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

Main charger section
The main charging section consists of the main charger unit, drum, potential sensor and so on. The drum is electrically
charged uniformly by means of a grid to form a latent image on the surface.
The potential sensor (DPS) reads the drum surface potential and corrects surface potential.
The main charger unit has the main charger cleaning motor (CLM), main charger cleaning pad for automatic cleaning of
the charger wire.
The drum heater (DRH) inside the drum is turned on and off based on changes in ambient temperature and humidity to
stabilize the image quality.

(1) Original scanning
The original image is illuminated by the exposure lamp (EL) and scanned by the CCD in the CCD PWB (CCDPWB) via the
three mirrors and lens, the reflected light being converted to an electrical signal.
The mirror 1 and 2 frames travel to scan on the optical rails on the front and rear of the machine to scan from side to side.
The speed of the mirror 2 frame is half the speed of the mirror 1 frame.
When the DP is used, the mirror 1 and 2 frames stop at the DP original scanning position to start scanning the first side of
the original. The DP scans 2 sides of the original at the same time by using CIS to scan the second side of the original.

(1) Single component developing system
This machine uses the single component developing system, and reversal processing is performed with a + charged drum
(a-Si) and a + charged magnetic toner.
With the single component developing system, toner is electrically charged by friction with the developing sleeve and +
charged when it passes through the magnetic doctor blade.
The toner that has passed through the magnetic doctor blade forms a uniform layer on the developing sleeve.
When the toner layer comes to the location where the developing sleeve is the nearest to the drum, toner moves between
the drum and the developing sleeve by an electric field.
Then, when the developing sleeve passes through the nearest location to the drum, on the portion of the drum that has
been exposed to light, toner is attracted toward the drum by potential difference between the developing bias and the
drum surface and development is performed.
On the other hand, on the portion of the drum that has not been exposed to light, toner is attracted toward the sleeve and
development is not performed.
When toner comes to an area where the gap between the drum and the developing sleeve is large, an electric field disappears and toner does not leave the developing sleeve. Development is complete.

Transfer section
The transfer section comprises the transfer charger belt for transferring the toner image on the drum onto the paper, and
conveying the paper after transfer to the fuser section, the transfer roller for applying the transfer bias to the transfer
charger belt, etc.
When the paper passes between the drum and the transfer charger belt, the transfer bias current output from the transfer
high voltage PWB (THVPWB) is applied to the transfer roller.
This effects the transfer charging and the toner image developed on the drum is transferred to the paper.
Also, through the transfer charge, the transfer charger belt is charged and pulls the paper and separates it from the drum.

Cleaning section
The machine employs a blade cleaning method with a cleaning brush.
The cleaning section consists of the cleaning blade and cleaning brush which remove residual toner from the drum surface after transfer, the cleaning plate scraper that remove toner from the cleaning brush, and the cleaning spiral that carries the residual toner to the waste toner box.
The cleaning lamp (CL) consists of 18 LEDs and built into the main charger unit. The cleaning lamp (CL) removes residual
charge from the drum surface by exposing LED light to the drum.

Fuser section
The fuser section consists of the parts shown in the figure.
When the paper reaches the fuser section after the transfer process, it passes through the gap between the press roller
and heat roller, which is heated by fuser heaters M, S and L (FH-M, FH-S and FH-L).
where pressure is applied by the pressure springs so that toner on the paper is melted and fused onto the paper
When the fuser process is completed, the paper is separated from the heat roller and press roller by their separation claws
and is ejected out of the copier by the rotation of the fuser eject pulley and roller.
The cleaning felt in contact with the heat roller cleans the surface of the heat roller.
The lower cleaning roller in contact with the press roller cleans the surface of the press roller.

PTC section
The PTC section intends to reduce improperly charged toner by discharging on the toner developed onto the drum and to
improve copy performance by decreasing adhesiveness of the toner onto the drum.
This increases adhesiveness of the toner onto the copied paper and prevents various poor images after copying.
The PTC charger unit has the PTC cleaning motor (PCLM), PTC cleaning pad for automatic cleaning of the charger wire.
