2. SAFETY

2.1 Safety Warnings

ELECTRIEL

Do NOT remove this cover from the scanner while it is turned on or operatethe scanner with this cover removed

It is very important to allow the scanner to discharge before removing cover and theboards. The boards can holds a charge and can give a shock if touched.

MECLNIEL

The mechanism that operates the lid and the paper handling assembly cantrap fingers please handle with care

WEIGHTSince the weight of the scanner is approximately 26.5Kg (without the stand, and 34.8kg with thestand) and is recommend a minimum of two people to lift it safely.

ROTATING ROLLERS

The scanner operates two sets of rollers to move the image across the scanner. Theserollers, will grip ties and any other similar articles of clothing, as well as long hair if put nearthe rollers during operation.

EMC Testing

All Colortrac scanners, which includes the SmartLF model, have under gone and conform to EMC

and FCC .The EMC test is carried out to assure that no signals that could cause interference areemitted from the scanner or that no external signal will interfere with the scanner. See back for fullinformation.

NOTE: PLEASE FOLLOW ANTI-STATIC PRECAUTIONS AT ALL

TIMES WHEN HANDLING COLORTRAC AND SmartLF

BOARDS.

3 System Diagram.

3.1 Contact Image Sensor Technology.

The SmartLF scanners differ for the existing Colortrac scanner because instead of using CCD

(Charge Coupled Device) technology, it uses CIS (Contact Image Sensor). This eliminates the needfor ballast boards and tubes. The CIS devices are fitted and aligned in a clean room environmentand can NOT be replaced in the field. Should the CIS fail and need replacing, then the scanner mustbe returned to the Colortrac factory after contacting the Technical Support Department at the

address on page 5. There are 5 CIS devices in every SmartLF at 400dpi each and they connect

directly to the combined main board.

4 How to Replace Boards in the SmartLF

4.1 Opening Access Panel for all boards.

To access any of the boardsthat make up the SmartLF

scanner, the access panel atthe rear of the scanner needs tobe opened as follows:

1 Disconnect Power cable and USB2 cable from the SmartLF scanner.

2 Remove media support brackets (Fig.1.) from the rear of scanner by squeezing two sidestogether and removing, for easier access.

3 Remove the M3 x 10mm screws (Fig.2.) to open access panel for Main boards

4 Lower access panel gently (Fig.3.) to avoid damage to hinges or cables attached to boardsand panel. Check cables are not tight as lowering access panel.

NOTE: Do not open access panel if the glass has been lifted out with ribbon cables attached to CISdevices as shown on page 32.

Fig.1.

4.2 Removing Combined Main Board.

As the Combined Main Board is the only board that controls all operations on the scanner, most ofthe problems will be fixed by changing this board. Colortrac does not offer diagnostic support for anyof the boards and will only replace boards to repair the SmartLF scanners.

1 Open rear access panel as described in “4.1 Opening Access Panel for all Boards” page 8.

2 Disconnect CIS ribbon cables by first, carefully, releasing the locking slide (Fig.4.) and thensliding the cable out from the connector and out through the ferrite held on the panel. Repeatthis to all 5 ribbon cables.

3 Disconnect the power Cable PSU DC O/P from PSU, motor cable (Fig.5.) and display boardribbon cable (Fig.5a.) from the Combined Main Board.

4 Remove the ten M3 x 10mm screws (Fig.6.) and the two M4 x 6mm screws that hold theCombined Main Board on to the panel and gently remove from scanner.

4.3 Inserting Combined Main Board.

Fit the replacement Combined Main Board as follows:

1. Hold replacement board near to panel and insert the ribbon cable for CIS 5 into JP12 of theboard before positioning onto the panel. This is due to the location of the connector (Fig.7a.) andthe difficulty experienced when inserting after the board is in place.

2. Make sure the cable is inserted the correct way around. Fig.8. shows it in-correctly fitted. Theexposed ribbon cores must face away from the locking plate of the connector and must gothrough the ferrite, so therefore the exposed wires is facing TOWARDS you. This is true for ALL5 ribbon cables.

3. Position the Combined Mains Board onto the threaded spacers (Fig.9.) on the panel and insertone of the M3 x 5mm screws into the top central hole to hold into position.

7. If the shim won’t go through the paper hold down, turn the adjustment nut (Fig.116)clockwise to raise the paper hold down until the shim will just go through but at the sametime feel a tension on the shim as pushed through. Move shim back and forth to check that itmoves in and out with a small amount of tension.

8. If the shim goes through the paper hold down without any friction, turn the adjustment nut(Fig.117) clockwise to lower the paper hold down until the shim will still go through but willfeel a tension on the shim as pushed through. Move shim back and forth to check that itmoves in and out with a small amount of tension.

9. Repeat for all the adjustment screws working along the paper guide assembly (Fig.118).Use the same piece of shim between the rollers as in instructions 6, 7 &8 and adjust theassociated adjustment screw. While working along the paper guide assembly it is worthkeep checking back to previous adjustments, to make sure the settings already madehaven’t been moved out, re-adjust if necessary.
