This Product Uses Lead (Pb) Free Solder Printed Circuit Boards (PCBs).

Information regarding Lead-Free (PbF) solder:

Distinction of PbF PCB:

PCBs (manufactured) using lead free solder will have a mark following the PCB part numbers in a label on the PCB.

Caution:

Pb free solder has a higher melting point than standard solder; typically the melting point is 50 - 70 F (30 - 40 C) higher. Please use a soldering iron with temperature control and adjust it to 700 20 F (370 10 C). Exercise care while using higher temperature soldering irons, do not heat the PCB for too long to prevent solder splash or damage to the PCB. Pb free solder will tend to splash when heated too high (about 1100 F/600 C). ECO SOLDER M705 (available from Senju Metal Industry Co., Ltd.:

URL: http://www.senju-m.co.jp) is recommended when repairing PbF PCBs.

The contents of this Service Manual and the Specifications are subject to change

nstallation and Relocation Cautions

CAUTION

Do not place the machine near heaters or volatile, flammable, or combustible materials such as curtains that may catch fire.

Do not place the machine in a hot, humid, dusty or poorly ventilated environment. Prolonged exposure to these adverse conditions can cause fire or electric shocks.

Place the machine on a level and sturdy surface that can withstand. If tilted, the machine may tip-over and cause injuries.

When relocating the machine, remove the toner and/or developer, and pack the machin with proper packing materials for shipping.

When moving the machine, be sure to unplug the power cord from the outlet. If the machine is moved with the power cord attached, it can cause damage to the cord which could result in fire or electric shock.

ower and Ground Connection Cautions

WARNING

Ensure that the plug connection is free of dust. In a damp environment, a contaminated connector can draw a significant amount of current that can generate heat and eventually cause fire over an extended period of time.

Always use the power cord provided with your machine. When an extension power cord is required, always use a properly rated cord.

120 V/15 A or AC 220 - 240V/10 A If you use a cord with an unspecified current rating, the machine or plug may emit smok or become hot to the touch externally.

Do not attempt to rework, pull, bend, chafe or otherwise damage the power cord. Do no place a heavy object on the cord. A damaged cord can cause fire or electric shocks.

Page 7

Never touch a power cord with wet hands. Danger of electric shock exists.

If the power cord is broken or insulated wires are exposed, replace immediately with a specified cord onl Using a damaged cord can cause fire or electric shocks.

Stop operation immediately if your machine produces smoke, excessive heat, unusual noise, or smell, or if water is spilt onto the machine. These conditions can cause fire. Immediately switch Off and unplug the machine.

Do not disconnect or reconnect the machine while it is on. Disconnecting a live connector can deform the plug and cause fire.

When disconnecting the machine, grasp the plug instead of the cord. Forcibly pulling on a cord can damage it and cause fire or electric shock.

When the machine is not used over an extended period of time, switch it Off and unplug it. If an unused machine is left connected to a power source for a long period, degraded insulation can cause electric shocks, current leakage or fire.

Be sure to switch Off and unplug the machine before accessing the interior of the machine for cleaning, maintenance or fault clearance. Access to a live machines interior can cause electric shock.

Be sure to switch Off and unplug the machine before accessing the interior of the machine for accessing interface cables, maintenance or fault clearance. Access to a live machines interior can cause electric shock.

Once a month, unplug the machine and check the power cord for the following. If you notice any unusual condition.

The power cord is plugged firmly into the receptacle. The plug is not excessively heated, rusted, or bent. The plug and receptacle are free of dust. The cord is not cracked or frayed.

thers

The machine has a built-in circuit for protection against lightning-induced surge current. If lightning strikes in your neighborhood, switch Off the machine. Disconnect the telephone line cable first, then unplug the power cord from the machine and reconnect only when the lightning storm has stopped. If you notice flickering or distorted images or noises on your audio-visual units, your machine may be causing radio interference. Switch it Off and if the interference disappears, the machine is the cause of the radio interference. Perform the following procedure until the interference is corrected.

Move the machine and the TV and/or radio away from each other. Reposition or reorient the machine and the TV and/or radio. Unplug the machine, TV and/or radio, and replug them into outlets that operate on different circuits. Reorient the TV and/or radio antennas and cables until the interference stops. For an outdoor antenna, ask your local electrician for support. Use a coaxial cable antenna.

perating Safeguards

WARNING

Laser Handling Precautions

The optical laser system employed by this photocopier is completely sealed b a protective housing and an external cover. Therefore, the laser beam will no stray or leak during photocopying operation. However, when servicing the photocopier, take the following precautions:

1. Do not insert any screwdrivers or other tools that have high reflective properties into the laser's path.

2. Before servicing the photocopier, remove watches, rings, or other metallic objects that you may be wearing. (This is to avoid the danger of the lase striking the eye by reflecting off the metallic objects being worn.) Since the laser beam cannot be seen with the naked eye, for maximum safety, please follow the above precautions.

Safety Interlock Switches

- The service technician may defeat the safety interlock switches by inserting interlock cheater into the opening of the switch cover.

- Ensure to remove the interlock cheater from the switch cover after completio of service.

2.7.8. Firmware Emergency Recovery

The easiest method to recover the firmware in an Emergency Recovery routine is to either use the Local Firmware Update Tool software by selecting the Independent File method, or using the Master Firmware Flash Card method (2 Flash Cards required).

Whichever method you select, it is easier to restore the machine's firmware to the Standard (AAV) Type first as it only requires 2 files to bring the machine to initial working condition. (Install the files in this order: SC and SPC).

After recovering, if optional PCL or PS/PCL firmware is required, use the Network Firmware Update Tool or the Local Firmware Update Tool to update the firmware to the required level.

If the unit does not boot up properly, follow the steps below:

1. Turn the power Off (use the power switch on the right side of the unit).

- Before proceeding to the next step, you must prepare either the Local Firmware Update Tool or create the Master Firmware Flash Cards (read the appropriate sections first).

- If using the Master Firmware Card, insert the Master Firmware Flash Cards in the unit.

2. Turn the power On while holding the “ENERGY SAVER” key.

3. When the green lamp on the front panel turns On, release the “ENERGY SAVER” key.

- If using the Master Firmware Card, the unit will start updating the Firmware code files automatically.
