Description

The nine film guides are located behind the loading and unloading system. They are a part of the optomechanical assembly. The guides orient the film as it enters the drum, driven by the loading wheels (#72).

The two outer guides are different from the other seven. Each of the two has a film encoder (#60) and a magnetic lever (#56).

Assembling the Film Guides

Before You Start

  1. Two engineers are required when removing the Loading and Unloading Unit. Do not attempt to remove the system from the imagesetter unless at least two engineers are present.

  2. Prepare a work space upon which you can place the assembly.

Tools and Accessories

Set of Allen Keys

Disassembling the Film Guides

  1. Power off the imagesetter using the control panel ON/OFF switch.

  2. Open the left and right service doors.

  3. Remove the light-proof cover from the right side of the unit.

  4. Remove the loading system from the machine. Remove the funnel.   

  5. Remove the unloading guide from the Optomechanical Assy. Unfasten the screws (#169,14,15) securing the metal strip (#83) to the spring plate.

  6. Release the tension on the film guide (#58,57,61). Loosen the screw (#85,164) and the spring (#86).

  7. Release the set screw (#161).

  8. Begin on either side of the Feeder Loading Shaft. If you need to remove the end guides, perform the following: Skip the first film guide that has the lever. Unscrew the second guide. Tilt and remove the guide from the assembly.   

    Remove the end film guide. To begin, disconnect the encoder connector cable. Remove the screw (#85), tilt the guide and move it sideways. Pull out the cube.

Assembling the Film Guides

  1. Re-assemble the guide on the spring plate (#82).

  2. For the end guides:  Check the height of the magnetic lever. The edge of the lever cannot be above the surface of the guide. If this happens, film will jam on the lever during unloading from the drum. To prevent this, add a small fitting to the base of the lever. The lever cannot lift up as high.

    Remember to reconnect the encoder cable to the connector. Re-install the funnel.

  3. Re-install the unloading guide. Put back the loading system.

  4. Power on the imagesetter using the control panel ON/OFF switch.
