In the following steps do not use clear film nor
plastic leader to focus the sensor on. Clear
film will make focusing difficult and plastic
leader is typically much thicker than film,
which will affect the fine focus of the sensor,
plus the white surface will actually make the
focused dot harder to see, compared to regular
film. Thread your film onto
the gate and move the film past the leader to an
area that is fairly dark, as shown in the photo
above. Loosen the THUMB
SCREWS and use the HANDLE
at the back to PUSH and PULL the sensor bar in
and out. Do not attempt to turn the HANDLE. Just use it to
slide the bar in and out until the beam is centered
on the film. Hold
back-tension on the film to keep it flat and gently
slide the LightPin Sensor up and down until the red
dot has a fine focus. (This is much like focusing
the sun using a magnifying glass as a kid.) Once you
have the red dot focused, gently tighten the front THUMB SCREW on the end of
the sensor bar until snug. Do not over-tighten or
you might damage the LightPin Sensor housing tube.
Once you focus the red dot, you should never have to
focus it again, even if you remove the gate and then
put the gate back in place. However, it is easy to
loosen the front THUMB SCREW
and recheck your focus of the red dot at any time to
ensure optimum performance.
NOTE: Ambient room light will not affect the
LightPin Sensor in any way.
Next, use the HANDLE at the back and
carefully slide the sensor bar in and out until the
red dot is centered on the sprocket hole path as
shown above then tighten the top THUMB
SCREW to hold the sensor
bar in place. Please note
that the placement of the dot for the Super 8 format
and the Regular 8 format are different. However,
once you set the placement of the red dot for a
particular format, you will not have to adjust it
again unless you change formats.
The front side springs have been
pre-tensioned in our shop. However, the tension
can be easily adjusted using an American 1/8th
inch hex wrench to loosen the set screw in the
collar, which can then be slid in and out to
loosen or tighten the springs. This can be
useful if you have old regular 8 film that was
incorrectly split and too wide or film that is
very thin and wants to cup easily due to any
side pressure. But, typically, no adjustment is
you can run the Universal like normal.
However, you will find that the format
selection switch up front as well as the
sensor knob no longer have any
functionality when using the LightPin
Sensor. Neither the selection switch nor
the sensor knob require adjustment when
using the LightPin Sensor gate.
