4 Downloading Firmware
There is 128 MB of FLASH memory on the controller board. The printer
firmware which includes printer
control languages (the “emulations”), the
engine control, and printer operating system software are loaded
into FLASH
memory at the factory, but there are occasions when you may have to load
this software:
Firmware upgrade to a newer level
Changing to a different firmware type (e.g., TN 5250 or Postscript/PDF).
Replacing a controller or reloading firmware if FLASH becomes corrupt.
Once you have the target firmware copied onto your local PC or SD card, you can employ one of the
various download methods presented in this
section. Downloading firmware can be accomplished through
any host IO
installed on the printer, but may not be valid for all methods.
IMPORTANT The target firmware must be consistent with the options present in the
controller Security Key. Otherwise, the firmware download will be prevented.
With exception to the manual two-key and manual three-key power-up sequences, downloading new
firmware does not require the user
to put the printer into any special mode. Now downloading
methods are
employed when the printer is ONLINE and ready to
receive data. This makes the download procedure
easy.
FLASH is used to store the firmware, but it also contains a file system that
holds System and User Flash
Files. User Flash Files consist of downloaded
fonts, logos, forms, setup files, feature files, CST files, and
files that are
specific to the user’s setup or application. These files are either preserved or
deleted based
on the download method used as shown in Table 7 on page 209.
IMPORTANT Regardless of download method, any saved configurations will be
erased.
Before starting a download procedure, be sure that you have
printed or saved
configurations on your host computer or using PrintNet Enterprise Suite so
they can be
restored after the download process is complete.
NOTE: When the firmware download has completed, the FLASH memory will automatically be
optimized to maximize the amount of available FLASH memory.
