HP Recommended
Product: HP LaserJet Enterprise M607dn

Hi HP Support Team,

I’m having trouble installing an official HP 320GB encrypted hard drive (purchased as an optional accessory) on my HP LaserJet M607 printer.

Here’s what I’ve done:

  1. Installed the HP-branded 320GB mechanical drive.

  2. Followed the manual: Reflashed the firmware via USB in PreBoot mode.

  3. Consistently get Error 90.00.02, and the printer fails to power on.

I’ve tried troubleshooting both ways:

  • With the original EMMC chip removed

  • With the original EMMC chip in place
    ...but the same error (90.00.02) appears after reflashing.

I’m puzzled since HP’s documentation lists this drive as a compatible upgrade. Could you help diagnose why it’s failing? Appreciate any guidance!
