1. Installation Precautions

WARNING

• Do not use a power supply with a voltage other than that specified. Avoid multiple connections to one outlet: they may cause fire or electric shock. When using an extension cable, always check that

it is adequate for the rated current. .....................................................................................................

• Connect the ground wire to a suitable grounding point. Not grounding the copier may cause fire or electric shock. Connecting the earth wire to an object not approved for the purpose may cause explosion or electric shock. Never connect the ground cable to any of the following: gas pipes, lightning rods, ground cables for telephone lines and water pipes or faucets not approved by the proper

authorities. ..........................................................................................................................................

CAUTION:

• Do not place the copier on an infirm or angled surface: the copier may tip over, causing injury. .........

• Do not install the copier in a humid or dusty place. This may cause fire or electric shock. .................

• Do not install the copier near a radiator, heater, other heat source or near flammable material. This

may cause fire. ...................................................................................................................................

• Allow sufficient space around the copier to allow the ventilation grills to keep the machine as cool

as possible. Insufficient ventilation may cause heat buildup and poor copying performance. ............

• Always handle the machine by the correct locations when moving it. .................................................

• Always use anti-toppling and locking devices on copiers so equipped. Failure to do this may cause

the copier to move unexpectedly or topple, leading to injury. ..............................................................

• Avoid inhaling toner or developer excessively. Protect the eyes. If toner or developer is accidentally ingested, drink a lot of water to dilute it in the stomach and obtain medical attention immediately. If it gets into the eyes, rinse immediately with copious amounts of water and obtain medical atten-

tion. .....................................................................................................................................................

• Advice customers that they must always follow the safety warnings and precautions in the copier’s

instruction handbook. .........................................................................................................................

2. Precautions for Maintenance

WARNING

• Always remove the power plug from the wall outlet before starting machine disassembly. ................

• Always follow the procedures for maintenance described in the service manual and other related

brochures. ..........................................................................................................................................

• Under no circumstances attempt to bypass or disable safety features including safety mechanisms

and protective circuits. ........................................................................................................................

• Always use parts having the correct specifications. ............................................................................

• Always use the thermostat or thermal fuse specified in the service manual or other related brochure when replacing them. Using a piece of wire, for example, could lead to fire or other serious acci-

dent. ...................................................................................................................................................

• When the service manual or other serious brochure specifies a distance or gap for installation of a

part, always use the correct scale and measure carefully. ..................................................................

• Always check that the copier is correctly connected to an outlet with a ground connection. ...............

• Check that the power cable covering is free of damage. Check that the power plug is dust-free. If it

is dirty, clean it to remove the risk of fire or electric shock. .................................................................

• Never attempt to disassemble the optical unit in machines using lasers. Leaking laser light may

damage eyesight. ...............................................................................................................................

• Handle the charger sections with care. They are charged to high potentials and may cause electric

shock if handled improperly. ...............................................................................................................

CAUTION

• Wear safe clothing. If wearing loose clothing or accessories such as ties, make sure they are safely

secured so they will not be caught in rotating sections. ......................................................................

• Use utmost caution when working on a powered machine. Keep away from chains and belts. ..........

• Handle the fixing section with care to avoid burns as it can be extremely hot. ..................................

• Check that the fixing unit thermistor, heat and press rollers are clean. Dirt on them can cause

abnormally high temperatures. ...........................................................................................................

Page 9

• Do not remove the ozone filter, if any, from the copier except for routine replacement. ......................

• Do not pull on the AC power cord or connector wires on high-voltage components when removing

them; always hold the plug itself. ........................................................................................................

• Do not route the power cable where it may be stood on or trapped. If necessary, protect it with a

cable cover or other appropriate item. ................................................................................................

• Treat the ends of the wire carefully when installing a new charger wire to avoid electric leaks. ..........

• Remove toner completely from electronic components. .....................................................................

• Run wire harnesses carefully so that wires will not be trapped or damaged. ......................................

• After maintenance, always check that all the parts, screws, connectors and wires that were removed, have been refitted correctly. Special attention should be paid to any forgotten connector,

trapped wire and missing screws. .......................................................................................................

• Check that all the caution labels that should be present on the machine according to the instruction

handbook are clean and not peeling. Replace with new ones if necessary. .......................................

• Handle greases and solvents with care by following the instructions below: ......................................

· Use only a small amount of solvent at a time, being careful not to spill. Wipe spills off completely.

