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.
Jetlink protocol
(interface used to hook up output devices; external to printer)
No version checking.
DC controller
(internal to printer)
duplexer
input external trays

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.
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.
