3) Remove the two screws
4) Loosen the screw
remove the cylinder motor mounting
Note: The hexagonal wrench (VHJ-0113) is 2mm
diagonally. It is provided with the servicing
tool upper drum fitting tool kit (VHJ-0112).
5) Remove the upper cylinder assembly
.
The spacer

ASSEMBLY NOTES:
1. Adjustments are required when attaching the cylinder
motor mounting
. As shown in Fig. 3-5-2, face the
protruded side of the cylinder motor mounting
downwards, and with the hexagonal wrench pressed
to screw
, adjust the position of the cylinder motor
mounting
in the direction of the screw
state, hold the cylinder motor mounting
upper drum fitting tool (VHJ-0112) and tighten the
screw
with the hexagonal wrench.
2. When attaching the rotor
adjusted to that of the upper cylinder assembly
shown in Fig. 3-5-3, attach so that the hole
upper cylinder assembly
are on the same side.
3. Tighten the two screws
and the two screws
a torque of 2.5 to 3.5 kg/cm.
4. Be careful that the tape path surface of the cylinder
(drum) does not scratch or become dirty.
If it becomes dirt, clean.
5. After attaching, refer to "4-3. Tape path adjustment"
