On our install this summer of several Ricoh printers of the "4" generation, we had great difficulty getting the card readers to work. We are currently operating but the solution we came up with is very kludgy and is the product of a sequence of lucky observations. Has anybody else had similar difficulties? If you have an actual elegant solution (or just a better understanding of the situation), we would be very interested to see it. If you would like to see our kludge, I can publish it here.
The Ricoh models that we installed this summer are: MP 2554, MP C4504, and MP 4054
