the continuity of the line cord and replace if
necessary.
3 Power Switch Check the continuity on the power switch. If
incorrect, replace the power switch.
4 Power Supply With the power switch turned on, verify the
voltage readings at RIP card connector (J1)
and engine board connector (J1). The RIP
card voltage at J1-1 and J1-2 should be
approximately +5 V dc at each pin. Check the
engine board connector (J1) voltage to verify
that J1-3 and J1-4 have approximately +35 V
and J1-11, J2-12 read 5 volts each.
Note: If any of the voltage readings are not
correct, replace the power supply.
