2 INSTALLING THE SYSTEM
2.1 Before Installation
The MD400 hardware and software is customer installable. Digital will install the option for an additional charge.
Before attempting to install the scanner, identify the following:
• All system components for a supported configuration are on site
• A suitable location for siting the scanner/system (Refer to the next paragraph)
• A suitable location for unpacking the equipment.
Check for the following when choosing a suitable location to install the system:
• Scanner shielded from direct sunlight at all times of day
• Scanner away from high temperature, humidity and vibration
• Scanner away from excessive dust or corrosive gases
• Power cord will reach the power outlet, without causing obstruction
• Interface cable will reach the computer, without causing obstruction
• Desk top flat, level, stable and can adequately support weight and size of the scanner and the computer (Refer to Table 4).
The physical characteristics of the scanner and the
ADF are shown in Table 4.

2.2 Installation
1.
Take unopened cartons to the area previously identified for unpacking.
2.
Check packaging for shipping damage and report any damage found.
3.
Unpack and check for short shipments (refer to IS50/DF60 User Manuals).
4.
Retain packing materials. These will be needed for service.
5.
Place equipment in the location previously prepared for installation.
6 MD400 Scanner Pocket Service Guide
6.
Read the installation procedures in the
IS50/DF60 User Manuals.
NOTE
The power cord is shipped as a separate line item, not with the scanner (as shown in the IS50 User Manual).
7.
VAXstation users should halt the system and use the console command:-
>>> SHOW DEVICES to display the current status of SCSI IDs.
Determine and note a suitable SCSI ID for the scanner; an ID of zero is recommended if available.
8.
Switch off the power to the system box and all peripherals.
WARNING
Before connecting or disconnecting interface cables, remove power from the scanner, the host computer and any other devices connected to the SCSI bus.
WARNING
A special interface cable is supplied in the PC interface kit. Do not use any other cable for this purpose as this may severely damage equipment.
9.
Install the interface kit to connect the computer to the scanner as follows:
• VAXstation - I/F cables and terminator, refer to the 3100 User Manual.
• DECstation - I/F card and cable, refer to the ISI-8 Installation Manual.

10. Set the DIP switch on the rear panel as shown in Figure 1.
NOTE
Use DIP switches 6,7 & 8 to select the
SCSI ID previously noted.
11. Install the ADF if required (refer to DF60
User Manual).
CAUTION
Remember to unlock the carriage lock on the scanner.
12. Power up the scanner and check the self-test completes successfully. The indicators light as shown in Table 5 for successful completion.
Table 5 Indicators

13. If indicators are lit as in step 12 the hardware installation is complete. Go to step 15.
8 MD400 Scanner Pocket Service Guide
14. Switch the power off. Check that the installation has been carried out correctly.
Repeat or check steps 8 to 12.
If there is still an error, refer to Section 3.
15. Install the software if required (refer to the
ProImage or DSS manuals).
2.3 Post-Installation Checks - Verification
When the hardware and software has been installed, it is recommended that a document is scanned to check the system is functioning correctly. Beware that image defects in printed hardcopy may be due to limitations of the printer rather than the scanner.
If the performance of the printer is in doubt, use a VDU output device to check the quality of a scanned image. Ask the customer to perform the scan, or refer to the DSS or ProImage Software
User Manuals for help.
Ask the customer to retain the original shipping packaging on site. Explain that it is the user’s responsibility to carry out preventive maintenance and lamp replacement and point out these details in the Users Manuals.
3 TROUBLESHOOTING
3.1 VAXstation Software
DECimage Scan Software (DSS) is a fully Digital supported software product. Refer to the relevant product service documentation.
3.2 PC Software
ProImage is supported directly by the vendor,
Software Dynamics GmbH. The vendor provides a registration card which the user must complete and return to the vendor. This permits the user to contact the vendor by telephone or FAX and get help with ProImage software:

(local time) Monday to Friday
3.3 Shading Correction
If the symptoms are uneven shading, cycle the power on/off and re-scan.
NOTE
It is necessary for the scanner power to be periodically cycled in order for the correction to be fully effective.
The MD400 incorporates shading correction to compensate for the effects of:
• Uneven illumination
• Uneven sensitivity of CCD elements
• Uneven lens characteristics
• Effects of ageing.
The correction is done by using data stored in a correction memory. Data is automatically acquired in the correction memory on power-up, by reading a plain white tape which is built into the scanner.
3.4 Hardware Service Strategy
Localise the fault using built-in tests and replace the defective field replaceable unit (FRU). Refer to
Section 4 for the FRU list.
10 MD400 Scanner Pocket Service Guide
3.5 Service Features
• Indicators: Red and Green on the scanner front panel. Green on ADF. Each indicator can show three conditions: on, off, blink.
• DIP switches: Located on the rear panel (refer to IS50 User Manual).
• Built-in tests:
• Self-tests
• Unit diagnostics.
3.6 Self-Tests
The Self-Test is invoked at power-on. A lamp test is performed during the time that the self-tests are running; the indicators are switched on for approximately 4 seconds.
If the lamp test fails, check the electrical supply and follow the troubleshooting procedure in the
IS50 User Manual.
At completion of the self-tests or if an error is detected during normal operation, the indicators display the error as follows as shown in Table 6.
The indicator display are those at completion of the self-tests or errors encountered during normal operation.

5 TECHNICAL TIPS
Appearance of SCSI scanner to a workstation
>>> SHOW DEVICE
VMS ULTRIX
JKA0: ... A/1/0/00 SCAN xxGB FX IS50
The device will appear as ‘‘JKB0:’’ on dual SCSI machines. The ‘‘capacity’’ field ( xxGB above) changes depending on bus configuration.
The relevant part of the ‘‘test 50’’ screen is:
SCSI-A 0E0E.0001 V1.3
FFFFFF05 06000001 00000001 00000001
FFFFFF05 FFFFFF05 FFFFFF03 FFFFFF05
5.1 Voltage Selection
The difference between MD400-AA and MD400-A3 is the internal switch setting on the power supply.
Do not change this.
18 MD400 Scanner Pocket Service Guide
5.2 Limitations of SCSI Configurations
There is a limitation on the length of cable which may be used to connect SCSI devices.
The maximum allowed length is 6 metres, which includes bus stub lengths within the expansion boxes. In order to meet this requirement, the total length of cable on a single SCSI bus should not exceed 4 metres.
6 FURTHER INFORMATION AND HELP
Further MD400 information is in the MD400 PSP,
PASS record 5734 and ProImage PSP, PASS record
3049. The Support organisation have access to a detailed level of product information. Please contact your local centre for help.
