QMS 1660 Print System Reference 6-78
4 Set the PC’s baud rate to 38400 by typing
modex.exe
↵
modex # 38400 n 8 1
↵
where # is 1-4. See the MODEX.DOC file for more information on
this program.
5 Turn on the printer.
6 When 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.
