Polaroid 250 service manual




















When building an array using accumulated values, you should build it on the fly, otherwise the accumulated value go off from the official resistor values. The advantage of building the array with accumulated values is that all the resistors fit under the 12 point switch, whereas the individual values stretch out to one side making the array quite a bit bigger. Below that, it departs from a linear relationship. I've tested this on the original model and the model and the values are the same.

Wiring the model for manual shutter control Diassemble the shutter body. This will involve 3 screws and removing the aluminum sticker indicating the aperture setting. Unscrew the shutter circuit from the back of the body. You may need to cock the shutter to get at one screw.

Desolder the electric eye from the plastic ribbon cable. Note: even Polaroid did not allow their technicians to mess with the plastic ribbon cable, opting rather to replace the whole thing if it wasn't working.

Their repair manual wouldn't even allow their technicians to desolder the power cables coming from the battery compartment. The reason for this is because the ribbon cable melts when struck with a soldering iron. The key here will be to use as little heat as possible for removing the leads to the electric eye. Get some earphone cable from a non-working headset or earphone set and trim it to length.

I found this is the best cable to work with because it's thin and strong. Polaroid M Polaroid Countdown Polaroid Spectra. Polaroid 95A, 95B, Polaroid J Polaroid Cold Clip instructions. Polaroid One Step SE. Polaroid Pricing - - ' Polaroid Pronto.

Make certain your flash unit has the plastic cover still intact. This is important because flash bulbs especially old flash bulbs have a tendency to burst and you wouldn't want to send glass flying everywhere.

If the cover is broken, consider covering the bulb with a clear sheet of plexiglass. Do not use the flashbulb if there is not a solid cover. Attach the flash bulb unit to the camera by hooking it to the top of the camera and pressing the button in to extend the the gripping edge.

When pressed down atop the camera, release the button and the gripping edge will hold it in place. Fold down the protective cover and insert an M3 bulb into the socket.

Fold the protective cover back up. Set the lighting selector appropriately for flash photography based on your film speed this is the yellow selector boxes on the top of the front panel of the camera.

When you are done, press the red button on the flash to release the bulb from the socket. Check to make sure that the bulb hasn't broken, then open the protective cover, and then throw the bulb away if it is broken, obviously be more careful. Unplug the PC cord when you are done using the flash. If it is left plugged in, all subsequent pictures will come out over-exposed. Electronic flashes don't particularly work well or at all with Polaroid Land Cameras. The reason for this is that the camera has a 0.

This delay accounts for the time it takes for an m-series flash bulb to illuminate. This is called m-sync. However, electronic flashes do not have delay. This means that as soon as you press the photo button, the flash goes off, and then, 0. By the time the shutter has opened, the flash has already began to decay or left town entirely. This is particularly a problem if you are using the specialty PC adapter designed to work with the camera's flash unit.

The PC adapter for Land Cameras have a special plastic tab which push a cover inside of the camera out of the way to expose a special photo meter. This is used by the camera for metering the intensity of the flash, and adjusting the exposure of your picture. If you use this option and flash goes off right away, the shutter will remain open too long because it is waiting for the flash of light that has already occurred.

Obviously, this will over-expose the picture. This might work with some flashes, but is not a perfect solution, as the lighting from the flash may be unevenly distributed throughout the picture. You can then use the specialized PC adapter.

In my opinion, this is the best solution. If you are going to want to properly use an electronic flash with a Land Camera, you will not to hack the flash to be compatible with m-sync. A full guide to doing this can be found in this Instructable. You can build an electronic flash mount as specified in this Instructable. I have taken you as far as I can and you should by now be able to competently operate the camera.
