Hi fellow labrats,
richard from nanolab in Australia here. I have acquired a number of Model C printers in various states of repair. I have cobbled together a 35mm printer and most of two 16mm printers.
Right now I am at the stage of turning the 35mm printer on. I have sorted the 120 volt AC and connected that. I have connected the DC supply. I have a punch tape reader connected. I have connected all the connectors that I can make sense of.
With the power switch on, the lamp switch will turn on and off the lamp fan. I haven't inserted a bulb in the lamp house yet. The DC volt scale lights up as do a couple of other little lights on the main control pannel (footage rate, etc).
But nothing I do seems to make the motor actually run. Nor am I able to get any life out of the light vanes. While I don't have a punch writer (ie paper tape punch for the punch tape reader), i was hoping of using the three trim controlls to make basic light adjustments. There is an RF and notch detector for changes. I hope that it will be possible to load values into the trim controlls, and have those values activated by the notch detector.
It does make sense to me that the light vanes may not move or show signs of life until the motor is running.
The motor has a power cable as well as a multi pin cable connecting to the puch tape reader. But there are also two other cables (coming from the same part of the motor housing as the cable that connects to the punch tape reader). I don't seem to have anywhere for these two cables. Those cables are of the same vintage and type as the other multi pin cables on the printer - ie 1960s style aluminium casing with a screw collar, unlike the extra cables on the Schmitzer model C printer's motor (yes, have two Schmitzers too), which is a flat ribon type multi strand thing.
So, my question is, anyone have any thoughts as to what I need to do to get the motor to run? To be honest, I have only used a model c printer once. There are the three pesky buttons - Auto, Test and Stop. Does one normally just press 'Auto' to make the thing run? Are there microswitches somewhere that need to be closed in order for the thing to run? Will it not work without a bulb in the lamp house? I notice that when i connect the dc and turn on the lamp, the dc meter moves to the left, as though the dc power has the wrong polarity. This could, I guess, be because there is no bulb ... maybe.
So, I am keen to get this going. And I am keen for any suggestions!
