PREVENTIONOFPHYSICALINJURY

Before disassembling or assembling parts of the copier and peripherals, makesure thatthe copierpower cordis unplugged.

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

Note that some components ofthe copier and the paper tray unit aresupplied with electrical voltage even if the main power switch is turned off.

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

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 awayfrom the mechanical and the electrical components as the copier startsmaking copies as soon as the warm-up period is completed.

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

HEALTHSAFETYCONDITIONS

Never operate the copier without the ozone filters installed.

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

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

OBSERVANCEOFELECTRICALSAFETYSTANDARDS

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

The NVRAM on the system control board hasa lithium battery which can explode if replaced incorrectly. Replace the NVRAM onlywith an identical one. The manufacturer recommends replacing the entire NVRAM. Do not recharge orburn this battery. Used NVRAM must be handled in accordancewith local regulations.

SAFETYANDECOLOGICALNOTESFORDISPOSAL

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

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

Dispose of replaced parts in accordance with local regulations.

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.

LASERSAFETY

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

If the place of installation is air-conditioned or heated, do not place the machine where it will be:
1. Subjected to sudden temperature changes
2. Directly exposed to cool air from an air-conditioner
3. Directly exposed to heat from a heater

Do not place the machine where itwill be exposed to corrosive gases.

Do not install the machine at any location over 2,000 m (6,500 feet) above sea level.

Place the copier on a strong and level base with the front and back of the machinewithin±5mm(0.2″)oflevel.

Do not place the machine where itmay be subjected to strong vibrations.

Do not connect the machine to a power source shared with another electrical appliance.

The machine can generate an electromagnetic field which could interfere with radio or television reception.

NOTE:If youcannot move thedevelopment unit platebehind the horizontal pin, turnthe front gear ofthe unit to the leftand try again.

Make sure the pipeline shutter is rotated down to the open position.

Reattachallremovedparts.

InitializingtheDrumSettings(B064Series)

Afterswitching on the machine, youmust execute SP2963 (Installation Mode) within 60 seconds to 1) Initialize the developer and force toner supply to the development unit, and 2) Initialize the auto process control settings.

SP2963 must beexecuted before sample copying or test printing.
If you do not press “Execute” in Step 2 in the following procedure within 60 seconds after the machine is switched on, the auto process control features (potentialsensorcalibration, Vsg,Vref,etc.) willnot initializecorrectly.
If the machine starts the auto process control routine before you have a chance to press Execute, switch the machine off and try again.

Connect the power cord.

Within one minute, before the auto process control settings initialize, execute SP2963.

PressClearModes �.
Ontheoperationpanelkeypad,pressC)�(!).
Hold downClear/Stope>formorethan3 seconds.
Press “Copy SP” on the touch-panel.

•Press0(!)(9C).

PressEnter®.
Enter the Developer Lot No. with the key display, then press “Execute”.

About four minutes is required to initialize toner supply and the auto process control settings.

Press “Exit” to leave the SP mode.

Attachtheappropriatedecals(provided)tothepapertrays.

Check copy quality and machine operation.

NOTE:At installation, use SP2963 to enter the lot number, initialize the developer,andtoforcetonersupplytothetonerhopper.Afterreplacing developer ina machine that has already been installed, do not use SP2963; execute SP2801 (TD Sensor Initial Setting) instead toenterthelotnumberandinitializetheTDsensor.(..-3.7.1)

InitializingtheDrumSettings(B140/B246Series)

You must do SP2963(Installation Mode) to 1) Initialize the developer and do a forced toner supply to the development unit, and 2) Initialize the auto process control settings.

Youmust open the front door before you switch the machine on. If you do this,the machine does not do the short automatic process control procedure, which is usually done after the machine power is turned on.
SP2963 must be done before you do sample copying or test printing.
If you do not press “Execute” in Step 6,the auto process control items (potential sensorcalibration,Vsg,Vref,etc.)will notinitializecorrectly.

Openthefrontdoor.

Connect the power cord.

Turn the main power switch on.

Go into the SP mode. (Push [Clear Modes], then enter “107”, then press and holddown [Clear/Stop]for atleast3 sec.)

Closethefrontdoor.

Do SP2963, enter the developer lot number with the key pad display, then push [Execute].

Approximatelyfour minutes is necessarytoinitialize toner supply and the auto process control settings.

Press“Exit” togooutoftheSPmode.

Attachthe applicable decals(supplied with themachine) to thepaper trays.

Check the copy quality and machine operation.

Important

At installation, use SP2963 to enter the lot number, initialize the developer, andto forcetoner supplyto thetoner hopper.
After you replace developer in a machine that has been already installed, do not use SP2963; use SP2801 (TD Sensor Initial Setting) instead to enter the lotnumberandinitializetheTDsensor.(..-3.7.1)

Exit the User Tools mode. Specify the number of copies, touch the center stapling symbol on the operation panel, then start the print job.

AuxiliaryTrays

The auxiliary trays are stored in the auxiliary tray storage pocket mounted on the backcover ofthe finisher.

Make sure that the customer understands the following points about these auxiliary trays:

The trailing edges of excessively curled or Z-folded paper can activate the trayfull sensors before the trayis actually full.
Once the “Exit Tray Full“ message displays, the job cannot continue until some sheets are removed from the tray whichis only partially full. The trays are designedto preventthis problem.
Theauxiliary trayfor theshift trayshould beinstalled forZ-folding jobs.
The auxiliary tray for the proof tray should be installed only when excessively curledpaperis triggeringearly”Exit TrayFull” alerts.
Normally, both auxiliary trays should be placed in the pocket mounted on the back of the finisher.

ProofExitAuxiliaryTray

Followthe procedures below to install the auxiliary trayfor the proof tray.

First, remove the paper form the paper feed tray, turn it upside down, and continue printing. This may solve the problem.
