HP LaserJet Enterprise Flow MFP M575

Active and repository firmware locations

The firmware bundle consists of multiple parts. The main components are the Windows CE Operating System and the product/peripheral firmware files. There are two locations/partitions on the hard drive where the firmware components are stored:

• The Active . where the Operating System and firmware currently are executing.
• The Repository . the recovery location.

If the Active location is damaged, or a Partial Clean was performed, the product automatically copies over the OS and firmware files from the Repository location and the product recovers.

If both the Active and Repository locations are damaged, or a Format Disk was performed, then both locations are gone and the error message 99.09.67 displays on the control-panel display. The user must upload the firmware to the product in order for it to function again.

CAUTION:
The Format Disk option performs a disk initialization for the entire disk. The operating system, firmware files, and third party files (among other files) will be completely lost. HP does not recommend this action.

Partial Clean

The Partial Clean option erases all partitions and data on the disk drive, except for the firmware repository where a backup copy of the firmware file is stored. This allows the disk drive to be reformatted without having to download a firmware upgrade file to return the product to a bootable state.

Characteristics of a Partial Clean

• Customer-defined settings, third-party solutions, firmware files, and the operating system are deleted.
• Rebooting the product restores the firmware files from the Repository location, but does not restore any customer-defined settings.
• For previous HP products, a Hard Disk Initialization is similar to executing the Partial Clean function for this product.

CAUTION:
HP recommends backing-up product configuration data before executing a Partial Clean if you need to retain customer-defined settings. See the Backup/Restore item in the Device Maintenance menu.

Reasons for performing Partial Clean

• The product continually boots up in an error state.
  NOTE: Try clearing the error prior to executing a Partial Clean.
• The product will not respond to commands from the control panel.
• Executing the Partial Clean function is helpful for troubleshooting hard disk problems.
• To reset the product by deleting all solutions and customer-defined settings.
• The product default settings are not properly working.

2. The HP logo displays on the product control panel. When the initialization counter 1/8 displays below the HP logo, immediately touch the logo to open the Preboot menu.

4. Use the down arrow button to highlight Partial Clean, and then touch the OK button.
