Hello,

I have a Sankyo Dualux 2000H Projector which hasn't been used for a long time. It looks like the bulb had been replaced but was not the correct bulb so I got one from eBay and it fits in and works but the light being projected out is a horizontal slit instead of a rectangle. Is there some adjustment that needs to be made or some part that I'm missing? Any help would be appreciated.

Regards,
Len

Is the slide control which alters the ratio between Regular 8 and Super 8 in either of its fully home positions?

Yes, I have tried with the slide control in the regular 8 position (fully at the bottom) and super 8 position (fully at the top) and the problem is occurring in either case.

I don't know if this is useful information but when I go from forward with bulb on, it is showing a slit but right when I turn bulb off (move control to forward without lamp), for a second before the bulb goes off the projected light seems to be full and rectangular.

Probably, Martin. Here's an extract from the Instruction Book:-

"NOTE: The Auxiliary Shutter retracts automatically from the optical path when the Loopsetter Guide is firstly depressed and the Lamp is turned on.

To make height adjustment or to determine the size of the projected image by projecting the light shape on the screen, the above procedure can be followed. Make sure the Loopsetter Guide is pushed all the way down.

If the Loopsetter Guide is depressed after the lamp is turned on, the Auxiliary Shutter will not retract. In this case, turn the Rotary Switch back to "FWD" and then perform the above operation."

Hope this helps you, Len.

Thanks Martin & Maurice for your help. When I held down the Loopsetter guide then turned the lamp on I was able to see the full light projection. I was able to play regular 8mm films (yay!). But I had some issues so I have some follow up questions:

1) when I was playing regular 8mm film I could only see about 3/4 of the height of the film image. Is there some adjustment I can make to see the full height of the image? I did try different positions on the framer lever.

2) I had no success playing super 8mm films. Firstly I'm going to ask another complete noob question and that is on this unit for super 8mm do we put the holes on the same side as when playing regular 8mm? I had the setting on super 8mm and when I attempted to play, I had to hold down the Loopsetter guide for the auxilary shutter to retract even with the film fed. Another thing that was happening was that if I closed the metal flap against the film, the film would stop feeding (which was not happening when I was playing regular 8mm). While holding down the loopsetter guide I tried to play the film but couldn't get the image to be intelligible (as mentioned I had the metal flap open when I was playing because otherwise film feeding would stop).

Thanks,
Len

I'm not a technical person but it sounds if there is something wrong somewhere. Both types of films have the perforations towards you. The claw takes both films. There are no sprockets, travel is by rubber rollers.

Make sure the rewind lever (R) is always pushed in unless you are actually rewinding.

Not sure what you mean by referring to a metal flap.

Is this a new purchase? You say it has not been used for a long time, by you, or a previous owner?

"Metal flap" = Pressure Plate.

Thanks Maurice again for your help. The rewind button was pushed in but I pulled it out to rewind position and pushed it back in several times. After that I tried the super 8mm film and was able to play it fine (double yay) without holding down the loopsetter guide lever and with the pressue plate closed. Maybe it was playing a few regular 8mm films that got some of the dust and grime off that had accumulated over the years.

>Is this a new purchase? You say it has not been used for a long time, by you, or a previous owner?

It is actually my elderly father's. He wanted to watch and transfer to dvd some of his old regular 8mm and super 8mm family film that he shot back starting in the 60's but he had not used the projector for maybe 30 years because he had not been able to get the projector to work. It's quite amazing to see 50 year old films on my grandmother who I don't have any memory of and of my parents in their prime!

Thanks again,
Len

That's great news, Len, I am pleased to be of help. It's quite something to watch personal movies after a long time.

I'm not sure if my children appreciate seeing themselves filmed over forty years ago!

Len, I'm a little late on this, but I would suggest checking the drive belt on the projector if it is the original. Typically they turn to goo after as many years as this projector is old. It will cause a black gooey mess inside the projector.
