+5 VDC Measurement
1 Unlock, unscrew, and remove the FPR door.
2 Using a DC voltmeter, measure the +5 VDC between the GND test point and the right side of
R26, both located on the FPR CPU PCB (
Figure 9-5 ).
3 The acceptable voltage range is +5.0 to +5.1 VDC, but try to adjust it as close as possible to
+5.0 VDC.
Note: There is an access hole in the power supply bracket to facilitate adjustment without
disassembly.
