I have a couple of prints in which part of the perfs are visible on the left side of the screen when projecting.
Are there any gate adjustments which will eliminate or reduce this?

It's more likely the prints are at fault and not lined up correctly when printed. Look at the troublesome prints against the good ones and try to see what I mean.
I believe that a lot of Elmo projectors show more on the screen than many other makes.

Maurice,

when you say

do you mean examine the prints physically?

Posted by Maurice Leakey (Member # 916) on October 29, 2013, 04:14 PM:

Yes. Hold small sections of each up to a light together and examine with a magnifier to see if the positions of the perforations of each are different in relation to the position of the printed picture frame.

Mike,

If that is really distracting, cover a bit on the side (where the perfs are seen) of your lens with piece of paper.

Posted by Michael O'Regan (Member # 938) on October 30, 2013, 01:31 PM:

It's not too distracting. I just wondered if I needed to adjust something is all.

Mike,

I think theoretically you can adjust it, but then the correct prints will have some trouble when you screen use the same projector.

I think this is a similar case with the sound head when the azimuth was not on correct position during recording. On your tape you will hear mumble (muddy) voice. You can correct it using the azimuth adjustment on your tape recorder' sound head, but the correct recording then will be heard muddy.

I suggest you contact a Eumig expert in this matter, perhaps the friend who accompanied you last Saturday.
He was helpful when I had a similar problem with my GS-1200.

Maurice,

Its an Elmo ST1200 and, yes, I shall certainly contact Kev about it.
Thanks.

Your problem with your ST-1200 and mine with my GS-1200 was an expansion of what said above "I believe that a lot of Elmo projectors show more on the screen than many other makes".

I bought a print of Walton's "Crazy Motoring" and had problems on screen with my GS-1200, on advice, I checked the print visually and it showed it was different from other "good" prints (it ran perfectly on other makes of projector.) This is when I was told about the Elmo gate masks being larger than many other makes of projector.

Perhaps other members have also found this with Elmos.

Yes I agree the gate aperture is larger than the average projectors. Also, the whole film transport assembly is less forgiving of films printed not exactly up to spec. In this case, though, I suspect a problem of print slitting: probably, upon close examination, you will find the area between the sprockets and the film edge is a bit wider than usual. At the end of the day, this is a print problem rather than a projector's problem, and in your shoes, I'd feel happy you can screen these prints without major issues, such as loop loss. It's not uncommon that a print out of standard, which can be correctly or at least acceptably screened with other makes, on ELmo projectors may be quite unsteady due to loop issues determined by unprecise ("borderline") slitting. Live with them, screen them, be happy!

Yep. I'm happy to do so. I just wondered if anything needed to be adjusted. If not, then I'll soldier on.
