PRECAUTIONS BEFORE SERVICE When the user is using a word processor or personal computer from a wall outlet of the same line, take necessary steps to prevent the circuit breaker from opening due to overloads. Never disturb the LAN by breaking or making a network connection, altering termination, installing or removing networking hardware or software, or shutting down networked devices without the knowledge and express permission of the network administrator or the shop supervisor. HOW TO USE THIS BOOK DIS/REASSEMBLY, ADJUSTMENT To reassemble the product, reverse the order of disassembly unless otherwise specified. TROUBLESHOOTING If a component on a PWB or any other functional unit including a motor is defective, the text only instructs you to replace the whole PWB or functional unit and does not give troubleshooting procedures applicable within the defective unit.
All troubleshooting procedures contained herein assume that there are no breaks in the harnesses and cords and all connectors are plugged into the right positions. The procedures preclude possible malfunctions due to noise and other external causes. PRECAUTIONS FOR SERVICE Check the area surrounding the service site for any signs of damage, wear or need of repair. Keep all disassembled parts in good order and keep tools under control so that none will be lost or damaged. After completing a service job, perform a safety check. Make sure that all parts, wiring and screws are returned to their original positions. Do not pull out the toner hopper while the toner bottle is turning. This could result in a damaged motor or locking mechanism. If the product is to be run with the front door open, make sure that the toner hopper is in the locked position. Do not use an air gun or vacuum cleaner for cleaning the ATDC Sensor and other sensors, as they can cause electrostatic destruction. Use a blower brush and cloth. If a unit containing these sensors is to be cleaned, first remove the sensors from the unit.
PRECAUTIONS FOR DISASSEMBLY/REASSEMBLY 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. Before attempting to replace parts and unplug connectors, make sure that the power cord of the copier has been unplugged from the wall outlet. Be sure to use the Interlock Switch Actuating Jig whenever it is necessary to actuate the Interlock Switch with the covers left open or removed. While the product is energized, do not unplug or plug connectors into the circuit boards or harnesses. Never use flammable sprays near the copier. A used battery should be disposed of according to the local regulations and never be discarded casually or left unattended at the user's premises. When reassembling parts, make sure that the correct screws (size, type) and toothed washer are used in the correct places. 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.
PRECAUTIONS FOR CIRCUIT INSPECTION Never create a closed circuit across connector pins except those specified in the text and on the printed circuit. When creating a closed circuit and measuring a voltage across connector pins specified in the text, be sure to use the GND wire. HANDLING OF PWBS During Transportation/Storage: During transportation or when in storage, new P.W. Boards must not be indiscriminately removed from their protective conductive bags. Do not store or place P.W. Boards in a location exposed to direct sunlight and high temperature. When it becomes absolutely necessary to remove a Board from its conductive bag or case, always place it on its conductive mat in an area as free as possible from static electricity. Do not touch the pins of the ICs with your bare hands. Protect the PWBs from any external force so that they are not bent or damaged. During Inspection/Replacement: 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. Before unplugging connectors from the P.W. Boards, make sure that the power cord has been unplugged from the outlet.
When removing a Board from its conductive bag or conductive case, do not touch the pins of the ICs or the printed pattern. Place it in position by holding only the edges of the Board. When touching the PWB, wear a wrist strap and connect its cord to a securely grounded place whenever possible. If you cannot wear a wrist strap, touch a metal part to discharge static electricity before touching the PWB. Note that replacement of a PWB may call for readjustments or resetting of particular items. HANDLING OF OTHER PARTS The magnet roller generates a strong magnetic field. Do not bring it near a watch, floppy disk, magnetic card, or CRT tube.
HANDLING OF THE PC DRUM * Only for Products Not Employing an Imaging Cartridge. During Transportation/Storage: Use the specified carton whenever moving or storing the PC Drum. The storage temperature is in the range between -20°C and +40°C. In summer, avoid leaving the PC Drum in a car for a long time. Handling: Ensure that the correct PC Drum is used. Whenever the PC Drum has been removed from the copier, store it in its carton 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 oilbase solvent, fingerprints, and other foreign matter. Do not scratch the surface of the PC Drum. Do not apply chemicals to the surface of the PC Drum. Do not attempt to wipe clean the surface of the PC Drum.
If, however, the surface is contaminated with fingerprints, clean it using the following procedure.
1. Place the PC Drum into one half of its carton.
3. Soak a small amount of either ethyl alcohol or isopropyl alcohol into a clean, unused Dust-Free Cotton Pad which has been folded over into quarters. Now, wipe the surface of the PC Drum in one continuous movement from its rear edge to its front edge and off its surface one to two times.
*Never move the Pad back and forth.
2. Gently wipe the residual toner off the surface of the PC Drum with a dry, DustFree Cotton Pad. A.Turn the PC Drum so that the area of its surface on which the line of toner left by the Cleaning Blade is present is facing straight up. Wipe the surface in one continuous movement from the rear edge of the PC Drum to the front edge and off the surface of the PC Drum. B. Turn the PC Drum slightly and wipe the newly exposed surface area with a CLEAN face of the Dust-Free Cotton Pad. Repeat this procedure until the entire surface of the PC Drum has been thoroughly cleaned.
*At this time, always use a CLEAN face of the dry Dust-Free Cotton Pad until no toner is evident on the face of the Pad after wiping.
4. Using the SAME face of the Pad, repeat the procedure explained in the latter half of step 3 until the entire surface of the PC Drum has been wiped. Always OVERLAP the areas when wiping. Two complete turns of the PC Drum would be appropriate for cleaning.
NOTE: Even when the PC Drum is only locally dirtied, wipe the entire surface. Do not expose the PC Drum to direct sunlight. Clean it as quickly as possible even under interior illumination. If dirt remains after cleaning, repeat the entire procedure from the beginning one more time.
HANDLING OF THE IMAGING CARTRIDGE * Only for Products Employing an Imaging Cartridge. During Transportation/Storage: The storage temperature is in the range between -20°C and +40°C. In summer, avoid leaving the Imaging Cartridge in a car for a long time. Handling: Store the Imaging Cartridge in a place that is not exposed to direct sunlight. Precautionary Information on the PC Drum Inside the Imaging Cartridge: Use care not to contaminate the surface of the PC Drum with oilbase solvent, fingerprints, and other foreign matter. Do not scratch the surface of the PC Drum. Do not attempt to wipe clean the surface of the PC Drum.
