into visible (toned) image using the toner. Then the toner is transferred onto the copy paper. The plain paper copier (PPC) has six basic processing steps of corona charge, exposure, development, transfer, cleaning, and discharge. The cleaning step prepares the photoconductor surface for repeated use.

(3) Types of photoconductors
The principal materials of a photoconductor are zinc oxide (ZnO), amorphous selenium (amorphous Se), selenium alloy, cadmium sulfide (CdS), amorphous silicon (amorphous Si), and organic photoconductor (OPC).

6 The charge remaining on the photoconductor surface (residual
charge) is removed.

(2) Photoconductor
While some materials conduct electricity, others do not. Materials, therefore, can be put into three categories of conductor, semiconductor, and insulator. For these categories are conceptual, distinct classification is difficult. Generally, the following is applied. Material whose specific resistance is over 103cm is called an insulator and under 103cm is called a conductor. Those which existing between the two is normally called semiconductor. A Conductor always has the electrical conductivity, while semiconductor does not. But, it may become conductor under certain conditions. The photoconductor used in copiers is an insulator when not exposed to light, but its electrical resistance abates when exposed to light. When exposed to light, the photoconductor surface becomes conductive. Material having the property to become conductive in light (photo conductive phenomenon) is a photoconductor or photosemiconductor.

Characteristics of organic photoconductors
[Acceptor potential]
The resistance in the dark area of the photoconductor decreased as the electric field increases among layers. As the electric field is formed to a higher value as the photoconductor is charged, the resistance in the related layer decreases and the rate of charge retained in the photoconductor is restricted. The potential of the photoconductor in this instance is called acceptor potential which is the important factor to determine the potential contrast. To avoid giving electrical distortion in the photoconductor, charge is normally made to a level slightly lower than the acceptor potential.
· · · · · · · ·
Permits a variety of structures (drum, sheet, belt) Higher insulation in dark area (charge acceptability and retentivity) Permits a variety of molecular structure (allows a variety of molecular design) Light weight Stable against humidity and temperature Safety for environment (non-pollution, unrestrained disposal) Not strong in anti-wear property Not strong against light and ozone.
[Charge retentivity]
The time the static latent image is held by the photoconductor depends on the speed at which the potential decreases in the dark area. For this, measure the time the photoconductor potential abates to a half of the starting value in the dark area. This charge retentivity may cause a problem when the time from the exposure to the development is long. But, it may not be a problem with the machine where a series of operations from charge, exposure, and development are automated and time between processes is shorter.

This is dependent on the attenuation speed of the potential when the photoconductor is exposed to light.
[Residual potential]
When the charged photoconductor is exposed to light, the potential abruptly diminishes at first, then begin decaying relatively slowly. The potential of the photoconductor where slow decay starts is called residual potential. For a less residual potential produces a large potential contrast, low residual charge is preferable. The value of the residual potential affects largely to the development of gradual tone.

If charge and exposure are repeated, the phenomenon called photoconductor fatigue occurs. In other words, it appears as an increase of the decay speed of the photoconductor potential or a decrease in the charge retentivity. Now, we have learned about the characteristics required for charging of the photoconductor. If charge is repeated from the corona unit in the actual operation, the corona wire is likely to be contaminated with dust, stain, and scattered toner, causing uneven corona charge. To avoid this, the corona wire needs to be cleaned well.

2. SD-2060 basic process and structure
·
The Scorotron method is used to evenly charge the photoconductor surface to the given potential in the charge process. The corona wire regularly used is now replaced with a new corona charge mechanism that employs the 0.1mm thick stainless steel saw tooth plate, in order to suppress ozone generated when the oxide molecule in the air is ionized. Considering the service efficiency, the process separation mechanism is adopted.

(1) Details of image forming process
STEP 1. Charging
The main corona creates a negative charge on the OPC drum surface. The surface potential of the OPC drum is controlled by the screen grid voltage to maintain at the potential equal to the grid voltage.

When the drum surface voltage is lower than the screen grid voltage, electric charges from the main corona pass through the screen grid to reach the drum surface and charge it until the drum surface voltage becomes equal to the grid voltage. When the drum surface voltage reaches almost the same level as the grid voltage, electric charges from the main corona flow through the electrode of the screen grid to the high voltage unit grid voltage output circuit, thus maintaining the drum surface voltage at the same level as the grid voltage.
STEP 3. Development (Bias 200V)
The electrostatic latent image on the drum surface is formed into a visible image by the toner. This copier employs the two-component magnetic brush development system, where a bias voltage of 200V is applied to the carrier (MG roller) and the toner is charged positively by friction with the rotating carrier.

