It never ceases to amaze me; just when I thought I knew all the Silent 700
models, someone comes up with a variation I haven't seen.

My latest Silent700 is a Model 735 KSR. The carrier for the print head
was broken, but repairable, as was the mechanism for adjusting the print
head pressure against the paper. After making those repairs, I had print
quality similar to what was shown in the last picture. However, some
judicious adjustments cured that, and it now prints fine.

Additionally, the TI Silent 700 Service Manual I have does describe a
procedure for cleaning the print heads. IIRC, you take a sheet of
plain, regular paper, soaked lightly in alcohol, and run it through
the platen, then type on it. The alcohol may be a figment of my fatigued
imagination; but the procedure isn't.
