I think you have a bad memory module, or a bad system board, did it happened after a power loss or power surg??? (common for these printers)

Have you tried to reset it to factory default (according to service manual)

Good luck!

Laserjet 4250 printer showing error message 000MB Will not start. Tried holding down check symbol. Nothing happened. Cannot clear problem


Either your memory is bad on the printer or the formatter is bad. Remove the right side cover and open the metal cage for the formatter and reseat any memory chips you find there. Make sure the printer is unplugged from power first.

A problem with HP Laserjet 2420


X PRINTER ERROR A firmware error occurred 1. Press CANCEL JOB to clear the print job from the printer memory. 2. Turn the printer off, and then turn the printer on. 3. Try printing a job from a different software application. If the job prints, go back to the first application and try printing a different file. (If the message only appears with a certain software application or print job, contact the software vendor for assistance.) 4. If the message persists with different software applications and print jobs, disconnect all cables to the printer that connect it to the network or printer. 5. Turn the printer off. 6. Remove all memory DIMMs or third-party DIMMs from the printer. (Do not remove the firmware DIMM in the lowest DIMM slot.) 7. Remove all EIO devices from the printer. 8. Turn the printer on. 9. If the error no longer exists, install each DIMM and EIO device one at a time, making sure to turn the printer off and back on as you install each device. 10. Replace a DIMM or EIO device if you determine that it causes the error. 11. Remember to reconnect all cables that connect the printer to the network or computer. 12. If the error persists, replace the firmware DIMM. 13. Replace the formatter. This error is usually caused by a bad formatter board.

Hp 2420 displays 53.07


The 53.07 error relates to Memory. Turn the printer off. Remove the right side cover. Remove any and all DIMM (memory) cards and printer/network cables from the formater board. The memory DIMMS are located behind the metal cover. Remove any Jetdirect Cards installed into the EIO slot on the back of the formatter.

With all accessories removed power up the printer and see of it comes to ready. If not, you need a formatter board. If it does come to ready, power it off and plug one peice that you removed back in and try again. Keep adding one at a time and powering up again until the error returns. When you get the error, the last added back onto the machine is the problem.

Here's a copy of the service manual to help with disassembly, troubleshooting and part numbers for ordering.
