Figure 1.4 shows the system block diagram.

The main control board controls all the modules built up the OptraImage 443. It includes a RISC. ARM7as the main controller, two Flash Memory as program area and one EDO RAM as working space, one89C52 for panel control, two ASIC for flatbed and ADF image processing and each have external 32MBSRDRAM for data processing, two A/D converter for processing flatbed and ADF CCD signals input, twosets of motor drivers for driving flatbed and ADF motors, two SCSI controller for data interfacing withhost and printer.

The power is an external 24V/2500mA power adapter for the whole system. There are some differentvalues inside the OptraImage 443:

+24V Power directly comes from the power adapter and used for flatbed and ADF motor.

+12V Power converted from 7812 to supply flatbed and ADF CCD

+5V Power converted from 34063 to supply 89C52, SCSI controller and some 5V logic.

+5V Power converted from 7805 to supply flatbed and ADF A/D converters and all analog circuit.

The video noise suppression circuit is to eliminate the reset noise and low frequency noise of CCD andthen PGA performs video gain control. The “level shift” circuit is used to bias the PGA output tosatisfy the reference bottom requirement of the A/D converter. The “DC-OFFSET Adjust” circuit is usedto adjust the bias level of video signal.

1. If there is already another device linked to the host via SCSI cable, remove the terminator from thatdevice. If the terminator can not be removed, it is recommended that the connection of Configuration Ibe used.

2. Set scanner’s SCSI terminator switch on.3. Plug one end of the SCSI cable to one female connector of the previous device or the host.

SCSI specifications require that:

1. Only one terminator may be attached to each end of the daisy chain.

2. The total length of the daisy chain must not exceed 6 meters. The vendor suggests that the SCSI cable betwo or three meters in length to allow other devices to be attached to the SCSI bus.

3. Each device on the chain will be assigned a different ID. Devices with the same SCSI ID will cause themto malfunction.

4. There is no restriction on the position of the devices on the daisy chain.

2.52.52.52.5 SCSI ID SettingSCSI ID SettingSCSI ID SettingSCSI ID Setting

When you have several devices on a SCSI chain, you may need to adjust the SCSI ID selector setting locatedon the back of the scanner (See Figure 2-3). The SCSI ID selector is a dip switch allowing you to assignan unique ID number from 0 to 7. If the ID number is duplicated with an existing SCSI device, the scannermay not work properly.

Note that the scanner contains two SCSI devices. One is the scanning unit itself, the other is the controlpanel on the front of the scanner. The SCSI ID selector for the scanning unit located at the left sidewhile the SCSI ID selector for the control panel located at the right side.

1. SCSI ID # selector of the scanning unit (factory setting: 6)

2. Terminator ON/OFF Switch (factory setting: ON)

3. SCSI ID # selector of the control panel (factory setting: 0)

Refer to the following table for various status indicating the different ID numbers.

3.2 TroubleshootingTroubleshootingTroubleshootingTroubleshooting

This chapter describes two methods to solve the operational problems. The first relies on the OptraImage443’s internal diagnostics. The second uses troubleshooting flowcharts and tables to isolate the problem. Inmany cases, the internal diagnostics will help you to locate the source of the problem quickly. Use thesediagnostics first. If the diagnostics do not locate the source of the problem, refer to Section 3.2TroubleshootingTroubleshootingTroubleshootingTroubleshooting.

4.4 Spare Parts Replacement

This section describes the spare parts replacement procedures. Depending on the part, adjustment orlubrication may be necessary, but this will be described in Section 4.7.

4.4.14.4.14.4.14.4.1 Notes on ReplacementNotes on ReplacementNotes on ReplacementNotes on Replacement1. Clean the disassembly and assembly location.2. Turn off the power switch and remove the AC plug from the outlet before disassembly and assembly.3. Follow the disassembly and assembly procedures. Never loosen the screws of parts that must not be disassembled.4. Store the disassembled parts in a clean place to avoid loss.5. After replacement, check the contacts and spare part mounting.6. Assemble in the reverse order of disassembly.

After scanning approximately 100,000 pages through the ADF, the ADF pad module may be wornout and you may experience problems with document feeding. In this case, please replace theADF pad module with a new one. For ordering the parts, please consult your nearest dealer andfollow the procedure below to replace it.

To remove the ADF snap-in pad module,

1. Push the ADF unit backward.2. Use your fingers to gently pull out the snap-in pad module.

Figure 4.13 ADF Snap-in Pad Module Removal

To mount the ADF snap-in module,

1. Use your fingers to hold both arms of the snap-in pad module.2. Gently place the snap-in pad module into the pad holder. (See Figure 4.13)

4.5 PCBA Voltage Test

This chapter describes how to check parts for proper voltage levels.

4.5.14.5.14.5.14.5.1 Check power supply output voltageCheck power supply output voltageCheck power supply output voltageCheck power supply output voltage

Tool: DMM (Digital Multi Meter)

Procedure:

1. Loosen the screws on the main PCBA cover. Remove the metallic plate underneath the PCBA, but keepeach cable connected.

2. Turn on the scanner.3. Check the voltage level of each pin of J10 connector on right side of the main control PCBA. The

specified voltage level for each pin of J10 is as follows:

Pin #14: +24VDCPin #13: 24VGNDPin #4: +5VDCPin #3: GND

4.5.24.5.24.5.24.5.2 Main control PCBA input power (+5V) failure checkMain control PCBA input power (+5V) failure checkMain control PCBA input power (+5V) failure checkMain control PCBA input power (+5V) failure check

Refer to the procedure above. (subsection 4.6.1)

4.5.34.5.34.5.34.5.3 LED display PCBA checkLED display PCBA checkLED display PCBA checkLED display PCBA check

Tool: DMM (Digital Multi Meter)

Notice:1. There is a 15-pin connector connects to the ADF motor board where there are three pins connected to

the LED board as follows:Pin #14: 24VDCPin #15: 24VGNDPin #5: Yellow LEDPin #6: Green LED

Pin#7: Red LED

4-27

2. The turn-on method for each LED are listed below:The Yellow LED: Turn on the scanner.The Green LED: Turn on the scanner and wait for the scanner to get ready.The Red LED: Turn on the scanner and wait for the scanner to get ready. Then push the paper-insensor on the ADF. Three seconds later the paper-in scanner will turn the ADF motor. Keep holdingthis sensor. A few minutes later the scanner will stop turning the ADF motor, and then the Jam LEDwill be on. Remember to keep holding the sensor.

3. As described above, if the corresponding LED remains off, follow the procedures below to locate theerror.

i. Check the LED cable connection.ii. Check the LED cable for any broken wires.iii. Check the voltage level at the connector. The correct voltage levels for LED’s ON/OFF are listed

below:LED ON 2.4VLED OFF 5.0V

iv. If voltage levels are correct, replace the LED board.
