You may find it necessary to remove the loading and unloading
unit to replace the encoder. 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.
Prepare a work space upon which you can place the assembly.
Unfasten the screws (#169,14,15) securing the metal strip
(#83) to the spring plate. Remove the funnel.
Release the tension on the film guide (#58,57,61). Loosen the
screw (#85,164) and the spring (#86).
Release the set screw (#161).
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. Remove the screw (#85), tilt the guide and move it sideways.
Pull out the cube.
Remove the defective encoder.
9a. For encoder counters (#2). Disconnect the encoder connector cable.
Unfasten the hex screw that fastens the counter to the holder (left side: #55, right side:
#65).
1a. For encoder counters (#2). Fasten the hex screw that fastens
the counter to the holder (left side: #55, right side: #65). If the encoder disk is not in
the center of the detector, release the screw (#22,23,24) and move the plate until the
encoder disk is in the center of the detector. Connect the encoder connector cable.
Re-assemble the guide on the spring plate (#82).
Put back the second guide: tilt and insert the guide onto the
assembly. Check tension and re-install the funnel.
Re-assemble the Unloading Guide. Put back the loading system.
Power on the imagesetter using the control panel ON/OFF
switch.
