For the Utmost safety

For replacement parts, use the genuine parts with their part numbers specified in the parts manual. Use

of a wrong part could cause an overload or dielectric breakdown resulting in an electric shock or fire.

Replace a blown fuse or thermal fuse with the corresponding genuine part with its part number specified in the parts manual. Use of a fuse with a different rating or one with the same rating but of a type can result in a fire. Especially when a thermal fuse blows frequently, the thermal control system is probably faulty. Be sure to take necessary action.

Before attempting to disassemble the machine, be sure to unplug its power cord. The machine contains a hlgh voltage unif and a circuit with a large current capacity that may cause an electric shock or burn from sparking. The machine also contains quick moving parts, which could injure a person. If the machine uses a laser, a person can lose his/her eyesight by a laser beam leak.

Wherever feasible, keep the covers and parts mounted when energizing the machine. If it is absolutely necessary to energize the machine with its cover removed, do not touch an exposed part that is being charged and use care not to allow your clothing to be caught by a timing belt, gear, or other moving part.

Do not leave the machine unattended while it is being energized,

! Warning

differeni

! Caution

To actuate an interlock switch with a cover removed or opened, be sure to use the interlock switch actuating jig. Use of folded paper can damage the interlock switch mechanism.

Page 3

! Caution

A high voltage is being applied to the part marked with the symbol shown on the right. Touching it can cause an electric shock. Be sure to unplug the power cord when servicing this part or other parts near it.

When the machine is energized with any of its covers removed, never use a flammable spray near it, as a fire can result,

Make sure that correct screws (diameter and length of the screw, binding/tapping screws) are used in the correct places when assembling parts. If a wrong screw is used, a short insulating distance could result. It could also result in collapsed threads, which provides only a poor grounding connection, resulting in an, electric shock,

A toothed washer and spring washer, if used originally, must be reinstalled. If they are left out, a contact failure results causing an electric shock or fire,

Replace a lithium cell only with one having the part number specified in the parts manual. An explosion could result if the cell is installed with wrong polarity or a wrong cell is installed. Dispose of a used lithium cell according to the applicable local regulations. Never throw it away or abandon it on the users premises.

Other Precautions

While the machine is being energized, do not unplug or plug in a connector on a PWB or relay harness.

Since the Magnet Roller of the Imaging Unit generates a strong magneticforce, do not bring a CRT, watch,

floppy disk, or magnetic card near it.

Use of an air gun parts to break down. Be sure therefore to use a blower brush or cloth to clean these parts. If a unit is to be cleaned, be sure to remove the sensors in advance.

l-l. PRECAUTIONS FOR DISASSEMBLY/ADJUSTMENTS

Observe the following precautions whenever servicing the copier.

Be sure to unplug the copier from the outlet before attempting to service the copier.

The basic rule is not to operate the copier anytime during disassembly. If it is absolutely necessary to run the copier with its covers removed, use care not to allow your clothing to be caught in revolving parts such as the timing belt and gears.

Be sure to use the Interlock Switch Actuating Jig whenever it is necessary to aotuate the Interlock Switch

with the covers left open or removed,

Do not plug in or unplug print jacks on the Board or connect or disconnect the Board connectors while

power is being supplied to the copier.

Do not use flammable spray around the copier in operation.

The Magnet Roller of the Imaging Unit generates strong magnetioforce. Do not bring it nearacathode-ray

A toothed washer is used with the screw that secures the ground wire to ensure positive conduction. Do

not forget to insert this washer at reassembly.

To reassemble the copier, reverse the order of disassembly unless otherwise specified.

If it becomes necessary to replace the thermal fuse or any other fuse mounted on a board, be sure to use

one of the rating marked on the blown fuse. Always note the rating marked on the fuse, as the rating and mounting site or number used are subject to change without notice.

During Inspection:

Avoid checking the IC directly with a multimeter; use connectors on the Board.

Never create a closed circuit across IC pins with a metal tool.

Handling:

Ensure that the correct PC Drum is used.

Wheneverthe PC Drum has been removed from the copier, store it in its container or protect it with a Drum

Cloth.

The PC Drum exhibits greatest light fatigue after being exposed to strong light over an extended period

of time. Never, therefore, expose it to direct sunlight.

Use care not to contaminate the surface of the PC Drum with oil-base solvent, fingerprints, and other for-

eign matter.

Purpose of Application of Red Paint

Red paint is applied to the screws which cannot be readjusted, set, or reinstalled in the field. The basic rule is not to remove or loosen the screws to which red paint is applied. In addition, be advised that, if two or more screws are designated as those which must not be touched on a single pat-t, only one representative screw may be marked with red paint.
