LED Color Description
When
Lit
CR1 Red General purpose software
programing (during booting
blinks once)
CR2 Red General purpose software
programing (during booting
blinks once)
CR3 Green General purpose software
programming (during boot-
ing blinks once)
CR4 Green General purpose software
programming (during boot-
ing blinks once, then three
times, then stays ON)
CR10 Red Transport Motor Current
Limit
CR12 Green USB connection detected
CR13 Green Configuration Complete for
the FPGA (Field Program-
mable Gate Array - U14).
The FPGA receives its
configuration program from
the processor and must
be programmed on every
power up.

Normal State
LED is lit if either
the transport mo-
tor or the shuttle
motor is running
LED is lit when
printer is printing
LED not lit
LED is lit
LED is lit from
time-to-time

when USB is
active
LED is lit (FPGA
programming is
complete)
LED lit when
sensor is blocked
Error State
LED stays lit
(indicates a
board/software
problem)
LED stays
lit under ALL
printer states
(indicates a
board/software
problem)
LED stays lit
(indicates a
board/software
problem)
LED stays off
(indicates a
board/software
problem)
LED stays lit (in-
dicates shuttle
motor over-cur-
rent detected)
LED stays off
after connecting
a USB device
(indicates a bad
USB connec-
tion; may be
interface board
in printer, cable
or USB device
on other end)
LED stays off
(indicates a
board/software
problem)
