I am sure there are more differences between the 2 cards but lets forget about that for now. Why don't you put the 615 card in the 4200 and the 615 card in the 5100 and see if it makes a difference. The 4200 printer is a much later model then the 5100 so it is possible even the 615 will not give the info you want since it may not be resident in the 5100 to give to the card to transmit. If fact if memory serves me you can not print a supplies status report from the information menu on the 5100 while you can from the 4200 so as I said the information may not even be present in the 5100 to display.
