(3) Lower drum ass'y
Tighten the FPC mounting screw to the lower drum ass'y. The screw
tightening torque must be 0.08N·m (tighting torque 0.8kg·cm). (Fig-
ure 6)
(4) Upper drum ass'y
After fitting the gap shim which was removed when the upper drum
ass'y was dismantled to the shaft of lower drum ass'y, fit the upper
drum ass'y. (Figure 3)
At this time slightly turn the upper drum ass'y by hand to ascertain that
RTr does not scrape. If scrape is found, replace the gap shim with the
gap shim packaged together with the replacement upper drum ass'y.
(5) Drum motor stator
Fit the motor stator to the shaft. Then, apply the preliminary pressure
0.07N·m (0.7kg) to the motor stator, tighten the stator mounting
screw. The tightening torque must be 0.15N·m (1.5kg·cm).
Install the stator so that the chassis line is nearly parallel with the
motor stator straight section when it is installed on the chassis.
(Figure 9)
(6) Drum base
Align the positioning pin, and tighten the screws (3 pcs.).
(7) Drum ass'y
Install the drum ass'y on the main chassis, and tighten the screws (3
pcs.).
(8) Tape guide
Align the positioning pin, and tighten the screw (one pc.).
5-5-5. Phase matching
