We got a WorkCentre 6655, not a 6655i (this was a free replacement as our Phaser 8560 died so we didn't have a choice of model.) The printer works fine except will not print from the AS400 (iSeries). We keep getting the message "operator action required on device devname (c r)" on the AS400. While searching for a solution, I came across http://www-01.ibm.com/support/docview.wss?uid=nas8N1019526 titled "Information on Printers from Xerox and Fuji Xerox". Within it, it is stated "This document contains information on the capabilities that are supported on printer hardware from Xerox." and "Most PCL printers use port 9100 and regardless of the hardware, a PCL Manufacturer Type and Model, such as *HP4, *HP5SI, *HP4000, etc. will work." I stopped the printer, varied it off, changed the type and model to *HP4, varied it on, started it and we still get the error. I rebooted the printer after this change, too, and that did not help either. Has anyone else run into this and have any suggestions?
