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 attention. .....................................................................................................................................................
• 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 accident. ...................................................................................................................................................
• 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. ...........................................................................................................
• 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 immediately. ...................................................................................................................................................
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. ........................................................................................
• Keep the machine away from flammable liquids, gases, and aerosols. A fire or an electric shock
might occur. ........................................................................................................................................

1-5-1 Precautions for assembly and disassembly
(1) Precautions
Before starting disassembly, press the Power key on the operation panel to off. Make sure that the Power
lamp is off before turning off the main power switch. And then unplug the power cable from the wall outlet.
When the fax kit is installed, be sure to disconnect the modular code before starting disassembly.
When handling PWBs (printed wiring boards), do not touch parts with bare hands.
The PWBs are susceptible to static charge.
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 cables 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 -20°C/-4°F and 40°C/104°F and at a relative humidity not
higher than 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.
(3) Toner
Store the toner container in a cool, dark place.
Avoid direct light and high humidity.

(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 Mechanical Construction
2-1-1 Paper feed/conveying section
Paper feed/conveying section consists of the paper feed unit that feeds paper from the cassette and the MP
tray paper feed unit that feeds paper from the MP tray, and the paper conveying section that conveys the fed
paper to the transfer/separation section.
(1) Cassette paper feed section
Paper cassette is the universal type that is applicable to various paper sizes by adjusting the side guides and
paper stopper and approximate 500 pages can be put in. Mechanism in the paper cassette consists of the bottom plate that lifts the paper in order to let it touch the pickup roller and the retard roller that prevents papers
from multiple feeding. Paper that is drawn out by the rotation of pickup roller of the cassette paper feed section is then sent in between the feed roller and the retard roller. Function of the built-in torque limiter in the
retard roller gives weak resistance force against the rotation. Normally, when only a page is drawn out by the
rotation of pickup roller, the paper is conveyed to the machine by the rotation of feed roller on its own. If the
pickup roller drew out two lapped pages someway, the upper paper is conveyed by the feed roller and the
lower paper stays due to the rotation resistant force of the retard roller because the friction force between
papers is smaller than the rotation resistance force of the retard roller and then the multiple paper feed can be
prevented.

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.

2-1-5 Transfer/Separation section
The image developed by toner on the drum is transferred onto the paper because of the electrical attraction
between the toner itself and the transfer roller. The transfer roller is negatively biased so that the positively
charged toner is attracted onto the paper while it is pinched by the drum and the transfer roller.

2-1-6 Cleaning section
After the transferring process, the drum needs to be physically cleaned of toner which is residual after the
development process. The cleaning blade is constantly pressed against the drum and scrapes the residual
toner off to the cleaning roller. The waste toner is collected at the output end of the sweep roller and sent to
the waste toner box.
After the drum is physically cleaned, it then must be cleaned to the electrically neutral state. This is necessary
to erase any residual positive charge, ready to accept the uniform charge for the next print process. The residual charge is canceled by exposing the drum to the light emitted from the cleaning lamp (CL). This lowers the
electrical conductivity of the drum surface making the residual charge on the drum surface escape to the
ground.

2-1-7 Fuser section
The toner on the paper is molten and pressed into the paper as it passes between the heat roller and the
press roller in the fuser unit.
The heat roller has a fuser heater (FH) inside which continuously turns on and off by the fuser thermistor
(FTH) to maintain the constant temperature onto the heat roller surface.
Should the temperature of the heat roller exceed the predetermined value, the fuser thermostat (FTS) is activated to effectively disconnect the fuser heater (FH) from power.
Fuser temperature is optimized to the paper type. The heat roller is resin coated by florin to prevent toner from
accumulating on the roller after a long run. Care must be taken while handling the heat roller not to scratch the
roller surface as doing so may result in print problems. The heat roller has four separators (claws) which are
continuously in contact with its surface. These separators (claws) prevent the paper on which toner has been
fused from being wound around the heat roller causing paper jam.
The press roller is made of the heat-resistant silicone rubber. This roller is used to strongly press the paper
towards the heat roller by means of press springs.

(4) Firmware Environment Commands
The printer maintains a number of printing parameters in its memory. There parameters may be changed permanently with the FRPO (Firmware RePrOgram) commands.
This section provides information on how to use the FRPO command and its parameters using examples.
Using FRPO Commands for Reprogramming Firmware
The current settings of the FRPO parameters are listed as optional values on the service status page.
Note: Before changing any FRPO parameter, print out a service status page, so you will know the parameter
values before the changes are made. To return FRPO parameters to their factory default values, send the
FRPO INIT (FRPO-INITialize) command.(!R! FRPO INIT; EXIT;)
The FRPO command is sent to the printer in the following sequence:
!R! FRPO parameter, value; EXIT;
Example: Changing emulation mode to PC-PR201/65A
!R! FRPO P1, 11; EXIT;
