[GreenKeys] Model 28 - Top edges of letters barely visible

[N4BE_Jim via GreenKeys]

Thanks Jack.  Turns out the bottom tab on the type box was improperly inserted (jammed) into its clip by a previous owner, bending the clip.  The clip is what is tilted by the adjusting screw you mentioned.  Straightened the clip and it prints ok now.
