Using the Troubleshooting Procedures
1.
Each Step in a Troubleshooting Procedure instructs you to perform a certain
action or procedure. The Steps are to be followed sequentially in the order given
until the problem is fixed or resolved.
2.
The Actions and Questions box contains additional information and/or additional
procedures you must follow to isolate the problem.
3.
When a procedure instructs you to test a component using service diagnostics,
See "Service Diagnostics" on page 3-6 for the detailed Steps and functions for
testing parts of the printer.
4.
The action is 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.
5.
Troubleshooting Procedures may ask you to take voltage readings or test for
continuity at certain test points within the printer. For detailed diagrams, refer to
the section "Plug/Jack Locator Maps" on page 10-2 and "Wiring Diagrams" on
page 10-12 for complete information on test point locations and signal names.
6.
Troubleshooting Procedures often ask you to replace a printer component. The
section "Service Parts Disassembly" on page 8-1 provides detailed Steps for
removing and replacing all major parts of the printer. The section "Parts List" on
page 9-1 details the location, quantity and part number for all spared parts of the
printer.
General Notes on Troubleshooting
1.
Unless indicated otherwise, the instruction “switch ON printer main 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 the section
"Wiring Diagrams" on page 10-1 for the location of all wiring harnesses and pins.
5.
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.
