I have no idea what I am doing, but I am very mechanically minded and have figured out most of the problems so far. I have a number of repair manuals for this unit, BUT I am at a loss here. I have cleaned and oiled this unit and corrected a number of issues. Currently, my upper/lower case are not aligned horizontally. The lower case is printing solid, the upper case is printing about 1mm high and the top of the letter appears to be missing the ribbon. Printing red gets a total character. There is still enough play in the ribbon guide to go higher and there seems to be enough play in the carriage to go up a mm but it seems to be hitting something other than the carriage stop pins in front, I think designated as CI on plate 3.
I assume the adjustment is in escapement, but I can't figure that one out.
Any ideas would be appreciated.
