Downloading Into Flash Memory
CAUTION
When downloading an emulation to the printer, all other
optional font files, customer-supplied logos, and setup files
will be erased. You will then need to reload these files. Before
starting a download procedure, be sure that you have all of the
necessary installation files on hand.
CAUTION
Do not interrupt the downloading process. Interrupting a
download will damage the flash memory on the controller
board and PrintNet card.
To download emulation software, as well as downloadable files for
logos, forms, TIFF, setup, and fonts to the printer, do the following:
1. If you plan to download any logo, form, TIFF, setup, or font files
into the printer, you must first use the supplied
lasr2fls
DOS
utility program to convert these files into downloadable format.
See page 101. (Emulation files require no conversion.)
2. Take the printer offline by pressing the ONLINE key.
Press the UP + DOWN keys simultaneously to unlock the
ENTER key.
3. Make a printout of all saved configurations. (Installing new
software erases all saved configurations. You will use the
printouts later to restore the printer configuration.)
NOTE: Loading flash memory does not affect the page count or
other data stored in NVRAM.
4. Set the printer power switch to O (Off).
5. If the printer is already connected to the parallel port of an
IBM-compatible computer that is using the PC-DOS™ or MS-
DOS
®
operating system, skip to step 11. If not, continue with
step 6.
6. Unplug the printer AC power plug from its electrical outlet.
7. Disconnect all data input cables from the printer interface.
