6.9 ADJUSTING THE CLEARANCE OF THE PAPER FEED
SECTOR GEAR STOPPER
Purpose: To ensure that the paper feed roller starts rotating when the paper
feed solenoid turns on and stops rotating when the paper feed
solenoid turns off.
Adjustment Standard: See the above illustrations.
1. Remove the rear cover.
2. With a 10 mm spanner, gradually turn the shaft [A] counterclockwise.
3. When the sector gear [B] fully turns clockwise, make sure that the
clearance between the pin [C] and sector stopper [D] is between 0.1 and
0.3 mm.
4. If it is not, loosen the hexagon nut [E] and adjust the clearance by shifting
the sector stopper [D].
5. Push down the plunger of the paper feed solenoid [G] by hand. Make
sure that the clearance between pin [C] and stepper [D] is between 0.1
and 0.5 mm.
