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.

On powerup the HP Laserjet 2420 display shows 000MB ********** ******************* Bad boot DIMM?


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!

My printer shows memory error on its screen why?


Mem test failure replace Dimm 0 or Mem test failure replace Dimm 1
If either of the are the messages displayed, the problem lies with the mother board (formatter).
DIMM 0 = On Board Memory - cannot be changed. DIMM 1 = Add On Ram - Can be Changed
Make Sure the printer firmware is up to date FIRMWARE
Most Likely the formatter board would require replacing.

I have a HP LaserJet 2420dn Printer the problem is, it takes too long a time print a document


The easiest solution for these printers is to upgrade the standard memory to at least 128Mb or 256MB. Memory is relatively cheap and adding it will speed printer functions greatly.

HP Laserjet 2420dn will not print and is displaying message '49.FF04 service error'


Does the error display when printing a particular job, or anything that you print? If you have extra memory installed, remove it. Power up and try again. If it won't clear replace the formatter
