1 INTRODUCTION

1.1 General

The MD400 scanner is a resale of the Ricoh IS50

Image scanner. It is available in 120 Volt and

220-240 Volt variants.

It has an embedded SCSI interface port for connection to a VAXstation computer, and a parallel interface port for connection to a

DECstation PC. You must use the appropriate

SCSI or PC interface kit option. The personal computer (PC) interface kit includes the Ricoh

ISI-8 PC interface card which must be installed in the DECstation backplane.

The Ricoh DF60 automatic document feeder (ADF) is available as a separate option.

1.2 Hardware Options

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.

Operation

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

SCANNER

RED off

GREEN on

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:

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.
