-IDS Ink and Vacuum Control PCB
LEDs:
LED1:
NOT DEFINED.
LED2:
Red; indicates a print head is signaling that the print
head reservoir is low and the ink out timer has expired.
LED3:
Green; indicates a print head is signaling for the vacuum
pump to turn on.
LED4:
Green; indicates a print head is signaling for the liquid
pump to turn on.
LED5:
Red; indicates that the waste bottle is full.
LED6:
Red; turns on, off, and flashes with the beacon. Off
indicates ink is OK, on indicates ink is low, slow flash
(1 Hz) indicates ink is out, and fast flash (6 Hz) indicates
that the waste bottle is full or the pump was turned on for
more than 10 seconds.
LED7:
Yellow; indicates ink is low in the S
MART
-IDS reservoir.
