Pay attention to the following matters before unpacking and installation.

Do not install in a place where vibration may occur.

Keep the DM3220 out of direct sunlight. Do not install near a heat source.

Do not place the DM3220 around materials which shut off the circulation of air.

Do not install in a humid or dusty place.

Use care not to scratch the glass surface of the DM3220 or the document holding pad with a clip or staple.

Do not use the wall socket with connecting devices which may generate noise, for example, air-conditioner, etc.

Use a suitable AC power source.

Place the DM3220 on a level surface.

3-2

3.2 TRANSPORTATION

To move the DM3220 from where it is installed, for repair or any other reason, make sure to observe the following conditions:

(1) Turn off the power of the DM3220.

If the scanning head is located at a place other than the home position, turn the DM3220 on to return the scanning head to the home position. Before making sure the scanning head is returned to the home position, turn the power supply off.

(2) Move the lock switch to the “lock” position.

(3) Remove the power cable.

(4) Put the DM3220 in the packing case with the packing material.

4. THEORY OF OPERATION

Introduction

Main Control Unit

4.1 INTRODUCTION

Figure 4.1 Theory of formation of image.

The reflected rays of your original as shown in the above Figure 4.1 pass through the lens and create an image on the CIS. Then, according to the different light intensity perceived by the CIS, the CIS will transfer these data into a series of analog signals to the main board, where the signals are turned into digital signals. These digital signals flow to the USB 2.0 Controller to transfer to a host computer.

5. PROBLEM SOLVING

5.1 Diagnostics 5.2 Troubleshooting

This chapter supplies two paths for dealing with operational problems. The first relies on the scanner’s internal diagnostics. The second uses troubleshooting flowcharts and tables to isolate the problem. In many cases, the internal diagnostics will help you to locate the source of the problem quickly. Use these diagnostics first. If the diagnostics do not locate the source of the problem, refer to Section 5.2 Troubleshooting.

5.1 DIAGNOSTICS

The scanner has internal diagnostics to help you determine the cause of operational problems. Some of the diagnostics function with the scanner online, while others are part of a separate offline diagnostics feature.

5.1.1 ONLINE DIAGNOSTICS

Determine operational problems by observing the display panel and check the LED. With the scanner online and operating normally, the LED is on. Other LED indications is described in the following table.

Long Blinking Off Off Sleeping Mode

Off Blinking Refer to table 5-2 Group Error

Table 5.1 Online diagnostics

When power on, each of the two 7-segment LEDs is lighted with “PP” and is loading code.

When the machine starts, each of the two 7-segment LEDs is lighted for 0.3 seconds in turn until the system gets ready.

When the machine starts, the blue LED blinks. The frequency is shown below:

If there is a problem, the red LED blinks. The LED blinks in turn to indicate various error codes, which one can use to debug the machine. The two 7-segment LEDs also indicate error codes, as shown below:

For example: Error code 4

The Red LED indicates:

The two 7-segment LEDs indicate:

The Blue LED blinks longer during the sleeping mode.

If the ADF cover is open, close it. For the group errors, see the flowcharts later in this section.

5.1.2 OFFLINE DIAGNOSTICS

To run the offline diagnostics, and turn the power back on. When you first turn the scanner back on, the LED light will blink, indicating that the diagnostics are in progress. Observe the front panel LED closely. In a short time, the LED indicates the results of the offline diagnostics as explained in the table below.
