Disassembling the Lever Detectors

1. Open the loading system compartment doors.
   
   
2. Remove the light-proof covers from both sides of the unit.
   
   Note: If the problem is with the right detector, you do not need to disconnect the electronic harness cable connectors on the right side of the Imagesetter. Removing the light-proof covers is enough.
   
   
3. Remove the E-ring that secures the top of the left lift-o-mat piston. Tilt the piston downwards.
   
   
4. Open the two track locks on each side of the system.
   
   
5. Grasp the handles from both sides and gently pull the system forward 10 cm.
   
   
6. Disconnect the connector from the detector.
   
   
7. Remove the two screws that hold the detector.

Assembling the New Lever Detector    

1. Put the new detector in place. Tighten the two screws that hold the detector. Maintain a gap of 2 mm while the lever is in the closed position.
   
   
2. Reconnect the connector to the detector.
   
   
3. Assemble the connector holder back into place.
   
   
4. Slide the loading system in place. Close the track locks.
   
   
5. Return the loading system back to its place and close the lockers.
   
   
6. Put the film cassettes back in their compartment.

Adjustment

1. Enter the Dolev 800 Diagnostics under UTILITY / DETECTORS
   
   
2. Press the number / letter next to the relevant lever (either upper or lower lever)    
   
3. Make sure that the relevant lever is in the CLOSED position.
   
   
4. Release the two screws that hold the magnets to the base and move them forwards and backwards until you receive a steady ON message.
   
   
5. Tighten the two screws in the correct position.
   
   
6. Open and Close the lever several times and make sure that the reading is good.

Check and Test
