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. ........................................................................................................

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 imme-

diately. ............................................................................................................................................

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. .....................................................................................

Note: Values (hexadecimal) within [ ] indicate paper misfeed locations.

Reference 1: Widthwise A4 size and lengthwise A5 are identical in length, however, the fuser temperature differs. Detecting the fuser temperature depending on this temperature difference allows detection of paper misfeed due to a wrong paper size.

Reference 2: The DU cover of the duplex paper conveying section is designed to operate as being held against the main unit as the paper cassette is installed. (Paper feeding fails when the paper cassette is not properly installed because of the resultant space between the DU cover and the main unit.) Therefore, paper jam occurs if the paper cassette is opened in the middle of duplex printing.

Setting the paper feed operation (printer driver priority mode)

>>Paper Feed

Description

With printer driver priority mode, when selecting the specific paper feed location (a cassette or MP tray) with the printer driver (it is not automatic selection), paper is fed from the selected location. Message "Add Paper" is displayed when there is no paper in that location. When selecting the MP tray as the paper feed location, paper is fed with the timing of maximum size (A4). As for the setting media type (setting the paper type), setting of the printer driver is notified to the engine PWB. Duplex printing operation is still the ordinary operation, and paper jam occurs if paper size is different from the setting of the printer.

Purpose

To set the printer driver priority mode which priority is given to the setup of a printer driver when the ordinary paper feed operation mode is not suitable for the usage condition of the user.

Method

1. Enter the service mode [>>Paper feed].

2. Press the OK key. Message [Paper feed?] will be displayed.

3. Select the mode (Special? or Normal?) pressing the T key or S key.

Service items Description

Initializing the developer unit (toner install mode)

>>Developer

>>DRUM-CTRL

Description

The new developer unit is shipped from the factory with no toner contained. The developer can be automatically replete with toner when a toner container is installed onto it and the printer is turned on. However, because the toner reservoir in the developer has a large capacity, it requires a lengthy period of time until a substantial amount of toner has been fed to get the printer ready. (A new developer needs approximately 200 g for triggering the sensor inside.)

Purpose

To execute when the developer unit has been replaced.

Method

1. Enter the service mode [>>Developer].

2. Press the OK key. [>>Developer?] will be displayed.

3. Press the OK key. [Ready] will be displayed.

4. Turn off and on the printer. [Self test] [Please wait (Adding toner)] will displayed. The printer continually engages in this mode for a period of approximately 10 minutes, after which the printer reverts to the [Ready] state. [Ready] will displayed. Developer initialization is finished.

Completion

Automatic drum surface refreshing Description

The drum surface refreshing operation is normally performed when the power is turned on to the printer or during warm-up when the printer is recovering from the Sleep mode, but even then only at those times that the temperature/humidity sensor detects the drum surface to be in a state of dew condensation. By using this mode, it is possible to force the drum surface refreshing operation to be performed automatically at a predetermined period of time, regardless of the status detected by the temperature/humidity sensor.

Purpose

To prevent bleeding of the output image when the printer's operating environment is one of high humidity.

Method

1. Enter the service mode [>>DRUM-CTRL].

2. Press the OK key. [>>DRUM-CTRL?] will be displayed.

3. Press the OK key.

4. Press the T key or S key and select the desire mode (from 00 to 02).

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. Use only the specified parts to replace the fuser unit thermostat. Never substitute electric wires, as the printer may be seriously damaged. When removing the hook of the connector, be sure to release the hook.

(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.

(3) Toner container

Store the toner container(s) in a cool, dark place. Avoid direct light and high humidity.
