Adjustment Procedures
Installing Software
Flash memory is contained in one or two single in–line memory modules
(SIMMs) located on the controller board. Printer emulation and operating
system software are loaded into flash memory at the factory, but you will
install software in the following situations:
♦ The customer needs to upgrade printer software
♦ The customer needs different emulation software
♦ You have replaced the controller board
♦ You have added or replaced flash memory
Emulation and operating system software are stored as a compressed file on a
3.5 inch, double–density floppy diskette. The file is “executable”: you will
expand it, convert it to binary, and copy it into printer flash memory with a
single command.
1. Make a printout of all saved configurations. (Refer to the Setup Guide.)
(Installing new software erases all saved configurations. You will use the
printouts to restore printer configuration.)
2. Connect the parallel data cable to the default parallel port (LPT1) of an
IBM or IBM–compatible personal computer using the PC–DOS or
MS–DOS operating system.
NOTE: You can connect the cable to the LPT2 port if the LPT1 port is
already in use. You can also download software through the printer
serial port. (The serial port is hard–wired at 9600 baud, 8 data bits, 1
stop bit, no parity.) The download commands are different if you
use these ports, as described in the note after step 12.
3. Connect the parallel data cable to the parallel port of the printer.
4. Plug the AC power cord into the printer and the power source.
5. Power on the personal computer.
6. If the computer is running Windows 3.x, double–click on the MSDOS
icon to obtain a DOS prompt.
7. Insert the emulation or upgrade diskette into diskette drive A (or B) of
the personal computer.
