LL.30 Cutter Fault (W/ 0 Tag /
I
MOD3I)RAP
The status code 11.30 is displayed when the
logic detects that there is a media cutter
problem. As the cutter bar rotates t o cut the
media, the Cutter Home Sensor is blocked
and not blocked by the rotating encoder
disk. The logic detects a change i n the state
of the Cutter Home Sensor signal.
LL.30
Indicates that no motion is detected
by the logic from the Cutter Home
Sensor. The sensor signal did not
change state from a HlGH to LOW
or from a LOW to HlGH as the
media is being cut.
The problem may occur i f there is a problem
with the cutter mechanical components, the
Cutter Drive Motor or the motor control
circuitry.
NOTE: If the Drive Motor fails during a copy
cycle, the media must be cut manually at the
supply roll. The media is then pulled out of
the copier from the fuser exit area.
NOTE: The component locator drawings and
the circuit diagrams are located on the next
five pages.
