Can't find much in the service manual. The envelopes aren't opening and getting a error message E082 "envelope not flapped". Cleaned all the rollers and was able to one or two envelopes to go through but then jam and same message again. Envelopes crunch up a little and jam right where they turn over to open flap.

I normally wouldn't work on equip I don't know but this is for a good customer who claims they can't get anyone to work on it, including Pitney! About 6 months ago I replaced the accumulator belts & paper tray feed rollers and wasn't too bad so now they think I'm an expert on it. Ha-ha

Thanks for any help
