Background

To upgrade a ThermoFlex Mid/Narrow S or F to ThermoFlex Mid/Narrow V-speed, you must replace the L-box.

Requirements

• Upgrade Kit
  • Mid—part number 015-00344A
  • Narrow—part number 015-00343A
• Trolley for lifting the L-box
• Jig (part number 291A3L006)

Procedure

This procedure contains the following sections:

• Removing the L-box
• Installing the upgraded L-box
• Updating software parameters

Removing the L-box

1. In Controller, send the carriage to the middle position.
2. In Controller, open the relevant door(s) to enable access to the carriage, and open the unload tray if required.
   Note: On some of the older models, you must remove the unload tray by removing the four screws.
3. Remove the two hex screws that secure the oil bracket to the carriage and remove the oil bracket.
   
4. Insert a motor cheater, and then send the carriage to EP.
5. Exit the application, turn off the device, and disconnect the power supply from the wall socket.
6. Open the rear door, the front door, the side doors and the rear panels of the device, as required.
7. Remove the two screws that connect the chain to the mainframe (at the end of the chain on the underside).
   
8. Cut the cable ties that hold the debris removal tubes, the fiber optic threads, and the anti-collision fibers.
9. From the Local mother board, disconnect the focus and resolution motors' connector.
   
10. Remove the Philips^® screw from the flange that secures the fiber optics tube and the debris removal tube.
    
11. Remove the two hex screws that secure the L-box and pull the L-box slightly out.
    
12. From the L-box, disconnect the TSP cable connector and the E-box cable connector.
13. Remove the 11 screws that secure the L-box to the frame.
    Warning: When the screws are removed, the L-box rests on a platform and is not secured by anything.
    
14. Carefully pull the L-box out about one meter from its position in the device, slide a trolley under the L-box, raise the trolley until it touches the L-box, and then slowly pull the L-Box out until it is on the trolley.
    
15. Remove the local board.
16. With the special hex key, remove the three hex screws that secure the lead screw coupling to the carriage.
    
17. Disconnect the following:
    • Stepper connector
    • Fine and coarse stepper detectors
    • Ground cable
    
18. Remove the four hex screws that secure the house bearing, and pull out the leadscrew.
    
19. Remove the carriage, including all wiring.

Note: When you have completed the procedure, pack the L-box in the upgraded L-box package, and return the old L-Box to Billerica Shipping and Receiving. If you do not have an RMA number, reference the SP number.

Installing the upgraded L-box

1. Unpack the new L-box, put the new L-Box and head on the trolley, and move them close to the Thermoflex. Raise the trolley to bring the L-Box to the proper height to be secured to the chassis.
2. Place the carriage on the beam.
3. Insert the jig into the leadscrew coupling, as shown, with the jig in the hole that is parallel to the flat side of the coupling.
   
4. Make sure that the jig is in the bottom hole, and insert the leadscrew.
   Note: The placement of the jig in the bottom hole ensures that the leadscrew is inserted in the proper location.
   
5. With the special hex key, tighten the two hex screws that secure the leadcrew coupling to the carriage.
6. Remove the jig from the leadscrew assembly, and tighten the third hex screw that secure the leadscrew coupling to the carriage.
7. Insert and tighten the four hex screws that secure the house bearing.
8. Connect the following:
   • Stepper connector
   • Fine and coarse stepper detectors
   • Ground cable
9. Insert the upgraded L-box into the device.
10. Secure the L-box to the frame with the 11 screws you removed earlier in step 13.
11. Connect the TSP and E-box cable connectors to the L-box.
12. Insert and tighten the two hex screws that secure the L-box.
13. Insert and tighten the Philips screw in the flange that secures the fiber optics tube and the debris removal tube.
14. Connect the focus and resolution motors' connector to the local mother board.
15. Secure the debris removal tubes, the fiber optic threads, and the anti-collision fibers in place with cable ties.
16. Insert and tighten the two screws that connect the chain to the mainframe.
17. Insert and tighten the three hex screws that secure the lead screw coupling to the carriage.
18. Connect the power supply to the wall socket.
19. Close (or install) the unload tray.
20. Close the rear panels and all the doors of the device.
21. Turn on the platesetter.

Updating software parameters

After you complete the hardware upgrade, you must change some of the parameters, described following.

1. In the registry, select HKEY_LOCAL_MACHINE\SOFTWARE\Scitex\ Projects\LOTEMFLEXO\IO OBJECTS\LASER GROUP\Laser Group and change the Max Possible Laser Power parameter from 610 to 900.
2. In the registry, select HKEY_LOCAL_MACHINE\SOFTWARE\Scitex \Projects\LOTEMFLEXO\IO OBJECTS\NEW LOCAL \LDT\Light Detector and change the following parameters:
• High Dac Factor—3.5 or less
• Low Dac Factor—3.5 or less

Note: The following are the maximum drum speed possibilities that exist in the V-speed configuration for Mid devices:

3. If the number of diodes in the L-Box increased from 23 to 47 (if not, proceed to step 4):
   In the registry, browse to HKEY_LOCAL_MACHINE \SOFTWARE\Scitex \Projects\LOTEMFLEXO and modify the following parameters:
• Default Last Laser Number—change from 23 to 47
  (select EXPOSE).
• Last Expose Laser Active—change from 23 to 47
  (select IO OBJECTS\LASER GROUP\Laser Group).
• Last Laser Active—change from 23 to 47
  (select IO OBJECTS\LASER GROUP\Laser Group).
4. Update the laser factors:
1. In the Hardware Tree, browse to Boards and right-click DDB Card.
   
2. In the DDB dialog box, in the Lasers Factor section, click Reset All to 0.
   
3. Change the Factor for each diode according to the data sheet in the upgrade kit.
