THE SHUTTER IS NOT OPENING...

Machines this applies to: Itek 430 & 435

The most likely cause of this is a broken shutter spring.  Here's how to fix it.

1. On newer 430 cameras with LCD displays remove the small cover mounted just inside the lens recess and disconnect both of the connectors inside.
2. On all models, remove the lens unit from the camera by unscrewing the three small knobs located around the lens recess. Support the lens unit while doing this so it doesn't fall and damage something when you get it loose.
3. On older 430 and 435 cameras disconnect the coil cord from the back of the lens unit.
4. Take the lens unit to a convenient work surface.
5. On older models the shutter is mounted on the back of the lens: remove the 4 screws holding the shutter assembly to the back of the lens unit.  On newer models the shutter is on the front of the lens inside the lens recess: remove the 4 nuts holding the shutter assembly.
6. On all models, turn the shutter assembly over so you can see inside.  You'll probably find that a small spring which connects two moving parts has broken.  Form a new end and reconnect the spring.
7. Remount the shutter assembly to the lens unit.  On the front mounted shutters this can be a little tricky because you must be sure that you don't pinch any wires between the two assemblies when you put the shutter unit in.  It's easier to manage the wires if you manually open the shutter blades and hold the wires by putting your fingers through the shutter opening.
8. Reassemble the lens unit to the camera and reconnect the cables.
