Format Disk and Partial Clean functions
NOTE: Only for products with an optional hard-disk drive (HDD) installed).
Active and repository rmware locations
The rmware bundle consists of multiple parts. The main components are the Windows CE Operating System
and the printer/peripheral rmware les.
There are two locations/partitions on the hard drive where the rmware components are stored:
●
The Active, where the operating system and rmware currently are executing.
●
The Repository, the recovery location.
If the Active location is damaged, or a Partial Clean was performed, the printer automatically copies over the
OS and rmware les from the Repository location and the printer 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
rmware to the printer in order for it to function again.
CAUTION: The Format Disk option performs a disk initialization for the entire disk. The operating system,
rmware les, and third party les (among other les) will be completely lost. HP does not recommend this
action.
Partial Clean
The Partial Clean option erases all data from the partitions, except for the rmware repository where a
backup copy of the rmware le is stored. This allows the disk drive to be reformatted without having to
download a rmware upgrade le to return the printer to a bootable state.
Characteristics of a Partial Clean
●
Customer-dened settings, third-party solutions, rmware les, and the operating system are deleted.
●
Rebooting the printer restores the rmware les from the Repository location, but does not restore any
customer-dened settings.
●
For previous HP products, a Hard Disk Initialization is similar to executing the Partial Clean function for
this printer.
CAUTION: HP recommends backing-up printer conguration data before executing a Partial Clean to retain
customer-dened settings (if needed). See the Backup/Restore item in the Device Maintenance menu.
Reasons for performing Partial Clean
●
The printer continually boots up in an error state.
NOTE: Try clearing the error prior to executing a Partial Clean.
●
The printer will not respond to commands from the control panel.
●
Executing the Partial Clean function is helpful for troubleshooting hard disk problems.
