Item Description
LED1 RF Tag Read Write, Upper - Blinks rapidly during RF Tag Read or Write.
LED2 RF Tag Read Write, Lower - Blinks rapidly during RF Tag Read or Write.
LED3 RF Tag "Happy" - Blinks approximately once a second. When the Machine Control System
(MCS) is reflashing the RF Tag MICROPROCESSOR, this LED will be on constantly. If
the MCS is not reflashing the MICROCPROCESSOR and the LED is not blinking, the
MICROPROCESSOR is not functioning.
LED4 FPM MASTER MICROPROCESSOR "Happy" - Blinks approximately once a second
during normal operations. When the MCS is reflashing the FPM MASTER
MICROPROCESSOR, this LED will lock either ON or OFF for approximately 4 seconds.
In some circumstances, the FPM MASTER MICROPROCESSOR takes the responsibility
of reflashing the STEP MOTOR DRIVER (SMD) MICROPROCESSOR (U9 to U14).
When this is taking place, the FPM "Happy" LED will blink approximately 4 times a
second. This process can take up to 3 minutes, during which time normal printer operation
will be suspended. If no reflashing is taking place and the LED is not blinking, the
MICROPROCESSOR is not functioning.
LED5* LIFT_HOME UPPER - When lit, upper FILM SUPPLY PICKUP BAR is at home (up).
