5.2 Adjusting the exposure unit
This adjustment must be made if the exposure unit has been moved. First the lens has to
be adjusted. By moving the lens backward or forward the size of the picture can be changed.
This adjustment only has to be made if the lens has been moved in it's holder. Next is to
adjust the mirror and the position of the exposure unit sidewise.
As a help a frame drawn on a paper is needed. This frame should be inserted in an empty
cassette and the camera will then be made to present a corresponding frame on the expo-
sure display which will be projected on the paper in the cassette using a special test mode
of the camera. The size of the projected frame should then be adjusted to match the frame
on the paper.
The size of the frame should be 13mm high and 64mm. You may very well make a copy of
the illustration below. Just remember to check that the size after copying is still 13 by 64 mm.

• Insert the paper with the frame into the cassette as illustrated above.
• Take the camera somewhere where there is not to much light.
• Open the camera and remove the baffle that covers the exposure unit by loosening (not
removing) the two screws in the front of the baffle. If the exposure unit needs to be
adjusted sidewise the two screws that holds the exposure unit to the base plate should
be un-tightened.

you from the moving carriage when the camera is operated!

• Insert the cassette. Press the Sift+F1/Adjust. The camera will open the cassette and
keep it open and display the test picture.
• Now make the frame displayed on the exposure display show on the paper in the cas-
sette by tilting the mirror and maybe moving the lens.
• Next adjust the lens so that the size of the frame projected on the paper fits within the
frame on the paper. The lines of the projected frame is probably wider then the line on
the paper. They should be on or within but not outside the lines on the paper. Adjust the
position sidewise by moving the entire exposure unit if necessary. If the picture is trape-
zoid (sides are not parallel) can be corrected by moving the mirror backwards or for-
wards in the holes it is mounted in. Just loosen the screws and slide it. If the upper and
