BilL/Kringle,
Not to beat a dead horse....but I too have a list of complaints but the one I will mention at this time is the speed. It's rated for the 7,500 per hour running envelopes the short way, yet our Neopost vendor has told us for years the machine is not supported to actually run that way. They refuse to stand behind any issues when running #10s the short way. However, for the most part we can but we have to use 'safe mode' 90% of the time when printing this way, yet when there's an issue, we are on our own.
Are both side guides movable or are they setup the same as the Mach 5? One of our issues with head life is that we can only use 1/2 of the head when running envelopes. The head on the far side of the Operator gets used 90% of the time because 1) when running the long way, that's the only place the envelope can feed and 2) when running the short way, the envelope has windows and does not get any print. Running envelopes backwards, the short way, jams. So we again cannot do much printing with the near half of the head.
