5.When a procedure instructs you to test a component using Service
Diagnostics, see "Service Diagnostics" on page 4-6 for the detailed steps
and functions for testing parts, assemblies, or subsystems of the printer.

7.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.
8.Troubleshooting procedures frequently ask you to take voltage readings or
test for continuity or resistance at certain test points. The
table provides pointers to the diagrams that provide this

information.
9.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.
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.

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" on page 10-13 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.
