4208 and 4101 are the jam codes I have received most recently. The job is 2 sided letter and has been reported not to have black edges. 1 sheet is found in the duplex and the other wrapped around the pressure roller. I have not seen it actually jam and the client reports what she sees.
We delivered the machines in July and has roughly 42K copies. It should be an up to date machine and I have not seen any bulletins regarding this problem. I have flashed the firmware to ver. 6. Within the test commands, I have found 161, which now has jam prevention mode, which I have turned on without changing any defaults within the jam prevention mode, the values are all set to -10.
Questions - Does anyone have suggestions or solutions? The jam prevention mode, is it for specific purposes? Example, for mountain regions or certain conditions. The values go from 0 to -30.
Thanks for any help.
