3. OPERATIONS AND TIMING
When the lens X motor is at rest, the lens X
motor hold signal (LX-HOLD) is generated and a
voltage lower than the voltage used to rotate the
lens is applied by way of applying brakes.
Caution:
Be sure to disconnect the power plug
before moving the lens.
A low voltage is applied to the lens motor
even in standby or when the power is off
(except in auto power-off mode); moving
the lens without disconnecting the power
plug can cause damage.

4. Moving the Lens
a. At Power-On
When the power switch is turned ON, the lens
X motor (M9) rotates, and the lens keeps moving
until the signal plate on the lens housing blocks
the lens X home position sensor (Q2).
Then, the lens Y motor (M10) rotates, and the
lens keeps moving until the signal plate on the
lens mount blocks the lens Y home position sen-
sor (Q3).
When the signal plate blocks the home posi-

tion sensor, the X motor and the Y motor rotate in
reverse, and the motors will stop when the lens
housing is positioned where A4 copies in Direct
may be made. (See I of Figure 3-205.)
