MX-M753N NOTE FOR SERVICING - i MX-M753N Service Manual NOTE FOR SERVICING 1. Precautions for servicing 1) When servicing, disconnect the power plug, the printer cable, the network cable, and the telephone line from the machine, except when performing the communication test, etc. It may cause an injury or an electric shock. 2) There is a high temperature area inside the machine. Use an extreme care when servicing. It may cause a burn. 3) There is a high voltage section inside the machine which may cause an electric shock. Be careful when servicing. 4) Do not disassemble the laser unit. Do not insert a reflective material such as a screwdriver in the laser beam path. It may damage eyes by reflection of laser beams. 5) When servicing with the machine operating, be careful not to squeeze you hands by the chain, the belt, the gear, and other driving sections. 6) Do not leave the machine with the cabinet disassembled. Do not allow any person other than a serviceman to touch inside the machine. It may cause an electric shock, a burn, or an injury. 7) When servicing, do not breathe toner, developer, and ink excessively. Do not get them in the eyes. If toner, developer, or ink enters your eyes, wash it away with water immediately, and consult a doctor if necessary. 8) The machine has got sharp edges inside. Be careful not to damage fingers when servicing. 9) Do not throw toner or a toner cartridge in a fire. Otherwise, toner may pop and burn you. 10) When replacing the lithium battery of the PWB, use a specified one only. If a battery of different specification is used, it may be broken, causing breakdown or malfunction of the machine. 11) When carrying a unit with PWB or electronic parts installed to it, be sure to put it in an anti-static-electricity bag. It may cause a breakdown or malfunctions. 12) When the machine is moved over a bump, hold the grip on the right side of the machine to lift and cross the bump over. This is because the casters may be broken for a big bump. 2. Warning for servicing 1) Be sure to connect the power cord only to a power outlet that meets the specified voltage and current requirements. Avoid complex wiring, which may lead to a fire or an electric shock. It may cause a fire or an electric shock. 2) If there is any abnormality such as a smoke or an abnormal smell, interrupt the job and disconnect the power plug. It may cause a fire or an electric shock. 3) Be sure to connect the grounding wire. If an electric leakage occurs without grounding, a fire or an electric shock may result. To protect the machine and the power unit from lightening, grounding must be made. 4) When connecting the grounding wire, never connect it to the following points. It may cause an explosion, a fire or an electric shock. • Gas tube • Lightning conductor • A water pipe or a water faucet, which is not recognized as a grounding object by the authorities. • Grounding wire for telephone line 5) Do not damage, break, or work the power cord. Do not put heavy objects on the power cable. Do not bend it forcibly or do not pull it extremely. It may cause a fire or an electric shock. 6) Keep the power cable away from a heat source. Do not insert the power plug with dust on it into a power outlet. It may cause a fire or an electric shock. 7) Do not put a receptacle with water in it or a metal piece which may drop inside the machine. It may cause a fire or an electric shock. 8) With wet or oily hands, do not touch the power plug, do not insert the telephone line jack, do not operate the machine, or do not perform servicing. It may cause an electric shock. 3. Note for installation site Do not install the machine at the following sites. 1) Place of high temperature, high humidity, low temperature, low humidity, place under an extreme change in temperature and humidity. Paper may get damp and form dews inside the machine, causing paper jam or copy dirt. For operating and storing conditions, refer to the specifications described later. 2) Place of much vibrations It may cause a breakdown. 3) Poorly ventilated place An electrostatic type copier will produce ozone inside it. The quantity of ozone produced is designed to a low level so as not to affect human bodies. However, continuous use of such a machine may produce a smell of ozone. Install the machine in a well ventilated place, and ventilate occasionally. CAUTION DOUBLE POLE/NEUTRAL FUSING (200V series only)

MX-M753N NOTE FOR SERVICING - ii 4) Place of direct sunlight. Plastic parts and ink may be deformed, discolored, or may undergo qualitative change. It may cause a breakdown or copy dirt. 5) Place which is full of organic gases such as ammonium The organic photo-conductor (OPC) drum used in the machine may undergo qualitative change due to organic gases such as ammonium. Installation of this machine near a diazo-type copier may result in dirt copy. 6) Place of much dust When dusts enter the machine, it may cause a breakdown or copy dirt. 7) Place near a wall Some machine require intake and exhaust of air. If intake and exhaust of air are not properly performed, copy dirt or a breakdown may be resulted. 8) Unstable or slant surface If the machine drops or fall down, it may cause an injury or a breakdown. If there are optional paper desk and the copier desk specified, it is recommendable to use them. When using the optional desk, be sure to fix the adjuster and lock the casters. 4. Note for handling PWB and electronic parts When handling the PWB and the electronic parts, be sure to observe the following precautions in order to prevent against damage by static electricity. 1) When in transit or storing, put the parts in an anti-static bag or an anti-static case and do not touch them with bare hands. 2) When and after removing the parts from an anti-static bag (case), use an earth band as shown below: • Put an earth band to your arm, and connect it to the machine. • When repairing or replacing an electronic part, perform the procedure on an anti-static mat. 17-23/32" (45cm) 11-13/16" (30cm) 11-13/16" (30cm)

MX-M753N NOTE FOR SERVICING - iii 5. Note for repairing/replacing the LSU When repairing or replacing, be sure to observe the following items. 1) When repairing or replacing the LSU, be sure to disconnect the power plug from the power outlet. 2) When repairing or replacing the LSU, follow the procedures described in this Service Manual. 3) When checking the operations after repairing the LSU, keep all the parts including the cover installed and perform the operation check. 4) Do not modify the LSU. 5) When visually checking the inside of the machine for the operation check, be careful not to allow laser beams to enter the eyes. If the above precaution is neglected or an undesignated work is performed, safety may not be assured. 6. Note for handling the drum unit, the transfer unit, the developing unit, and the fusing unit When handling the OPC drum unit, the transfer unit, and the developing unit, strictly observe the following items. If these items are neglected, a trouble may be generated in the copy and print image quality. (Drum unit) 1) Avoid working at a place with strong lights. 2) Do not expose the OPC drum to lights including interior lights for a long time. 3) When the OPC drum is removed from the machine, cover it with light blocking material. (When using paper, use about 10 sheets of paper to cover it.) 4) Be careful not to attach fingerprints, oil, grease, or other foreign material on the OPC drum surface. (Transfer unit) 1) Be careful not to attach fingerprints, oil, grease, or other foreign material on the transfer roller. (Developing unit) 1) Be careful not to attach fingerprints, oil, grease, or other foreign material on the developing unit. (Fusing unit) 1) Be careful not to put fingerprints, oil, grease, or other foreign material on the fusing roller and the external heating belt. 2) Do not leave the fusing roller in contact state for a long time. 7. Screw tightening torque The screws used in this machine are largely classified into three kinds. These kinds are classified according to the shape of the screw grooves and use positions. The table below shows the kinds of the screws and the tightening torques depending on the use position. When tightening the screws for repair or maintenance, refer to the table. However, for the other conditions of tightening screws than specified on this table, or when a special care is required, the details are described on the separate page. Refer to the descriptions on such a case. NOTE: Especially for the screw fixing positions where there is an electrode or a current flows, use enough care to tighten securely to avoid loosening.
