A9 Document Handler Rap - Xerox 3001 Service Manual

A9 Document Handler RAP
Procedure
The status code A9 will be displayed i f the
document does not reach the Front
Document Sensor.
Enter the code [37] t o check the Front
document sensor.
NOTE: The Film
LED
will be lit when the
sensor is blocked.
This could occur if the actuator that blocks
the Front Document Sensor is binding. This
could also occur i f there is a problem with
the Document Drive Motor or the Document
Drive Motor PWB.
Q
The circuit diagrams are on the next
three pages.
Initial Actions
Ensure that the document is in good
condition.
Ensure that the connectors for the
Document Drive Motor (A1 1 P2) and
Drive Motor PWB(A11P1) are seated
correctly.
Check the actuator of the Front
Document Sensor for damage or
binding.
Check the document path for
obstructions and the Transport
Platen and the platen for damage
and for correct installation.
Check the document Drive Belt and
pulleys for damage and for the
correct installation.
Actuate the Front Document Sensor (44).
The Film LED goes on then off when the
sensor is actuated.
I
Go t o FLAG 2 and check the wiring for an
open circuit.
I
If there i s no open circuit, replace the
Front Document Sensor (44).
I
If the problem persists, replace the
Controller PWB.
inter Special Test
[30]
t o cycle a document
through the Document Handler. The
Document cycles properly through the
Document Handler.
The Document Drive Motor turns.
Disconnect the Document Drive
Motor Connector (A1 1 P2) from the
Drive Motor PWB (A1 1 PI). Refer t o
Note 2 and check the resistance of
the motor. The check is good.
I
Replace the Document Drive
Motor (Mot 4).

A B C
Go t o FLAG 2 and check the wiring
for an open circuit. If there is no
open, replace the Document Drive
Motor PWB (A1 1). If the problem
persists, replace the Controller PWB.
Refer back t o the Initial Actions. If the
problem persists, replace the Document
Drive Motor PWB (A1 1). If the problem
persists, replace the Controller PWB.
The problem could be an intermittent Front
Document Actuator or Sensor. Refer back
t o the Initial Actions section of this RAP. If
the problem persists, replace the Front
Document Sensor.
