to"Disassembly"(see page 44).

During replacement, handling precautions shall be

taken to prevent an electrostatic discharge(protection

by a short pin).

2. During disassembly, be sure to turn the power off

since an internal IC might be destroyed when a con-

nector is plugged or unplugged.

3. Please checking the grating after changing the ser-

vice pickup unit(see page 32).

4. Since these screws protects the mechanism during

transport, be sure to affix it when it is transported for

repair, etc.

Decimal points for resistor

and capacitor fixed values

are expressed as :

2.2 2R2

0.022 R022

←

The >mark found on some component parts indicates

the importance of the safety factor of the part.

Therefore, when replacing, be sure to use parts of

identical designation.

Symbol indicates a resistor.

No differentiation is made between chip resistors and

discrete resistors.

NOTE :

Symbol indicates a capacitor.

No differentiation is made between chip capacitors and

discrete capacitors.
