The aforementioned MFD is presenting non existent jams whereupon I did check the registration flag which had its spring out of position.After its restoration,the jam still hadn't cleared.I then exchanged the MP tray/registration sensors to see if there would be any effect but to no avail.Tried accessing the service program mode...no response.Opened the back cover & checked the wires..so far,so good.However on the IO board,LED301 is continuously blinking:same to BICU board,LED1 next to c145. My query is should these LEDs be blinking or is this indicative of an anomaly.Could the board(s) be malfunctioning such as to cause the permanent paper jam sign?is there something I'm overlooking?if I were to disconnect all switches,should the MFD boot normally?Looking forward to your favorable response...Regards.
