Hi Everyone,

I just got a Model 14 Typing Reperforator and have a few questions.  Seems 
to run ok so far on my fox box.

1) The perforations in the tape don't go all they way through and don't 
create a pile of chad.  I believe I have heard of "chadless" reperforators 
and perhaps that's what this is.   Is that correct that the reperforator 
should leave the chad "hinged" onto the tape or should it punch all the way 
through with the chad ending up in some collection box?

2) Printing is almost non-existant.  I replaced the ribbon with a known good 
ribbon but there is hardly any printing on the tape.  Ribbon advances 
normally and reverses when gets to the end.  If I had to guess, I think the 
ribbon has so much tension on it that when the typebars hit it, they don't 
have enough force to smack the ribbon against the paper.  It did print for a 
few letters prior to my changing the ribbon but only the faintest of images 
now.  My thinking is that I have the ribbon strung incorrectly or there is 
some mechanism for adjusting the tension.

Here are a couple of photos:

Here's the stringing of the ribbon:

It looks like you have a chadless reperf.  The chad stays with the paper 
tape and is only punched out about 70 % of the way.

The ribbon looks to be installed correct under the spring thing.  Look under 
the tape and see if there is something like hard plastic for the paper to 
stop against when the key hits it.
