Firmware update failed Hp Color LaserJet 5550 DTN

[mikevallabh]

Hi,

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?

Cheers,

Mike

Hello mikevallabh,

The HP Color LaserJet 5550 Printer series are commercial printers. I recommend posting in the forum for HP Business Support for a better chance at finding a solution.

Here is the link to the Commercial Laserjet board:
