[GreenKeys] Having trouble printing a punched tape on my Model 15

Hi Derek,

What are you using to read the paper tape?  The FOX BOX puts a CR LF  
LTRS after each line.
Your transmitter distributor may be failing to read or transmit the  
LTRS code.  When this happens the carriage is not fully seated at the  
left when the next character is printed.

Hi Everyone,

This coming weekend is the Morse Telegraph Club's celebration of  
"Morse Day", the birthday of Samuel Morse.

Last year, I brought my model 15 to the Wabash depot in Ferguson, MO  
and printed a punched tape message on it explaining what we were doing  
with the operating telegraph in the depot.

Last year, I noticed that the tape I played back did not play back  
cleanly.  The punched tape message had the letters "piling up" on the  
left edge.  It did not do this consistently but did do it frequently.   
I assumed I had done something wrong.  I got out the hardware this  
evening and first ran the fox box with perfect printing.  I then  
punched a tape (complete with multiple typos) and then played it back  
several times on the Model 15.  It never really played back cleanly  
and I'm looking for some suggestions as to what I am doing wrong.   
Please note that the reperforator I'm using this year is different  
than the reperforator I used last year but I'm still getting the same  
piled up text:

Here is what I typed on the Model 15 to punch the tape on the Model 28  
reperforator that was on the circuit:

Here is the first playback...notice that the typos on line 3 "piled up".

Here is the second and third playback....getting worse:

Does anyone have any idea what could be the problem?

Thanks and 73,