STEP 4. Pretransfer
The PTCU positive corona discharge is applied to the drum surface after development to improve transfer efficiency. This weakens the attracting force between the drum and toner, improving transfer efficiency and separation efficiency.
STEP 2. Exposure (Copy lamp, mirror, lens)
The optical image of an original is projected through the mirror and lenses onto the OPC drum surface by the copy lamp. The resistance of the OPC layer reduces in the bright area (light area on the original) to discharge negative charge, forming an electrostatic latent image on the drum surface. In reduction copy, the non-image area of the image is discharged by the BL (blank lamp) before exposure.

STEP 5. Transfer
The visible image on the drum surface is transferred on to the copy paper. A negative charge of the transfer corona is applied to the rear surface of the copy paper to transfer the toner on the drum surface to the copy paper.

STEP 8 . Discharge
The electric resistance of the OPC layer is reduced by radiation from the discharge lamp over the drum to remove residual charges.

Photo mode The photo mode is provided to make clear half-tone copy of the photo originals. In the photo mode, the grid voltage and the copy lamp voltage are lower than in the standard copy mode (the copy density of the black background is lowered) to provide half tone graduations of the copy.
(Dark)
Normal copy mode
STEP 6. Separation
Though the copy paper and the drum are both negatively charged after transfer, the negative potential on the drum is higher than that on the copy paper, generating an attraction force between the drum and the copy paper. To remove the attraction force, AC corona is applied to the copy paper by the separation corona to raise the potential on the copy paper to the same level as the drum surface potential. Resultantly the attraction force is eliminated and the copy paper is separated from the drum. If the paper is not separated from the drum, the separation pawl works to separate it mechanically.

(2) Relationship between the OPC drum and light
The light exposed is absorbed by the charge carrier generation layer (CGL) to generate the charge carrier and moves towards the charge carrier transport layer (CLT). The carrier reached CTL then moves towards the drum surface through CTL to neutralize the surface charge.

In the SD-2060, fall in sensitivity due to long use of the photoconductor drum is corrected by the copy lamp light intensity to prevent against considerable change in copy quality. The drum membrane decrease correction is performed because the drum is affected by the following:

(5) Process Control function
[Summary]
The Process Control function records the density of the standard toner image formed on the photoconductor, and maintains that standard density, thereby ensuring consistent copy quality. This is accomplished by regularly checking the image density on the photoconductor surface and compensating for any deviation from the standard density by varying the MC grid bias voltage output. The exposure is also corrected according to the change in the high voltage output to stabilize the half-tone areas of the copy image.
2 The Process Control Sensor reads the three toner patches and
the bare drum, and uses this ratio to determine the Standard level. (The Standard level is the reference value that must be achieved during Process Control to ensure proper copy quality. This Standard level is preset at the factory and is a result of the value stored in Test Command 44-4).

Note: The value stored in Test Command 44-4 should be 75. In the SD-2060, the absolute value of the Process Control Sensor is not used for control calculation, but the ratio of the sensor output from the bare drum and the sensor output from the toner patch is used. This will allow for correct density compensation when the reflectivity of the drum is affected by dirt or drum deterioration.
Process Control 1 Three toner patches are developed on the photoconductor surface
at three different MC grid bias voltage levels. These three patches are developed using the Photo mode high voltage output calculated the last time Process Control was performed. The voltage values of the three patches are: 1. Photomode voltage (This is the center value and is referred to as Vg (P)) 2. Photomode voltage +50v (Vg (P) +50v) 3. Photomode voltage -50v (Vg (P) -50v)
3 At this time the Standard level is referenced, and three possible
conditions will exist. a If the Standard level falls between the three patch values: The proper MC grid bias voltage is determined in Fig. A.

