NOTE FOR SERVICING
This Service Manual uses some photographs to assure safe operation. Please understand the meanings of photographs before servicing. WARNING: If this WARNING should be ignored, a serious danger to life or a serious injury may result. CAUTION: If this CAUTION should be ignored, injury or damage to property could result.
2. 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 extreme care when servicing. 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 the machine while operating, be careful not to make contact with chains, belts, gear, and any other moving parts. 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 you 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 on the PWB, use only the specified battery. If a battery of different specification is used, it may not be compatible and cause breakdown or malfunction of the machine. 11) When carrying an electric unit or a PWB, use an anti-static (electricity) bag. Failure to do so may cause component failure or machine malfunction.
1. 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. 2) If there is any abnormality such as 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 the machine is properly grounded. Failure to ground the machine properly may result in an electric shock or fire. To protect the machine and the power unit from lightening, grounding must be made. 4) When connecting the ground wire, never connect it to the following points as it may cause an explosion, 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 stress the power cord. Do not put heavy objects on the power cord. Do not bend or pull the cord forcefully. It may cause a fire or 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) Do not touch the power plug, insert a telephone jack, perform service or operate the machine with wet or oil hands. It may cause an electric shock.
3. 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.

3. Developer/Drum life end definition
When the developer/drum counter reaches the specified level. When the developer/drum rpm reaches the specified level. When either of the above reached the specified level, it is judged as life end. In an actual case, when correction or warm-up operation is performed as well as output operation, the developer and the drum rotates. Therefore, the developer/drum consuming level cannot be determined only by the copy/print quantity. When, therefore, the rpm reaches the specified level, it is judged as life end. To check the drum and developer life, use SIM22-1. Developer/drum counter Developer/drum 26cpm model 75K 31cpm model 100K Number of rotations (Rotations) 550K

(2) MG roller main pole position adjustment
1) Put the developing unit on a flat surface. 2) Tie a needle or pin on a string. 3) Hold the string and bring the needle close to the MG roller horizontally. (Do not use paper clip, which is too heavy to make a correct adjustment.) (Put the developing unit horizontally for this adjustment.) 4) Do not bring the needle into contact with the MG roller, but bring it to a position 2 or 3mm apart from the MG roller. Mark the point on the MG roller which is on the extension line from the needle tip. 5) Measure the distance from the marking position to the top of the doctor plate of the developing unit to insure that it is 9.1mm. If the distance is not within the specified range, loosen the fixing screw A of the main pole adjustment plate, and move the adjustment plate in the arrow direction to adjust.
