We have started counting absentee ballots in Marin.  We 
  are getting a significant number of the following error messages.  
  
   
  NO ENDER MARK - the ballot will usually be taken on the next 
  try
   
  NO BACK LEFT TIMING MARK (0 or 52) - these also run on next 
  try or so.
   
  I've looked at the ballots and find no discernable reason 
  for them to be stopping or giving this message, as they have all appropriate 
  timing marks.
   
  I don't expect there's anything to be done, but it could be 
  looked at prior to next election.
