Phaser 6115MFP Multifunction Product Service Manual 3-9
Error Codes and Messages
Using the Troubleshooting Procedures
1.
Applicable Status Code(s)
lists the error message(s) addressed by each
troubleshooting procedure.
2.
Applicable Parts
and
Wiring and Plug/Jack References
assist you in
locating information available for a particular part or procedure.
3. Follow each
Step
in a troubleshooting procedure sequentially in the order
given until the problem is fixed or resolved.
4. The
Actions and Questions
box instructs you to perform a certain action or
procedure. Also included are precautions and/or additional procedures
you must follow to isolate the problem.
5. Some actions are followed by a question. If your response to the question
is
Yes
, then follow the instructions for a
Yes
reply. If your response to the
question is
No
, then follow the instructions for a
No
reply.
6. Note that two types of photo sensors are used: photo-reflective and
photo-receptive. Photo-reflective sensors use light reflected back from an
object to detect its presence or absence. Photo-receptive sensors use an
actuator or the object itself to block the light path to detect an object or
condition.
7. Troubleshooting procedures frequently ask you to take voltage readings
or test for continuity or resistance at certain test points. The
Wiring and
Plug/Jack References
table provides pointers to the diagrams that provide
this information.
8. Troubleshooting procedures often ask you to replace a printer component.
When instructed to replace a non-spared component and that component
is part of a parent assembly, replace the entire parent assembly.
Measurement Techniques
1. Unless indicated otherwise, the instruction “switch On printer power”
means for you to switch On printer power and let the printer proceed
through Power On Self Test (POST) to a ‘Ready’ condition.
2. Conventions used in this manual to represent connectors.
3. When instructed to take voltage, continuity or resistance readings on
wiring harness, proceed as follows; Check P/J 232–1 to P/J 210–5 by
placing the red probe (+) of your meter on pin 1 of P/J 232, and place the
black probe (–) of your meter on pin 5 of P/J 210.
4. When you are instructed to take resistance readings between “P/J 232
<=>
P/J 210” (without specified pin numbers), check all pins. Refer to the
section "Wiring Diagrams" for the location of all wiring harnesses and
pins.
5. When you are instructed to run a test, run the Service Diagnostics test
associated with the component being examined.
6. When you are instructed to take a voltage reading, the black probe (–) is
generally connected to a pin that is either RTN (Return) or SG (Signal
Ground). You can substitute any RTN pin or test point in the printer, and
you can use FG (frame ground) in place of any SG pin or test point.
7. Before measuring voltages make sure the printer is switched On, the
Imaging Unit and the paper trays are in place, and the interlock switch is
actuated, unless a troubleshooting procedure instructs otherwise.
