Adjusting the Position of the
Paper Deck Pick-Up Roller
Releasing Solenoid (SL8001)

Install the solenoid where the paper deck pick-

up roller is 4.0 ±1 mm from the surface of the paper
when the plunger of the solenoid is pushed in.
(Keep one sheet of paper on the paper deck lifter.)

Adjusting the Pressure of the
Paper Deck Separation/Feed-
ing Roller

If pick-up faults or double-feeding occurs in the

paper deck, change the position of the spring
hooked on the retard stay.
a. If pick-up faults occur, increase the pressure.
b. If double-feeding occurs, decrease the pres-

sure.

Standard (movement
to the next hole results
in a change of about
50 g pressure.)

Decrease the
pressure.

Increase the
pressure.
