The process for remotely upgrading firmware involves three steps:

Version Checking
JetDirect inside (JDI)
Does version checking.
Upgrades if the firmware version is newer; this means it will not
rewrite or upgrade if the firmware is the same or older.
This becomes an issue if the current firmware is corrupt.
Because the firmware version may be the same even though
it may be corrupt, the firmware will not rewrite because it is the
same version.
To update corrupt firmware with the same RFU version, use
the nodebug bundle of firmware, then update using the correct
firmware bundle.
Fax Modem
Does version checking.
The firmware updates if the RFU is different from what is
currently on the component. The firmware can be updated if
the RFU is older or newer than the current firmware version.
Will not upgrade if firmware version is the same. The same
version does not rewrite because of speed.
This becomes an issue if the current firmware is corrupt.
Because the firmware version may be the same even though
it may be corrupt, the firmware will not rewrite because it is the
same version.
Formatter
No version checking.
The formatter firmware updates if there is a formatter bundle
on the RFU, and is not dependant on what version of firmware
the formatter is currently using.
Copy control board (CPB)
No version checking.
Scan control board (SCB)
Does version checking.
Upgrades if the firmware version is newer; this means it will not