· Ventilate the room well while using grease or solvents.

· Allow applied solvents to evaporate completely before refitting the covers or turning the power switch on.

· Always wash hands afterwards.

• Never dispose of toner or toner bottles in fire. Toner may cause sparks when exposed directly to

fire in a furnace, etc. ...........................................................................................................................

• Should smoke be seen coming from the copier, remove the power plug from the wall outlet immedi-

ately. ...................................................................................................................................................

3. Miscellaneous

WARNING

• Never attempt to heat the drum or expose it to any organic solvents such as alcohol, other than the

specified refiner; it may generate toxic gas. ........................................................................................

1-5-1 Precautions for assembly and disassembly

(1) Precautions

Be sure to turn the power switch off and disconnect the power plug before starting disassembly. When handling PWBs, do not touch connectors with bare hands or damage the PWB. Do not touch any PWB containing ICs with bare hands or any object prone to static charge. When removing the hook of the connector, be sure to release the hook. Take care not to get the wire caught. To reassemble the parts, use the original screws. If the types and the sizes of screws are not known, refer to the PARTS LIST.

(2) Drum

Note the following when handling or storing the drum. When removing the drum unit, never expose the drum surface to strong direct light.

Keep the drum at an ambient temperature between 0 90% RH. Avoid abrupt changes in temperature and humidity. Avoid exposure to any substance which is harmful to or may affect the quality of the drum. Do not touch the drum surface with any object. Should it be touched by hands or stained with oil, clean it.

(4) How to tell a genuine Kyocera Mita toner container

As a means of brand protection, the Kyocera Mita toner container utilizes an optical security technology to enable visual validation. A validation viewer is required to accomplish this.

Hold the validation viewer over the left side part of the brand protection seal on the toner container. Through each window of the validation viewer, the left side part of the seal should be seen as follows:

A black-colored band when seen through the left side window A shiny or gold-colored band when seen through the right side window

The above will reveal that the toner container is a genuine Kyocera Mita branded toner container, otherwise, it is a counterfeit.

2-1-2 Drum section

(1) Drum section

The durable layer of organic photoconductor (OPC) is coated over the aluminum cylinder base. The OPC tend to reduce its own electrical conductance when exposed to light. After a cyclic process of charging, exposure, and development, the electrostatic image is constituted over the OPC layer. Since the OPC is materialized by resin, it is susceptible to damage caused by sharp edges such as a screwdriver, etc., resulting in a print quality problem. Also, finger prints can cause deterioration of the OPC layer, therefore, the drum (in the drum unit) must be handled with care. Substances like water, alcohol, organic solvent, etc., should be strictly avoided. As with all other OPC drums, the exposure to a strong light source for a prolonged period can cause a print quality problem. The limit is approximately 500 lux for less than five minutes. If the drum (drum unit) remains removed form the printer, it should be stored in a cool, dark place. .

As the drum rotates in a “clean (neutral)” state, its photoconductive layer is given a uniform, positive (+) corona charge dispersed by the main charger wire. Due to high-voltage scorotron charging, the charging wire can get contaminated by oxidization after a long run. Therefore, the charger wire must be cleaned at a specific interval. Cleaning the charging wire prevents print quality problems such as black streaks.

The charged surface of the drum is then scanned by the laser beam from the laser scanner unit. The laser beam (780 nm wavelength) beam is dispersed as the polygon motor revolves to reflect the laser beam over the drum. Various lenses and mirror are housed in the laser scanner unit, adjust the diameter of the laser beam, and focalize it at the drum surface.

2-1-4 Developing section

The latent image constituted on the drum is developed into a visible image. The developing roller contains a 3-pole (S-NS) magnet roller and an aluminum cylinder rotating around the magnet roller. Toner attracts to the magnet sleeve since it is powdery ink made of black resin bound to iron particles. Developing blade, magnetized by magnet, is positioned approximately 0.3 mm above the magnet sleeve to constitute a smooth layer of toner in accordance with the magnet sleeve revolution.

The developing roller is applied with the AC-weighted, positive DC power source. Toner on the magnet sleeve is given a positive charge. The positively charged toner is then attracted to the areas of the drum which was exposed to the laser light. (The gap between the drum and the magnet sleeve is approximately 0.32 mm.) The non-exposed areas of the drum repel the positively charged toner as these areas maintain the positive charge. The developing roller is also AC-biased to ensure contrast in yielding by compensating the toner’s attraction and repelling action during development.
