Code display Detection timing
Error : Clamp motor locked
Within 3 seconds after the clamp motor starts rotating,
the clamp sensor 1/the clamp sensor 2 does not detect
that B mode/C mode is entered.
E012
Error : Scanner stepping motor locked
When moving the slider from end to end, the slider position
sensor 1/the slider position sensor 2 does not detect that
the slider reaches the desired position within 6 seconds
after the scanner stepping motor starts rotating.
E013
When moving the slider from the position other than the
end to the end, the slider position sensor 1/the slider
position sensor 2 does not detect that the slider reaches
the desired position within 12 seconds after the scanner
stepping motor starts rotating.
Error : Vertical registration motor locked
The vertical registration encoder sensor does not detect the
edge within 0.5 seconds after the vertical registration motor
starts rotating.
Although the vertical registration motor is rotating, the vertical
E015
registration encoder sensor does not detect the edge for 0.3
seconds.
Although the vertical registration section is moved by 1.25 x
of the maximum one-side vertical registration moving distance
back to the center, the vertical registration center sensor does
not detect that the vertical registration reaches the center.
Error : ADF stepping motor locked
E017
Write/readout to FPGA stepping controller of the
main PCB is defective.
Error : FPGA
E018
Write/readout to FPGA of the main PCB is defective.
Error : Tape dispenser cutter motor locked
Tape cutting is defective.
E020
Error : Communication with the tape dispenser
is not performed normally
E021
Communication between the main PCB and the tape
dispenser PCB is defective.
