Quoth dvcorbin at optonline.net, in part:
[...] the type cyclinder spinds and lifts, the hammer
strikes...and a
really faint improperly alligned imnage is all that gets printed [Yes I
have a brand new ribbon on it].
So at this point, I am wondering how to address this problem...The
cylinder is well cleaned (boy was there buildup), the characters look
sharp on it, the rubber bumper on the hammer is in apparant good
condition [and not "soft"]....
But the character it tries to print is the correct one? If so, the
situation doesn't sound too bad. :) I spent part of today tinkering
with the ASR I just got and was working on exactly the same issue, oddly
enough; so maybe I can point you to the information I was using. Have you
got a copy of the January '63 ASR-33 technical manual from Bitsavers or
one of its mirrors (273B_Mod32_33_TechMan_Jan63.pdf, in the Teletype
section)? If so, on Adjustments p. 4-94 there's a quick guide to some of
the print-quality adjustments. (The faintness of the image might be the
horizontal alignment of the platen, which is covered on p. 4-64.)
...I have to say, I'd forgotten the beauty of ASR-33s! The level of
mechanical acumen, intricacy and craft of the design never ceases to
impress me. _Damn,_ these people were clever! I'd forgotten just how
enjoyable it is to see that ingenuity with my own eyes... and it's good,
because that enjoyment somewhat offsets the creeping terror I sometimes
get that it might never go back together again and I've stupidly opened
Pandora's Box Of Spare Parts. :) :) :)
