Voltages Resistances and Tolerances
Introduction
Voltages Resistances and Tolerances
For AC power specifications, refer to
GP 22
Electrical Power Requirements.
DC Voltage Levels and Tolerances
DC Voltages should be measured between an available test point and a machine ground.
Table 1
shows the range of the common voltages.
Non-standard voltage levels will be quoted on the relevant circuit diagram. All other voltage lev-
els are plus or minus 10%.
Resistance Tolerances
All resistance measurement tolerances are plus or minus 10%, unless otherwise stated in the
procedure.
DC Signal Nomenclature
Figure 1
shows the signal nomenclature used in this manual.
Figure 1 Signal Nomenclature
Table 2
shows the signal tolerances.
Non standard signal tolerances will be quoted on the relevant circuit diagram.
NOTE: The logic level shown with the signal name will be the actual signal as measured with a
service meter. This will not necessarily be the same as the logic state shown on the diagnostic
screen.
Samples of RAP reference text
Throughout the manual there are linked references that extend the diagnostic procedure or
add more information.
Go to
Flag 1
. Check Q08-300. Refer to:
NOTE: This links to a particular part of the circuit diagram within a RAP.

NOTE: The P/J links to the connector location on the PWB in a circuit diagram.
NOTE: The PWB links the connector to the pin layout on the PWB, referenced in the Wir-
ing Diagram section.

Install new components as necessary:
•
Tray 1/2 feed sensor,
PL 7.30 Item 24
.
NOTE: This links to the parts list. If installation of the new component is simple, the parts
list artwork is sufficient to show how the component is assembled in the machine. If instal-
lation of the new component is not simple, the parts listing will contain cross references to
repair procedures and adjustments, as necessary.
