Subject: [GreenKeys] Line feed on a 33ASR

Hi...
About line feed on a 33ASR..
I'm a retired Western Union Field Service Technician, and we used these
33ASR's with internal data sets (modems) as TWX machines. They also made a
good low speed pre Internet on-line terminal.
From what I remember, the line feed prowl was a
concentric adjustment on the
left side of the platen.
From the message I read, the selector part is the
problem. Typically first
check that the selection is working with a test of blanks
and rub outs, or a
string of *'s and U's. This will test for machine reversals. Then check
the line feed selection. Look for lack of oil, then weak or missing
springs, misarranged levers, etc..
Then oil. Dirt on the distributor and keyboard contacts and lack of oil
will kill the machine. The proper oil is in between 30 weight motor oil and
3 in 1 oil. Sears Roebuck used to sell what they termed "air conditioner
oil", which was almost an exact replacement for "Teletype oil", and also
in
a squeeze bottle. Be sure that someone didn't use grease instead of oil and
"gooey" the mechanism up!!
Your machine is a good teaching tool. Watch the selector mechanism work in
reversals and then the lined feed mechanism operate. whatever the problem,
it will become apparent..
Best,
