A red LED on the rear panel of the Bulk Ink Supply, and an optional beacon, indicate the sys-
tem’s operational status:
○
LED/beacon is off - system is operating normally.
○
LED/beacon is on steady - normal system operating pressure (5 psi) was not achieved
after 15 seconds of continuous pressure pump operation and the pump has shut down. It
indicates that the ink cartridge is empty and needs to be replaced. The pump will automat-
ically restart when the cartridge is replaced or power is cycled off and on.
○
LED/beacon is blinking rapidly - the system has experienced a rapid loss of pressure,
possibly due to a break in an ink line, and has shut down.
○
The LED repeatedly blinks rapidly for one second, then goes out for one second, blinks
for one second, goes out for one second, etc.; the beacon continuously blinks rapidly with
one second "off" periods - indicates a missing ink cartridge or the cartridge is not being
detected by the system.
