C1.O1l C2.071 C3.07 Media Feed
RAP
The status code C1.O1 or C2.07 or C3.07 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 1
Position Sensor is blocked and not blocked,
causing the sensor signal to change state.
The logic detects a change in the state of the
Roll 1 Position Sensor signal.
C1.O1
lndicates that the logic detected
that either media was not fed to, or
media was not fed or rewound
past, the Roll
1
Position Sensor. The
sensor signal does not change state
from a HlGH to LOW or from a LOW
to HIGH a s the media is being fed
from Roll 1.
C2.07
lndicates that the logic detected
that media was not fed to the Roll 1
Position Sensor. The sensor signal
does not change state from a HlGH
to LOW as the media is being fed
from Roll 2.
C3.07 lndicates that the logic detected
that media was not fed to the Roll
1
Position Sensor. The sensor signal
does not change state from a HlGH
to LOW as the media is being fed
from Roll 3.
The problem may occur if there is a problem
with the roll drive motor or the motor
control circuitry.
Initial Actions
Open the front doors and pull ou t the
Top Drawer. Check the media path
for obstructions.
Remove the rear covers and the Roll 1
Position Sensor (Q1) from the rear
frame. Clean the Roll 1 Position
Sensor by wiping the face of the
sensor with a clean cloth. Reinstall the
Sensor.
Check that the connectors for the Roll
1 Position Sensor (Q1 PI) and the
Control PWB (A3 P309) for damage.
Ensure that the connectors and pins
are seated correctly.
Procedure
Enter the code [0707] in order to check the
Roll 1 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 Top Drawer and ensure that
media is not positioned in the sensor
window. Close the drawer, a
(01)
i s
displayed.
Pull out the Top Drawer and pbsition 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, do the
following:
When C1 .O1 is displayed, go to the 7.1
Roll
1
Feed RAP.
When C2.07 is displayed, go to the 7.2
Roll 2 Feed RAP.
When C3.07 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 1 Position Sensor and the Control
PWB for an open circuit or a short circuit to
ground.
If there is no open circuit or short circuit,
replace the Roll 1 Position Sensor (Q1).
If the problem persists, replace the Control
PWB (A3).
