Ok so this is getting more interesting and follow-up to recent C454e posts about same issue. Customer called back and said the message is back "An internal error has occurred. System will reboot and error will be cleared"
Here is where it gets interesting, I went back today and it only throws message when trying to duplex and jams. NO ERROR or JAM CODES in history.
Customer said it had been jamming with duplex for several months only 1st duplex job of the day but would be good rest of that day after the one jam, with NO internal error message. Then when I did original call and replaced the FS-534 board for machine not recognizing the finisher & updating firmware they started to get message.
Printing and copying fine as long as not duplexing.
Disconnected finisher & put firmware back to G20-M1 (these were the 2 things I did before getting the "internal error" message) Figured it was worth a try but didn't help. Still get message with duplexing.
Thanks for the help
