E2.01 Media Transportation
RAP
(212193)
The status code E2.01 is displayed when the
logic detects that the media is jammed in the
registration area of the Media Transport.
The media that is moving through the Media
Transport, alternately blocks and clears the
Media Registration Sensor, causing the
sensor signal to change state. The logic
detects a change in the state of the Media
Registration Sensor signal.
E2.01
Indicates that the logic detected
that :
(a) the media is blocking the Media
Registration Sensor
at
Power On.
The sensor signal is LOW when the
Power On (1) switch was pressed.
(OR)
(b)
during the run mode, the media
was not driven past the Media
Registration Sensor. The sensor
signal did not change state from
LOW to
HIGH
as the media was
being fed.
The problem may occur if there is a problem
with the Media Transport mechanical
components, the Transport Drive Motor, or
the motor control circuitry.
NOTE: If the media
is
jammed in the Media
Transport, ensure that the entire sheet of
media is removed from the copier.
NOTE: The component locator drawings and
the circuit diagrams are located on the
following pages.

Lower the Sheet Feed-in Shelf and the
Latching Cover. Check the Media
Transport for a media jam. Remove
any obstructions In the media path.
Clean the Media Registration Sensor
by wiping the face of the sensor with a
clean, dry cloth.
Check the Media Transport connector
(A21 PI J1) for damage and ensure
that the connector and pins are seated
correctly.
Check the Control PWB connector for
the Media Registration Sensor (A3
P305) for damage and ensure that the
connector and pins are seated
correctly.
Check the Media
Exit
Guide on the
Cutter Assembly for damage (burrs on
the metal bracket; bent, damaged or
misaligned plastic guide).
With the Sheet Feed-in Tray and the Latching
Cover in the lowered position, place a clean
strip of bond media over the Media
Registration Sensor.
The display changes from (01) to (00) when
the sensor is covered.
Go to FLAG 1 and check for an open
circuit or a short circuit to ground in the
wires to the Media Registration Sensor.
If there is no open or short circuit,
replace the Media Registration Sensor
(QO.
If the problem persists, replace the
Control
PWB (A3).
