Just a suggestion but I had a KSR33 which did much the same.
There was a piece of thin flat (spring?) steel on the carriage which
got broken.
On doing a carriage return, the ratchet mechanism which normally moves
the head to the right gets dis-engaged.
When the carriage gets back to the left, the piece of steel pushes
against an arm which re-engaged the ratchet, only on mine it wasn't.

I knocked over my previously working teletype.
After locating all of the pieces, I carefully re-installed as much I
could. The whole thing came apart, little pieces everywhere. The
typewriter became detached from the keyboard. Pretty bad.
I almost got it working, but there is one thing that I cannot seem
to fix.
The problem is that the print head is not moving horizontally along
the
line, it just says in place and types each character on top of itself.
I do know that the teletype is sending data correctly from the
keyboard
to the computer through the serial cable, and the computer is
receiving
the commands. Output from the computer to the teletype is received and
the print head itself is printing the correct characters. The
problem is
that the print head is not being moved to the right/horizontally. I
can
manually move the print head while in a operation (I can send a punch
command to the printout paper for example) and if I time it just
right I
can space out the printed characters manually so I can see what has
been
sent from the computer.
Can anyone help identify the fix?
I would be willing to travel to someone with experience who repairs
these (w/i 250 miles of Wilmington, Delaware), we can talk offline
about
service fees/trades. I have a lot of spare teletype and other parts.
Worst case I guess I will offer buy another stock ASR 33 if anyone has
one and this one can't be fixed. Is there such thing as teletype
repair
in the Philadelphia - Washington DC area?
Here are some pics, if they do any good. I can take more of targeted
locations.
