LaserWriter Plus: Double-Blinking Status Light



I'm having a problem with a LaserWriter Plus (recently upgraded) connected
to an IBM. The "Busy" status light sometimes has an uncharacteristic
"double blink," as opposed to the normal "single blink" when processing
jobs. Also, when PostScript jobs from some applications are completed, the
status light does not turn off, but instead starts to "double blink." What
does a "double blinking" status light mean?

The double-blinking light is normal. In certain instances, the yellow
light continues to flash, indicating it is processing a job. This is most
evident when you do a manual feed and insert the paper before the red
jam-light comes on. Also, if an end-of-page command is not sent when
printing from an MS-DOS machine, the lights continue to flash.
