`
`Radio frequency interference
`
`This equipment has been designed for compliance with FCC Part 15 Subpart J, Class A and VDE 0871 Class B
`requirements. The equipment has also been designed in compliance with the German Zentralamt fuer Zulassungen
`im Fernmeldewesen (ZZF) regulations Vfg 1046 and is radio interference suppressed.
`
`The equipment incorporates various design features to minimise both conducted and radiated emissions. In the case
`of radio or TV interference, the following points should be checked and corrected where necessary:
`
`(i)
`
`Control and data interface cables as supplied use shielded cable and connectors, and have ferrite beads for
`(ii)
`additional protection against unwanted radiation. User-supplied cables need to be similarly constructed if interference
`is to be minimised.
`
`Experience has shown that in the majority of instances, the host PC is the predominant radiator of
`(iii)
`interference. In critical installations, care should be taken to select a model which is qualified to FCC/VDE standards.
`
`The siting of the radio/TV receiver and/or its antenna should be carried out so as to maximise the wanted
`(iv)
`signal and minimise interference.
`
`If the radio/TV receiver is mains powered, it is advisable to use a separate AC socket outlet from that used for
`(v)
`the aperture card equipment.
`
`The equipment must be serviced only by qualified personnel, as otherwise repairs could be made which
`(vi)
`appear to work but which lead to excessive interference.
`
`WARNING: This equipment generates, uses, and can radiate radio frequency energy and if not installed and
`used in accordance with the instructions manual, may cause interference to radio communications. It has
`been designed to meet the limits for a Class A computing device pursuant to Subpart J of part 15 of FCC
`Rules, which are designed to provide reasonable protection against such interference when operated in a
`commercial environment. Operation of this equipment in a residential area is likely to cause interference, in
`which case the user at his own expense will be required to take whatever measures may be required to
`correct the interference.

`Introduction
`
`
`
`
`1.1 General description
`
`The 5100 Scanstation and the SCANFICHE operating software provide easy and reliable operation when producing
`raster image data from fiche.
`
`
`Figure 1.1a - The 5100 Scanner
`
`
`
`
`The system provides all the facilities needed to scan, print or do both from microfiche or jackets and create image files
`of the best possible quality. The 5100 Scanstation is a table-top machine which is operated by a PC controller
`running Wicks and Wilson SCANFICHE software. The 5100 Scanstation is delivered with the interfacing cable and
`PC interface card but the provision of the PC Controller itself is the responsibility of the user. The software uses the
`Windows NT operating system and can display and output files in compressed raster format, directly over the user's
`network system. Alternatively the Scanstation can operate as a local scanner, generating image files on the PC
`Controller's own internal hard disk for subsequent quality assurance before being transferred to another system.
`
`The Model 5100 can produce output file resolutions between 200 and 400 dpi at a speed of up to 75 frames per
`minute. The frames may be located on the film either by their edge or by absolute positioning. All the necessary
`controls and functions are provided so that scanning can be performed automatically, requiring operator intervention
`only when loading and unloading cassettes of fiche. Operation is simple and is started by loading a cassette loaded
`with a fiche into the load station.
`Scanning is started by clicking the "SCAN" button in the run-time scanning window. The fiche is automatically
`transported for the frames to be scanned.
`A powerful viewing facility, which operates during the scan, allows the user to check the quality of the scanned images
`prior to committing them as files to a document management system or other system directory. The scanner cabinet

