CHAPTER 14: MASTER MAKING SECTION
[ 14 - 39 ]
7. Master Positioning Sensor sensitivity adjustment
Make following adjustments after replacing Master positioning sensor.
Checks and adjustment
(1) Pull out the Master making unit. If master material is set in the unit, rewind the master material back on
the master roll, so no master is under the Master positioning sensor.
(2) Detach the Master-making unit front cover.
(3) With the machine power ON, using a multimeter, measure the voltage between pin No.1 (+) and pin No.3
(-) of connector (CN6) of the Master making PCB.
(4) Confirm that the measured voltage is between 0.8 volt and 1.2 volts.
(5) If the voltage is not within the above given range, slowly and gently rotate both volume dials VR1 and VR2
all the way in the clockwise direction until the dials stop.
(6) Slowly rotate the dial VR1 (rough adjustment dial) in the counterclockwise direction until the voltage
becomes about 2 volts.
(7) Then slowly rotate the dial VR2 (fine adjustment dial) in the counterclockwise direction until the voltage
comes down to the correct voltage setting within 0.8 volt to 1.2 volts. (If possible, aim for 1.0 volt.)
