Instructions on how to do so are provided by HP here: The card CompactFlash Slot 1 (bottom slot) on board the logical work printer.It's a common printer, chances are you'll find another around the office. To fix a HP LaserJet 4250 bricks, two things are necessary: an of Type I CompactFlash card and other HP LaserJet 4250 work. So after bit peicing together information from different positions and some experiences, I managed to save my LaserJet bricks! Looks like I'll be solving my own number here haha. I'd be very happy if someone with experience could provide the answers well! Thank you.

I tried to find the answers to all these myself, but HP doesn't seem to provide a lot of detailed documentation on works of the firmware via Compact Flash process. However, if she is not the only way, is there an easier way to get the firmware on the card? For example, can I just format the card in FAT32 and copy the file to the RFU firmware to it and start the printer from him? Or the use of HP does it's own file system that is not readable on a PC? Also, would it be possible to use dd and simply copy the RFU directly on the card device believed himself (no file system) and boot from that? So that raises the question, is it possible to insert my own blank Compact Flash card in a HP LaserJet 4250 work and copy the firmware the logic board to the map image by using the printer control panel? I guess it would be the only way, if necessary, to get the firmware on the card. What I have is another HP LaserJet 4250 in working condition. However, I don't have such a card to clone. Judging by what I read on another post on the forum ( ), it seems possible to use a Unix/Linux utility such as JJ to clone another job Compact Flash card with preloaded firmware. I was wondering if it is possible to use a Type I, 128 MB Compact Flash card I have handy and load the firmware above myself using a USB Compact Flash card reader/writer. Looks like a foolproof solution, but I would like to save my company some money if possible. While doing some research, I read it is possible to buy a 32 MB CompactFlash card with preloaded firmware ( ), put the jumper pin on the logic board to boot from it and then re-flashing the firmware on the card. The screen no longer lights upward when turned on (although I can hear the internal working mechanisms which is a good sign). I had no choice but to cycle the power and hope for the best, but unfortunately it was bricked.
