[GreenKeys] 35-KSR misprinting

[Jack]

The type hammer timing might be off. This is adjusted on the
front plate and on the type hammer carriage. 
It times when the hammer hits the pallet. If it's off,
it hits too soon and/or hits two pallets. If you manually cycle the
machine, with the code for a printable character set up in the
code bars, check if the hammer squarely hits the pallet.

The type hammer might be damaged (make sure it has a flat surface
where it hits the typebox pallets). Sometimes the hammer's metal face cracks
resulting in a jagged surface that slips off the pallet. 

You might have the dreaded "Model 35 7th Pulse Cam" problem. This
makes the front plate/typebox positioning every "sloppy". The 7th
pulse cam on the mainshaft actually develops a "dent" due to the
fact that the roller that rides on the cam is actually airborne before
it crashes down on the cam. Eventually, the dent develops. I used to be
able to diagnose this problem from across the room even before
looking at the machine. The 35 has a very "sick" sound as it's
running. The best way to fix it is to replace the entire mainshaft
with a new one (the old Ma Bell method). It's like giving a 35 a heart
transplant. 
New 35 mainshafts, however, are hard to find.

Of course, there could be other contributing factors....

Dear Greenkeyers

I wonder if anyone can diagnose from the attached picture of misprinting
just what is going wrong with my 35-KSR. The problem occurs with whatever
character follows a double quotation mark: "

It's the next letter after the quotation mark that gets misprinted. The
fault does not occur if I'm doing the typing (say, entering a line of BASIC
code to the computer) but does appear if the computer is typing (say, if I
LIST my BASIC program).

The fault appears to arise from the hammer hitting the wrong types in the
typebox. Just which wrong type is hit each time can vary and, as the picture
shows, sometimes the hammer appears to hit two types.

Anyone seen this kind of fault before and know how to fix it?

Regards

Gabriel Egan
