[GreenKeys] Troubleshooting papertape reader

[B Degnan via GreenKeys]

Hi all,
I have a question about reading a papertape.

Let's say I have two machines,  both in local mode.

I want to read in a papertape that has the following data on it:
S10400F3FF09
S11300000D7600F37E18F97E033C00004838002C7E
S113001000000000000000000000000000000000DC
S113002000000000000000000000000000000000CC
S113003000000000000000000000000000000000BC
S113004000000000000000000000000000000000AC
S1130050000000000000000000000000000000009C
S1130060000000000000000000000000000000008C
S9


Machine #1 - run the tape in the reader I get
S10400F3FF09
S11300000D7600F37E18F97E033C00004838002C7E
S113001000000000000000000000000000000000DC
S113002000000000000000000000000000000000CC
S113003000000000000000000000000000000000BC
S113004000000000000000000000000000000000AC
S1130050000000000000000000000000000000009C
S1130060000000000000000000000000000000008C

Machine #2 - run the same tape in the reader and a number of the lines do not line feed, typing over the line.  
This happens in the very beginning and every so often but enough to make it impossible to load a long program from the reader.

I have checked the reader and the form out mechanism.  Nothing obvious appears wrong to me, the unit is clean and oiled but not too much.

I welcome your suggestions.  What could be wrong?

Best
