Safety precautions when disassembling and adjusting
Always use the genuine parts specified in the manufacturer's manual as the replacement parts.
Installing a wrong or unauthorized part could cause dielectric breakdown or overload, or under-
mine safety devices, resulting in possible electric shock or fire.
Never modify the unit or mount optional components not specified by MINOLTA-QMS, Inc.
Modifying the unit or adding unauthorized components could expose the user to hazards; cause
dielectric breakdown, overload, misoperation, or other such problems; and result in electrical
shock, fire, injury, or loss of sight.
Always use the same screws when reassembling the unit. Improper screw connections could
cause looseness, dielectric breakdown, improper installation, electrical shock, or injury.
Never tamper with screws marked with red paint. Tampering with these screws could image
defects or abnormal noises.
Always check that the safety switches operate properly after servicing has been completed.
Improperly operating safety switches could result in electrical shock or injury to the user.
Periodically clean and inspect the power cord plug and socket for damage. A build-up of dust
could cause the tracking phenomenon and result in fire.
Periodically inspect the power cord for damage. Failure to discover damage could result in
electrical shock or fire.
Precautions when handling the circuit boards
Always follow these precautions when handling circuit boards in order to prevent static electricity from damaging them:
• Precautions when transporting and storing circuit boards
1. Place circuit boards in a conductive bag or case, or wrap them in aluminum foil.
2. Store them in a place not exposed to direct sunlight.
• Precautions when changing circuit boards
1. Always disconnect the power supply cord or cables before unplugging or plugging in any connectors.
2. Always handle the circuit board by its insulated parts so that you do not touch the terminals or soldered sections.
• Precautions when inspecting circuit boards
1. Before touching the circuit board, always touch the frame (or some other grounded item) to ground any static elec-
tricity in the body.
2. Never determine a defect on a circuit board by touching it with your hand or a metal object. Use a moving part (such
as a solenoid, motor, or lamp) for checking the circuit board.