b If the range of the three developed toner patches is lower than
the Standard level: Two more toner patches are developed with the voltage values of Vg(P)+100v and Vg(P)+150v, as shown in Fig. B. The purpose of developing two more patches is to bring the toner patch range up to the Standard level. If the toner patch range is still not at the Standard level, two more toner patches are developed with the voltage values of Vg(P)+200 and Vg(P)+250. If still another step is required, the toner patches are developed with the voltage values of Vg(P)+300 and Vg(P)+350. If the Standard level is achieved during any of these steps, the proper MC grid bias is determined, and the toner patch process is discontinued. If the Standard level is still not achieved after these four sets of toner patches (1 set of 3 patches and 3 sets of 2 patches), then an F2-35 condition will occur.
4 When the MC grid bias voltage is corrected by the Process Control Sensor, the corresponding light quantity is also calculated to control the copy lamp output. Process Control timing In the SD-2060, Process Control is performed at the following intervals: 1 When the power switch is turned on. 2 When the accumulated copy time reaches 30 minutes. If the timer reaches 30 minutes during copying, Process Control is performed during copying. If the timer reaches 30 minutes after copying, Process control is performed during the next copy preliminary rotation. 3 When the Stand-by time reaches 1 hour. Process control is performed during the next copy preliminary rotation. 4 When Test Command 46 is performed.

The purpose of developing two more patches is to bring the toner patch range down to the Standard level. If the toner patch range is still not at the Standard level, two more toner patches are developed with the voltage values of Vg(P)-200 and Vg(P)250. If still another step is required, two more toner patches are developed with the voltage values of Vg(P)-300 and Vg(P)350. If the Standard level is achieved during any of these steps, the proper MC grid bias is determined, and the toner patch process is discontinued. If the Standard level is still not achieved after these four sets of toner patches (1 set of 3 patches and 3 sets of 2 patches), then an F2-35 condition will occur.

Drum marking
In the SD-2060, a toner patch image is formed in the same position on the photoconductor drum surface to improve the accuracy of the process control. A marking is provided on the drum, and the marking is sensed before forming a toner patch image. If the marking is not sensed, the machine stops its operation and indicates "F2-32" trouble. (This is for Japan/SEC specifications. For the other destinations, the machine does not stop.)

[5] DEVELOPING UNIT
1. Basic theory
(1) Two-component developer
Two component developer consists of toner and carrier, and is usually called developer. The carrier is a media that applies toner to the static latent image on the photoconductor. As the carrier is stirred with the toner, the friction that occurs charges it to positive or negative potential. Because over time, the developer fatigues and affects its characteristics that deteriorates the copy quality, it needs to be replaced at a given period.

(2) Two-component magnetic brush development
A rotary, non-magnetic sleeve is provided over the magnet roller which rotates during the copy cycle. A magnetic brush is formed with the carrier on the sleeve surface by magnetic force, which allows toner to be attracted to the latent electrostatic image on the photoconductor.

Name Developer magnetic roller Magnetic brush is formed with the carrier by a magnetic force. A plate employed to limit the height of the magnetic brush. Carrier within the developing unit is stirred to distribute the toner evenly. The toner fed from the toner hopper is supplied to the stirring unit.

Developer doctor plate
(3) Developing bias voltage
When the photoconductor is exposed to light, the surface potential (voltage) of the photoconductor is not removed completely and remains as a residual potential. Therefore, the toner adhered to the photoconductor by the residual potential creates background in the non-image areas. To prevent this, a voltage of the same charge as the photoconductor surface and which is higher than the residual potential is added to the magnetic roller to avoid the toner from remaining on the photoconductor surface. 3 Developer stirring roller

When the SD-2060 power is turned on, the machine goes into the warmup mode. When the fusing temperature reaches a certain level, the drum drive motor rotates. The developer unit is driven by the main motor via the main drive unit. Ratio of the carrier and the toner within the developing unit is monitored by the toner density sensor as a change in the magnetic transmission rate and the voltage is sent to the analog input line of the CPU of the main board. In the CPU, the input voltage level is monitored and the main motor and the toner motor is controlled until the optimum density is obtained. Then the toner is supplied, transported, and stirred.

[6] PAPER FEED/TRANSPORT SECTION
1. Basic specifications
The SD-2060 employs a paper tray lifting system in each paper feed section to hold a large quantity of papers in a compact space, and an air paper feed system to feed paper, preventing against double feed and/or smudging. If paper of the same size and same weight are set in paper feed trays 1 ~ 3, when paper is emptied from one of the trays, the continuous paper feed function switches automatically to another paper tray. After image transfer,