`
`
`contains all the power supplies and electronics and provides full RFI and safety screening. Figure 1.1a on page 8
`shows the main mechanical features of the 5100 Scanstation.
`
`
`
`
`
`1.2 Using this field service manual
`
`This manual should be used in conjunction with the 5100 Scanstation User's Guide (Part number 8100021 so that
`there is a full understanding of the function of the machine and its features and the 5100 Parts Manual (Part number
`8100023) which contains all the assembly drawings and circuit diagrams relevant to this range of scanners and is
`essential when using this field service manual.
`
`The purpose of this manual is to enable qualified field service technicians to undertake setting and maintenance
`operations, as they become necessary. Although the details given in this manual are comprehensive, it is still
`considered necessary for all field service technicians to take part in an approved training course.
`
`1.3 Machine safety features
`
` A
`
` danger exists from the mechanical movement of parts inside the machine, and this occurs during the normal
`operation of the machine. Care should be taken to prevent fingers and hair from being trapped in moving parts -
`particularly in the film loading area.
`
`The scanner is enclosed by a front and a rear metal cover which may only be removed by qualified service
`technicians. Removal of these covers gives access to the motors and mechanisms. Service technicians should take
`great care when servicing the machine to avoid touching any of the rotating parts or any electrical connections. The
`electrical power danger relates to the supply voltage entering the machine from the power source - all the control
`circuits in the machine operate at a maximum rated voltage of 24VDC.
`
`1.4 The scanner power supply
`
`The 5100 scanner is fitted with an auto-ranging power supply which will operate correctly without adjustment over the
`supply voltage range of 90VAC to 250VAC and 50Hz to 60Hz. The current will vary from 2.0A to 0.8A over the same
`range.
`
`1.5 Power Cord
`
`This machine must only be operated with a power cord of the correct type, which complies with any applicable local
`regulations. Suitable types are normally Type 'SO' for USA or type 'HAR' for Europe. Only use a recognised
`CERAMIC fuse (European IEC 127 or North American (UL/CSA)) type T3.15A 250 VAC in the mains supply plug.
`
`1.6 Power supply and environmental requirements
`
`The environmental specifications for the scanner are as follows:
`Supply voltage
`
`
`90 to 240 volts
`3.15 amps
`Running current
`
`Supply frequency
`
`50 to 60 Hertz
`Operating temperature 15 to 27°C
`Operating humidity
`
`40 to 60% (non condensing)
`
`For the environmental requirements of the PC controller refer to the literature provided with the PC.
`
`1.7 Scanner safety features and override facilities
`
`All the internal accessible voltages are extra safe low voltage DC supplies and all the mechanical moving parts are low
`speed and low torque. The light source is a series of 30 light emitting diodes (LEDs) which are of no hazard to the
`naked eye. There is a safety cut out (SW2) to prevent objects or parts of the body being trapped by the loading of the
`fiche cartridge.
`
`1.8
`
`Attention is expressly drawn the to following warnings which also appear elsewhere in this User’s Guide in
`the sections which relate to them.
`
` General Safety Warnings
`
`1. Take care with live parts - If the machine does not need to be running, always remove the power plug from the
`socket before working on the machine.
`
`2. Be careful that hair, fingers, jewellery and clothing do not fall into or get caught in the machine.

`

`
`
`
`
`3.
`
`In service activities take care with all moving parts such as drive wheels, gear wheels and toothed belts which can
`cause serious injuries. Extra care should be taken during the start-up phase as the machine may start running
`during initialisation.
`
`Page 9
`
`
`4. Keep the wall mounted socket outlet or power switch easily accessible.
`
`5. This equipment is not suitable for connection to an IT-power system, often used in stand-alone power systems (for
`instance off-shore rigs, and mining). When in doubt consult your supplier.
`
`6. Be careful to observe the power ON/OFF switch markings. 'I' is ON and 'O' is OFF. When the power is ON a
`green LED close to the switch is illuminated.
`
`7. A blown fuse does not guarantee a powerless situation. Replace the fuse only with a recognised European IEC
`127 or North American (UL/CSA) CERAMIC fuse type T3.15A 250 VAC. Failure to do so may result in fire or
`damage to the equipment.
`
`8. When replacing a power cord or power plug, only use components which comply with local regulations. Only use
`a power cord of the correct type, e.g. 'SO' type for USA or 'HAR' type for Europe.
`
`9. Only connect the scanner to the computer with the Wicks and Wilson Data Cable supplied with the scanner
`(W&WL Part No. 8008009)

