Dks 1750 Centering Process Step By Step

In my old DKS 1510 I made centering process several times with no problem .

Now I have DKS 1750, I want to make centering process but, as I see, is more

complicated and I don't want to do anything wrong.

In DKS 1750 centering process is more complicated because has multiple exposure

and I have external feeder, and if is not well done single prints are ok, but multiple

(4 by 4) prints not (the right row is ok but the left row is not equal centered), and

when you print with the external feeder is not equal too.

I have:

DKS 1750 with external feeder.

In the internal one I always print with a double track magazine (6 inches wide paper)

The external feeder is used with 7 inches and 12 inches paper.

Any advise, trick of doing it with the sizes of paper I have, step by step?

Well, I tried myself to do it and had success.

I couldn't print external feeder patterns because I had to use double track magazine.

But this is not very exact because when you print 4 by 4 is very hard to get exact centered images as I see.

This is the copy off the text I wrote in another topic, but here I wanted to wrote it some time ago

1. Clean both upper and lower rollers inside feeder

2. Clean all the sensors on the expo deck

3. Make sure that both LCD and Lens turret belts are properly tight, and to be sure about that, loosen all 3 screws which hold the mottor and let the tightening spring tight the belt and then tight the mottor screws again

4. Check LCD and lens zero position and adjust its sensor position if necessary to get it in orange range at least

5. Chek LCD and Lens offset exposure on expo deck and adjust if necessary

6. Check feeder extraction lenght and adjust

As I am on vacation, I do not have manuals in front off me to write down proper names off the adjustaments which follows the ones I already stated in the text above, but I think that very few off my colegues done this belt adjustment or knew about it, but on one location I realise that this spring is there just for that purpouse and before I done that I tried numerous times to measure the exposed centering patterns, but the values were not stable from one measurament to another one, but after I adjusted the lens belt tension I got perfect WB after finishing all the other adjustments necessary to be done afterwards

Do all the necessary centering test like lens centering...
