Resetting the DECcolorwriter 1000’s NVRAM
Resetting NVRAM returns all the image processor's parameters to factory defaults
except the print count (processed through the image processor) and the Adobe firmware
serial number.
To reset the image processor to its factory default values, follow this procedure:
1. Place the rear panel DIP Switch 4 in the on position (up). Place the rear panel
DIP Switches 2 and 3 in the off position (down).
2. Flip DIP Switch 1 up and back down to reinitialize the printer.
3. Observe the rear panel LED; it quickly flashes four times for 1 second and
then is off for 1 second. This pattern repeats for 10 seconds.
During the time the “quick flash” pattern is displayed, move DIP Switch 4
into the off (down) position. NVRAM will automatically reset when the
health light begins blinking at its steady one blink/second “heartbeat” rate,
indicating normal operation.
If you do not move DIP Switch 4 down during the “quick flash LED” pattern
display, then the NVRAM is not reset. If Switch 4 is down during an ordinary
power-up, then the quick flash LED pattern is not displayed and NVRAM is
not reset.
