modex.exe

modex # 38400 n 8 1

where # is 1-4. See the MODEX.DOC file for more information on this program.

5Turn on the printer.

6When the control panel indicators stop flashing (the mes- sage window will remain blank since the printer is non-func- tional), send the new system software file SYSTEM.DL to the printer.

Type

copy /b system.dl com#

where # is 1 to 4. (/b refers to binary files.) If you’re not sure of the number of the serial port, check your PC’s documentation.

The downloading process takes about 5 minutes, depending on the size of the file and the speed of your PC. The Ready indicator blinks as the new system image is copied to flash ROM. After the updated system software has been written to flash ROM, the printer reboots with the new system image, prints a start-up page, and returns to IDLE.

»Note: The new flash image does not erase the old image until the printer verifies that the new image is valid.
