My apologies, I accidentally posted this to the wrong board. I'm trying to figure out how to shift it to the "Other Printers board"....
I have an HP Color Laserjet 5550 DTN displaying the following error on it's LCD screen "RFU LOAD ERROR RESEND RFU OVER PARALLEL PORT". I connected via a mini-parallel cable and issued the command via Windows command prompt:
copy /b clj5550fw_07.200.5.rfu lpt1:
The LCD screen read "RFU RECEIVED, CYCLIING POWER". After at least 20mins the printer had not power cycled so I turned it off and back on again. I can now see nothing on the LCD screen. No memory checking viewable and no LEDS light at all.
Is there a way to perform the firmware upgrade again or am I going to have to purchase a new firmware DIMM. I believe the part number for a new firmware DIMM is HP Q7725-68002?
