!IMPORTANT SAFETY NOTICES

PREVENTION OF PHYSICAL INJURY

1.Before disassembling or assembling parts of the copier and peripherals, make sure that the copier power cord is unplugged.

2.The wall outlet should be near the copier and easily accessible.

3.Note that some components of the copier and the paper tray unit are supplied with electrical voltage even if the main power switch is turned off.

4.If any adjustment or operation check has to be made with exterior covers off or open while the main switch is turned on, keep hands away from electrified or mechanically driven components.

5.If the Start key is pressed before the copier completes the warm-up period (the Start key starts blinking red and green alternatively), keep hands away from the mechanical and the electrical components as the copier starts making copies as soon as the warm-up period is completed.

6.The inside and the metal parts of the fusing unit become extremely hot while the copier is operating. Be careful to avoid touching those components with your bare hands.

HEALTH SAFETY CONDITIONS

1.Never operate the copier without the ozone filters installed.

2.Always replace the ozone filters with the specified ones at the specified intervals.

3.Toner and developer are non-toxic, but if you get either of them in your eyes by accident, it may cause temporary eye discomfort. Try to remove with eye drops or flush with water as first aid. If unsuccessful, get medical attention.

OBSERVANCE OF ELECTRICAL SAFETY STANDARDS

1.The copier and its peripherals must be installed and maintained by a customer service representative who has completed the training course on those models.

2.The NVRAM on the system control board has a lithium battery which can explode if replaced incorrectly. Replace the NVRAM only with an identical one. The manufacturer recommends replacing the entire NVRAM. Do not recharge or burn this battery. Used NVRAM must be handled in accordance with local regulations.

1

1.SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL

Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly when exposed to an open flame.

2.Dispose of used toner, developer, and organic photoconductors in accordance with local regulations. (These are non-toxic supplies.)

3.Dispose of replaced parts in accordance with local regulations.

4.When keeping used lithium batteries in order to dispose of them later, do not put more than 100 batteries per sealed box. Storing larger numbers or not sealing them apart may lead to chemical reactions and heat build-up.

LASER SAFETY

The Center for Devices and Radiological Health (CDRH) prohibits the repair of laser-based optical units in the field. The optical housing unit can only be repaired in a factory or at a location with the requisite equipment. The laser subsystem is replaceable in the field by a qualified Customer Engineer. The laser chassis is not repairable in the field. Customer engineers are therefore directed to return all chassis and laser subsystems to the factory or service depot when replacement of the optical subsystem is required.

!WARNING

Use of controls, or adjustment, or performance of procedures other than those specified in this manual may result in hazardous radiation exposure.

!WARNING

WARNING: Turn off the main switch before attempting any of the procedures in the Laser Unit section. Laser beams can seriously damage your eyes.

Scanning	Overview	• The number of exposure lamp is one. (A229: 2	2-13
		lamps)
		• The CCD is changed to 4-channel type because
		of a higher processing speed. (A229: 2 channels)
		• A reflector is added to 1st scanner.
		• The Scanner Motor has been changed to a DC
		Servo type because of a higher processing
		speed.
		• The location of Lamp Regulator moves onto the
		1st scanner.
Laser	Overview	• The LD unit and Polygon Motor have been	N/A
Exposure		changed because of a higher processing speed.
		• The method controlling the LD has been changed

Process	Image Density	The toner amount in the development unit is	2-36
Control	Control	updated using Vsp/Vsg data in addition to the Vref
		update.
Drum Unit	Drum Flange	The holes for airflow have been added to Drum	2-47
		Flange to make cooling power up because of higher
		processing speed.
Drum Unit	Rotation Speed	362 mm/s (A229: 330 mm/s)	N/A
		This is because a higher copying speed.
	Corona Wire	One of the conditions making the cleaner start	2-43

		changed to the counter direction to increase the
		cleaning ability.
		• The brush has been changed from a rope type to
		a straight type. A rope type scrapes off the drum
		surface too much because of the change of the

Transfer	Transfer Belt	The surface treatment has been changed to		N/A
		increase cleaning ability.
	Cleaning Bias	The nylon tube has been added as the surface of		N/A
	Roller	the cleaning bias roller to increase the cleaning
		ability.
		This allows to increasing the maximum charging
		voltage up to 1000 V (A229: 330 V).
	Bushing	A bearing has been added to the bushing to make		N/A
		the movement smoother.
	Gear	The gear has been changed to a diagonal type with		2-58

		type to increase reliability.
	Paper size setting	The paper size setting can be done at the front side		2-72

Paper	Inverter Exit	The Inverter Exit Clutch has been added to stop a		N/A
Exit/Duplex	Clutch	paper coming into the duplex unit for a while.
		This is to keep the maximum productivity of printing
		even when it takes a longer time for image

Electrical	BICU Board	• Scanner control circuit has been independent	N/A
Compo-		from SBICU as MCU (Motor Control Unit) and
nents		Scanner Motor Drive Board is deleted.
		The name of SBICU is changed to BICU.
		This is because the Scanner Motor has been
		changed from a stepper motor to a servomotor to
		enable the copying speed in the ADF 1 to 1 mode
		to be 70 cpm.
		• The exposure lamp, APS sensor and scanner HP
		sensor are also connected to the MCU.
	I/O Board	The RDS function has been independent from	N/A
		the I/O board as RDS Board and has been
		controlled by the BICU board because of the
		following reasons:
		1. The I/O board can completely turn off in the
		weekly timer off mode.
		2. It has been possible that only the RDS board is
		replaced.
	PSU	A 38V output has been added for the scanner motor	N/A
		that is changed from a stepper motor to a servo-
		motor.
	CNB	This is a new name of the Interface Board	N/A
	(Connector	which the functions for the registration motor,
	Board)	by-pass motor and development motor are
		deleted from.
		Those functions are on the DRB (Driver Board) as a
		new board.
		This is to reduce the harnesses used.
	12V Power	The DC/DC converter has been deleted and its	N/A
	Supply Board	function has moved to the PSU.
	DRB	This is an interface board for the signal lines of	N/A
	(Driver Board)	the registration motor, by-pass motor and
		development motor.
		The power line for each motor is connected to the
		CNB.
	Copy Connect	The connection between the BICU and Copy	N/A
	Board	Connect Board has been changed from via the FCC
		cable to via the interface board.
		This is to make installation easier.
	Printer Controller	The connection between the BICU and Printer	N/A
		Controller has been changed from only via the
		FCC cable to via the interface board and the
		FCC cable.
		This is to make installation easier.

Installation	Finisher	• The caps on the upper left cover of the copier	3-22
Procedure	(B302, B312)	have not been equipped, so that it is not	3-29
		necessary to remove them when a finisher is
		installed.
		• New type of grounding bracket.
Installation	Output Tray	• A cavity has been made in each Paper Exit Roller
Procedure		and a plug is prepared beside each roller on the
		shaft. The plugs are necessary to be inserted into
		the cavities.
		• The caps on the upper left cover have become
		accessories of the Output Tray and are
		necessary to be installed.
		• The stack height sensors at the paper exit area
		have become accessories of the Output Tray and
		are necessary to be installed.
