[GreenKeys] Kleinschmidt TT-4C/TG not printing

[Steve Garrison]

Where was the range finder pointing when you got it typing.  If not near the center when typing on a local loop, then there are other issues.

This evening I started spraying the Contact Cleaner more liberally all over the magnet area as well as on the electrical/electronic components behind the front panel.  This began to help.  I kept typing RY's (one-handed/two-fingered) while adjusting the Range and Armature controls back and forth.  I spent a lot of time doing this.  All I can say is that it finally started working properly. I was typing many lines of RY's as absolutely fast as I could without a single character dropped.

I tried slightly increasing it in stages up to about 45ma but the magnets seemed happiest at 30.  I may try a TU with an adjustable loop and see if I can get it lower and see if that helps . . . or hurts.

It is the only thing I can think to try at the moment.  Maybe the loop current is too high and/or the signal strength is just higher than these magnets can handle (??)
