I have recently bought colour tape for the 33.
The printer has a black substance that pushes the printhead towards the
paper. This has dissolved into an oily-like thing, and there is zero
pressure for the head against the paper. I will try to put a licorice
candy (L?kerol) in its place as a kludge, but it very likely won't last.
Do you know what causes it? Where to get a new one? Is that SUPPOSED to
happen?'
Confused Regards

Mine did exactly the same thing and I haven't fixed it yet, so I am
looking forward to hearing from the experts.
My amateur opinion is that it's probably supposed to be a fairly hard
piece of rubber from the pounding it takes. I was going to find some
reinforced tubing or vulcanized rubber (like what tires are made of) if
that gives you some idea of the consistency I was shooting for.
Good luck!

Firm but resilient. Too hard and it will damage the type element.

I have never tried a substitute, but those sound promising.

While it's not what you want, it's common that the rubber hammer pad
turns to a candy-like goo. I don't think you want to fabricate a
substitute out of something with sugar in it... it will get all over
everything and make it sticky.
I bought a couple replacement pads from Western Numerical Control a few
years ago (http://www.westnc.com/). I can't find TTY repair parts on
their site now, but perhaps if you contact them, they will be able to help.

Fixing some hardware with a piece of candy has got to be the coolest thing
I have ever heard of ;)

I had the same problem. For a temporary solution, see if you can find
something like this:

to the bottom of equipment to prevent scratching a desk.

I have two Teletypes that had the same problem. What I did was remove
all the gunk from the print head and the hammer with Goof-off and an old
toothbrush, and then I took a regular new pencil and cut off the eraser
with an Exacto knife. Then I took a drop of super glue, and stuck it in
place on the hammer. After trimming a little, ta-da! Mine has been
working just fine now for close to two years. I'm sure that this is not
as nice as having the correct part, but who has the correct part?
Probably a better solution would be to find some soft flexible rubber,
but I didn't have any at the time, and the eraser works great so stopped
looking!

Actually, I do have some of the original parts, in a box of Model 33
spares (which also contains things like answerback drums, gears, a motor,
etc). Alas, as you might have guessed, the spares are decaying too :-(.
Fortunately the metal parts, etc that I have are still good.

THis is a common problem. It should be a piece of fairly hard rubber.

No, please don't, not unless you like cleaning the type cylinder and the
rest of the carriage mecahnism.

Well, I can't believe it was _designed_ to decay like that, but they all
do. My first gusss as to a suitable replacement would be a self-adhesive
cabinet foot, available from electronics component shops. It's about the
right hardness, and it will stick in place, at least well enough for testing.
