Film Loading and Unloading System

filmload.gif (7138 bytes)

The Dolev 800 imagesetter accepts film, paper or polyester plates. The media is loaded onto a loading cassette and inserted into the imagesetter. You can select one of three loading cassettes: a small (12 in), medium (20 in) or large (33 in) cassette.

The Dolev 800 has an automatic film loading mechanism. Once the film loading cassette is inserted, press the SET UP key on the control panel and film loading begins.

The film is pulled between a set of rollers and onto the exposure drum. The film is cut, and a vacuum system ensures that the film is held down on the inner drum surface. During set up, the imagesetter cuts and ejects the first piece of film. The reason for this is that a small piece of film was exposed to light when the cassette was carried from the darkroom.

The next step is to expose the film. You choose your file, file size resolution, and layout. The film is exposed and ejected. The ejected film is sent to the output cassette, or to an optional inline processor.

Description

The three Dolev 800 loading cassettes are used with medium to high contrast red sensitive lith or line film, paper, or polyester plates.

Three steps are required to load new exposure media:

Bringing the Cassette to the Darkroom

  1. Open the loading cassette compartment door. To remove the small (12 in) or medium (20 in) size cassette, push back the locking bar.

  2. Remove your cassette. Carry the loading cassette to the darkroom.

  3. The Large Cassette has a separate compartment outer door. It is located on the front on the imagesetter. Open the door. Inside you see another compartment door. The compartment houses the large (33 in) cassette. Open the door.

  4. Remove the cassette. Carry the loading cassette to the darkroom.

Mounting Film on the Loading Cassette

  1. Check that the film* you plan to load on the cassette is in the darkroom before you lock the door and turn off the lights.    
    (* Throughout the guide, the term "film" refers to all exposure media.
    Caution: All Dolev imagesetters require a bright cyan light source for film development. Do not use red or yellow illumination!)

  2. Close and lock the door to the developing room.

  3. Light the bright cyan light.

  4. Open the loading cassette. Two latches secure the cassette lid. To open the loading cassette, push the latches horizontally toward the center of the cassette. Pull up on the lid until it is in a resting position.

  5. Grasp the outer surface of both mounting rims and lift the film spool out of the cassette.
  6. Look at the mounting rim. It consists of two sections: an inner ring that secures the rim to the spool, and an outer ring. Twist the inner ring. Remove the rim from the spool.
  7. If the cassette contains a film roll, remove it from the spool. Place any unexposed film in a film case or container. Mark the container.
  8. Place the new roll of film on the table. Note the film position: rolled away from the cassette, emulsion down.
  9. Grasp the spool by the fixed rim. Insert the spool through the film roll.
  10. Put the mounting rim in place on the spool. The inside surface of the rim should be flush with the roll.
  11. Tighten the removable rim by twisting the inner ring with the tightening tool.
  12. You are ready to put the film in the cassette. Lower the spool into the cassette. The ends of the spool fit between the prongs of the cradle.
  13. Place a short piece of film over the edge of the cassette and shut the cassette lid. Allow 30 mm (approx. 1 in) of film to stick out of the cassette. Check that the film is straight (parallel to the cassette lid).
  14. Take a pair of scissors and cut the two corners of the film at a 45o angle. This prevents film from jamming during loading.
  15. You are ready to leave the darkroom and load the imagesetter. Before you leave the darkroom, double-check that you have protected any unexposed film.

Loading the Loading Cassette on the Imagesetter

  1. Open the loading cassette compartment door. If you are loading the small or medium size cassette, push back the locking bar. Make sure the medium size loading cassette is loaded on the left side and the small cassette is loaded on the right side. The film must be extending from the bottom of the cassette on the side closest to the imagesetter body.

  2. Fold down the cassette handles.

  3. Pull the locking bar forward. Close the film compartment door.

  4. The large cassette has a separate outer compartment door. Open the outer door. Open the interior compartment door. To mount the large cassette (33 in) on the imagesetter, place it on the interior door and slide the cassette into place. Fold down the cassette handles and close the cassette chamber door.

  5. Close the film compartment door.

  6. Use the "set loading" command to load and unload the first film.

Film Output & Development

Film Output
Developing Film without an Online Processor

Film Output

Two Ways to Output Film: There are two ways to output film. Your imagesetter outputs film to an output cassette, or through an internal conveyor directly to a processor.
The Output Cassette: The output cassette is track mounted on a door of the imagesetter. When installed, exposed film is ejected into the cassette.

Press the lever on the imagesetter output cassette door. Open the door. Grasp the cassette handle and pull the cassette toward you.

Developing Film without an Online Processor

Caution: Do not open the output cassette until you are in the dark area and the door is LOCKED!

  1. Carry the unloading cassette to the darkroom. The room is equipped with a bright cyan light.

  2. Close the developing room door and lock it. Turn on the cyan light.

  3. Open the unloading cassette. Flick the two fasteners on the front of the cassette to open.

  4. Remove the films one at a time. Feed each piece of film into the processor. You may find one narrow (less than 4 in/10 cm wide) strip of film in the cassette. This is the piece of film that was exposed to light when a new loading cassette was loaded onto the imagesetter. Dispose of this waste film.

  5. Depending on your processor, you receive a signal from the processor when you are allowed to feed each subsequent film. When you have fed the last film into the processor and received the signal that the feed is complete, you may unlock the door.

  6. Note: Be sure to check the bottom and sides of the cassette carefully for any film that may have slid into the base of the cassette.

  7. Replace the output cassette on the imagesetter. Close the imagesetter door.
