5.1 Sensor adjustment
Left
The left and right sensors senses the front of the cassette. When the cassette is inserted
well enough the opening cycle may start. The middle sensor is a pin that should enter a hole
in the front side of the cassette. If the cassette is not well pushed towards the left side of the
opening of the cassette the pin will hit beside the hole and the middle sensor will be pushed
by the cassette and by detecting this the camera knows that the cassette is not properly in-
serted.
To adjust the sensors, enter the set-up mode of the camera. Select Sensor adjustment. Here
a picture is shown showing the status of the three sensors. Note that this picture is also
shown on the exposure display so if the baffle over the exposure unit is removed there is no
need to look at the operator display to do the adjustment.
When no cassette is inserted all sensors should show OFF. When a cassette is inserted in
marking position the left and right sensor should show ON and the middle sensor should
show OFF.
Adjusting a sensor is made by loosening the two screws that holds the corresponding opti-
cal switch board and then slide the board until it switches between ON and OFF in the ap-
propriate position.
The left sensor should switch to ON when there is about 1.5 mm until the cassette is fully
inserted.
The right sensor should switch to ON when there is about 1.5 mm until the cassette is fully
inserted ,but this adjustment is not as critical as the left sensor. What is critical is that when
both the left and right sensor are both switching to on the hole of the lid in the cassette must
be in a position where the pin of the opening carriage will enter the hole. This means that
the setting of the left sensor is quite critical. 1 mm here will mean 1 mm in the position of the
hole. The right sensor is not so critical,1 mm in her will mean about 1/10 of a mm in the po-
sition of the hole.
The middle sensor should be adjusted to switch to ON in the middle of its movement. Take
a cassette and insert it but keep it a few centimeters from the left side of the cassette bed
so the pin of the middle sensor does not hit the hole in the cassette. Move the cassette in
and out to see how much the sensor moves. Find the middle of this movement, hold the cas-
sette there and adjust the optical switch board so it switches at this position.
When the two screws holding an optical switch board has been tightened the sensor should
be checked once more as the board may move when the screws are tightened.
