CHAPTER 5 TROUBLESHOOTING

IV. VARIABLE RESISTORS (VR), LIGHT-EMITTING

DIODES, AND CHECK PINS BY PCB

Of the variable resistors (VR), light-

emitting diodes (LED), and check pins used in
the machine, those needed for servicing in the
field are discussed.

Caution:

Do not touch those VRs and check pins
not discussed herein. They are for the
factory, and require especial instruments
and high accuracy.

A. ADF Controller PCB

· Check Pins on the ADF Controller PCB

Normal Operating Mode

Test Mode by DIP SW

For a guide to LED indication in test mode,

see V.C. "Using the DIP Switch."

Caution:

Some LEDs emit light even when they
are off because of leakage current. This is
a normal condition, and must be kept in
mind.
