So since I could not get the PLT firmware,.  I use a good HDD of designjet T610 and convert it to z2100.  How? I installed the HDD on my z2100, off and on few times, run diagnostic , eeprom was copied to HDD but still running TJ6 firmware.  I ran ftp and did some adjustments..  then power off and on.  Machine boot to ready but will not print anything, showing error 79:04 with description of pen size 0 error. Which I understand it because of the firmware TJ6 running on z2100 machine.   So I  configure the lan with an external lan card, installed the hp utility on my system, it detected the IP address of the machine. I then try to upgrade the firmware via the firmware tab, I tried this like over 40 times before the web page open, a few partial network disconnection and reconnection trick works, the firmware page opens, then I was able to upgrade to TR8 firmware.  Which works well.  Machine was able to print.. .   But I did all dis on a another hp DESIGNJET z2100 44".  So on taking the formatter and HDD to my hp designjet z2100 24", it gives error 59: meaning nvm management error formatter mismatched.  So I quickly know that the printmech info was different from the HDD I install.  So that is the current issue now.. 

So today I plan to return the formatter and HDD back to the z2100 44" and rerun the firmware so upon installing the firmware @100% and during reboot, I will power off the machine and  remove the printmech and install the one on the 24" by doing this, I believe the blank HDD will get the info of the 24" printmech and continue booting..  if these works, I may not need to buy hdd again..  thanks

So I did the second upgrade without letting the HDD boot after sending the firmware to the 44" machine.  After installing the HDD back to the 24" machine..  it still gives error 59:01.  

So my though is that , the firmware I was uploading was TR8-12.0.0  for revision A and C.   But the the 24" machine is Q6675D.  Which is revision D.   So I want to now try and reinstall the correct firmware of TR8-13.0.0.1 for revision D.  Hope it works..  stay tuned