`Technical description and theory of operation
`
`
`
`
`2.1 Functional description - mechanical and optical
`
`2.1.1 The Power Supply Unit (PSU)
`The PSU is self regulating, with an input voltage range of 99 to 264 volts. Supply to the PSU is via the mains input
`socket/filter (PL1) and through the mains switch (SW1). There is an output voltage adjustment on the +5volts supply.
`See Section 4.1.5 for setting instructions. The POWER ON LED adjacent to the mains switch indicates when the
`machine is switched on.
`
`2.1.2 Operation
`The mode of operation is selected by commands sent to the scanner by the software. When the machine is first
`switched on a simple run-time display is presented to the user on the controller PC. Selection of other features and
`functionality are achieved by a series of pull down menus from the Windows menu bar.
`
`All the necessary controls and functions are provided so that scanning can be performed automatically, requiring
`operator intervention only when loading and unloading rolls of film. Operation is simple and is started by loading a
`cassette containing fiche onto the loading station. Scanning is started by clicking the "SCAN" button (the green PLAY
`arrow on the tool bar) in the run-time scanning window. The frames are scanned until the complete film has been
`scanned or the machine is stopped. A full description of the use and operation of the software feature and facilities is
`described in the 5100 User's Guide (Part number 8100021).
`
`
`
`Figure 2.1a - Main run-time display screen
`
`As the image is being scanned, the data is sent to the SCANFICHE software, which drives the image display system
`and provides data compression and file formatting. The data is converted to complete image files, which are then
`placed in the required data directory using the network interface. Figure 2.1a on page 14 shows the monitor main
`display, before starting the scanning operation.
`
`After the frame has been scanned, it may be retained in the scanning position or it may be accepted or rejected
`depending upon whether ASSISTED, BATCH AUTO, BATCH CHECK or MANUAL scanning mode has been selected.
`The next frame may be scanned by using the appropriate command buttons. The full operation of the Scanstation is
`described in the User's Guide.

`
`
`
`
`2.2 The optical scanning system
`
`There are two optical scanning modes, Speed (35mm) and Quality (16mm). The user is able to set either of these two
`modes depending upon the reduction ratio, dpi and the height of each image to be scanned. For instance, 24x, 200
`dpi and a height of each image being 24mm would result in the user being able to select Speed mode only. A 42x,
`200 dpi and a height of each image being 7mm would result in the user being able to select either Speed or Quality
`mode. To summarise, if the height of each image is above 16mm then you cannot use Quality mode.

`
`2.2.1 The Illuminating LEDs
`A 30 LED illuminator mounted on Card 493 generates the light. The output of these LEDs is variable within the
`System Configuration setting of the SCANFICHE software.
`
`2.2.2 The Diffuser
`There is a diffuser between the illuminator and the first perspex lens to diffuse light from the illuminator.
`
`2.2.3 The Fiche Film Cartridge
`The fiche film cartridges are provided to give easy transport of each microfiche and provide accurate referencing of the
`film within the machine. They also cut down on problems of any static charge picked up by the fiche.
`
`2.2.4 The Motorised Main Lens
`After passing through the film the light is collected and focused by the main lens onto the CCD. The light is focused
`onto the CCD via a 45° mirror either in speed mode, directly onto the CCD, or in quality mode via the 16mm mirror
`assembly. The main lens is motorised, providing accurate focusing of the optical system. The lens is permanently set
`at an F stop of F5.6 and does not require alteration for any purpose and there is no focus ring on the lens itself.
`Section 4.3 provides full instructions on focusing the machine.
`
`2.2.5 The 16mm Mirror Assembly
`The 16mm mirror assembly is motorised and is driven into or out of the optical path depending on whether Speed or
`Quality mode are selected.
`
`2.2.6 The Camera Card
`The position of the camera card holding the CCD is adjustable in angle and along the optical axis to provide fine focus
`adjustment. In the adjustment procedure described in section 4.3, focus adjustment is first made by means of moving
`the main lens followed by a fine focus procedure using the CCD position. The run-time system provides a procedure
`for performing coarse focus and the fine focus adjustments using real images viewed on the screen.
`

