C2.01/ C3.06 Media Feed RAP
The status code
C2.01
or
C3.06
is displayed
when the logic detects that there is a media
feed problem. As media is fed or rewound
along the media path the Roll 2 Position
Sensor i s blocked and not blocked, causing
the sensor signal to change state. The logic
detects a change
in the state of the Roll 2
Position Sensor signal.
C2.01
lndicates that the logic detected
that either media was not fed to, or
media was not fed or rewound
past, the Roll
2
Position Sensor. The
sensor signal does not change state
from a HlGH to LOW or from a
LOW
to a HlGH as the media is
being fed from Roll
2.
C3.06
lndicates that the logic detected
that the media did not feed past
the Roll 2 Position Sensor. The
sensor signal does not change state
from a LOW to HIGH as the media is
being fed from Roll 3.
The problem may occur if there i s a problem
with the roll drive motor or the motor
control circuitry.
Initial Actions
Open the front doors and pull out the
Middle Drawer. Check the media path
for obstructions.

Media Feed RAP
Remove the rear covers and the Roll
2
Position Sensor (Q2) from the rear
frame. Clean the Roll 2 Position
Sensor by wiping the face of the
sensor with a clean cloth. Reinstall the
Sensor.
Check that the connectors for the Roll
2
Position Sensor
(Q2
PI) and the Control
PWB (A3 P309) for damage. Ensure that
the connectors and pins are seated
correctly.
Procedure
Enter the code
[07081
in order to check the
Roll 2 Position Sensor. The Control Panel will
display a
(01)
when the media is not sensed
and a
(00)
when the media is sensed.
Pull out the Middle Drawer and ensure that
media
is
not positioned in the sensor
window. Close the drawer; a
(01)
i s
displayed.
Pull out the Middle Drawer and position the
media so that the media is located in the
sensor window. Close the drawer; a
(00)
is
displayed.
If a (01)
is displayed without media in the
sensor window and a (00)
is displayed with
media in the sensor window,
db
the
following:
When
C2.01 i s
displayed, go to the
7.2
Roll 2 Feed RAP.
When C3.06
is displayed, go to the
7.3
Roll
3
Feed RAP.
If the display does not change from (01) to
(00)
when the media is positioned in the
sensor window, continue with this
procedure.
Go to FLAG 1 and check the wiring between
the Roll 2 Position Sensor and the Control
PWB
for an open circuit or a short circuit to
ground.
If there i s no open circuit or short circuit,
replace the Roll 2 Position Sensor
( 4 2 ) .
If the problem persists, replace the Control
PWB (A3).