`
`The input stages of the video circuits are isolated from the motor and actuator circuits to minimise noise interference
`on the image data. The PC Interface Card 478 provides part of the video processing and also the interfacing of the
`imaging and control system into the controller. A single interface cable connects the scanner to the PC controller card
`through a single connector containing a quad RS232 command interface and a proprietary video signal interface.
`
`2.3.1 The Differential Cable Driver Card 471
`This card is the termination inside the scanner of the cable, which interfaces the scanner to the PC controller. There
`are no links or switch settings on the Card 471.
`
`2.3.2 The SMARTSCAN 7 image processing Card 475
`This card provides high speed processing of the image data using 256 (8 bit) grey levels throughout. Links 2 and 4
`must be fitted.
`
`2.3.3. PC Interface Card 478
`The PC interface is Card 478, which uses the PCI interface bus. The card provides the following functionality:
`
`
`1 Block transfer of data to the PC (using fast bus master transfer mode.)
`2 Control of RS232 information.
`
`
`Data from the video processor card is provided in the form of 4-bit nibbles, each containing four packed pixels of
`thresholded data. These four lines are provided together with a CLOCK LINE and PAGE signal to the 37-way input
`connector to Card 478. On board Card 478 the image data is first repackaged into 8-bit bytes and then buffered into a
`FIFO buffer chip. Data is transferred into PC main memory in blocks of 512Kb. Control of the FIFO buffer is by
`FPGA . The PCI interface is controlled by a proprietary chipset. There are no IRQ hardware interrupt settings used
`in the SCANFICHE software. There are no links or switch settings on the Card 478.
`
`2.3.4 CCD Camera Card 490
`This card provides the mount for the CCD linear array and the clocking, buffering and interfacing functions for the
`image data which they generate. This video data is provided as a digital signal into the SMARTSCAN 7 image
`processing Card 475.
`
`The camera card is mounted on a series of brackets that provide rigidity and at the same time adjustment of the CCD
`in three axes. The whole card plus the CCD can be moved along the optical axis by a small amount to obtain the
`optimum focus. This is achieved by mounting the card on a bracket, which hinges at one side of the chassis. In
`addition, the whole card may also be tilted so that the CCD can be made orthogonal to the optical axis to obtain the
`same focus at both ends of the image (top and bottom of the fiche). This is achieved by mounting the card onto a
`strong bar, which may be rotated about one end. Lastly, the whole card may be rotated slightly about the centre of
`the CCD in the plane of the CCD so that the line of scan may be made perpendicular to the direction of scan. The
`CCD and its socket are mounted on what is normally the solder side of the PCB and a support pillar is provided for the
`PCB right next to the CCD mount to eliminate any effects on focus due to any mechanical movement of the PCB or
`framework. There is a potentiometer mounted on the camera card, which is used to set up the video system as
`described in Section 4.2.
`
`Z Stepper Motor MT3
`2.3.4.1
`The Z stepper motor is driven from the CCD Camera Card at HP325. It controls the position of the motorised focusing
`lens, which provides focusing in both Speed and Quality modes.
`
`
`
`2.3.4.2 Card 261 Z Home Sensor
`This sensor provides an accurate home position of the motorised focusing lens at initialisation.
`
`
`
`2.2.5 The Controller Card 492
`This card receives the controlling commands from the SCANFICHE software via the PC interface Card 478 and the
`interfacing cable. It also contains an interface to the Illuminator Card 493.

`
`2.2.5.1 Scan motor (MT1)
`The scan motor is a stepper motor driven normally using 400 steps per turn. When scanning the distance between
`scan lines is determined by the velocity of the fiche across the imaging plane. This is set up by software commands
`sent to the firmware prior to each scan according to the imaging parameters required. The software sends a
`command which determines the distance to the start of the image, image length and velocity for scanning and the
`firmware creates the correct velocity profile for the scan motor so that it slews quickly to the start of the image and
`translates the field at an accurately defined velocity over the image area. A signal is given to the CCD camera card
`just prior to starting to scan the active image area, which initialises the collection of data from the camera card and
`processing of data prior to output to the PC interface Card 478. During imaging, data is clocked from the CCD at a
`constant clock and line rate which is independent of the reduction ratio and resolution currently set. On completion of
`a scan, transmission of image data ceases and the scan motor decelerates to a stop.
`
`When in fast move a second mode is used for slewing a fixed distance. In this case, a firmware command indicates
`the distance to be moved and the processor on the card controls the scan motor to move that distance in the shortest
`time. A third mode, which is used for finding the edge of the image, uses a firmware command to set the scan motor
`into continuous run until the uncovering of the edge of the frame. In all modes, a direction command to the firmware
`sets the direction in which the motor will turn.
`
`2.3.5.2 Other sensor and drive functions on the Controller Card 492
`The following sensor and driver connections are also interfaced by the Controller Card 492 into the PC controller and
`SCANFICHE software:
`
`
`1 Y Stepper Motor (MT2) control.
`2 Y Home Sensor (S2)
`3
`Input Hopper Motor (MT4) control
`4 Exit Hopper Motor (MT5) control
`5
`Illuminator brightness. The SCANFICHE software adjusts the brightness of the Illuminator by sending
`commands to this circuit, which then controls the Illuminator Card 493
