1.1 Before Starting Service1.1.1SafetyTo prevent any accident that may occur during maintenance service, any warning or any cau-tion regarding the service must be strictly observed. Do not perform any hazardous operation.

1. Power SupplyTo prevent electrical shocks, burns, or injury, etc., be sure to switch OFF the machine and disconnect the plug before starting the maintenance service. If the machine has to be switched ON, such as when measuring a voltage, take extra care to avoid an electrical shock.

2. Drive AreaNever inspect, clear or lubricate the drive components, such as chain belts, chain wheels or gears, when the machine is in operation.

3. Heavy PartsWhen removing or installing heavy parts, keep your back straight and lift with your legs. Some parts should not be lifted by one person:

IOT (Platen): 31.5kg (requires 3 persons)2 Tray Modules: 8.6kg (requires 2 persons)

Take extra care of your working posture to prevent backache.4. Safety Devices

See that safety devices for preventing accidents, such as fuses, circuit breakers, interlock switches, etc., and those for protecting customers from injury, such as panels and covers, function properly. Modifications that hinder the function of any safety devices are strictly prohibited.

5. Installing and Removing PartsThe edges of parts and covers may be sharp, so take care not to touch them. Be careful not to touch those parts, and wipe off any oil that may have adhered to your fingers or hands before servicing. When pulling out parts, cables, etc., do it gently. Do not use excessive force.

6. Specified ToolsFollow the instructions when a particular tool is specified.

7. Cleaning Up Toner SpillsSince toner can be explosive, sweep or brush any spilled toner into a container to collect it. To clean away the remaining toner using a vacuum cleaner, always use an FX standard vacuum cleaner that is toner-tolerant. Never use the customer's vacuum cleaner.

8. Earthquake Preparedness MeasuresIf the customer requests earthquake proofing, an earthquake preparedness kit is avail-able.Check the Service Guide for more information on the earthquake preparedness kit.

9. Modifications to the MachineBefore altering the machine, submit an irregular use license application.

10. Other Safety PrecautionsFollow the recommendations in WORKING PRACTICES FOR ENGINEERS issued by FXAP EH&S (Environmental Health and Safety).

Before starting to troubleshoot, always check the following items:

The voltage of the power supply (measure the voltage at the power outlet to see if it is within specification).

The power cord for damage, short circuits, open circuits, and wrong internal connections. The machine for proper grounding. The machine is not installed in a place with high temperature, high humidity, low tempera-

ture, low humidity, or a place with drastic changes in temperature. The machine is not installed near a water outlet, humidifier, heater or fire source, dusty

areas, or under the direct draft of an air conditioner. The machine is not installed in a place where volatile or flammable gas is generated. The machine is not installed in a place exposed to direct sunlight. The machine is installed in a well-ventilated place. The machine is installed on a stable level surface. The paper is within specification (standard paper is recommended). The machine for any improper handling. The Periodic Replacement Parts are replaced at the proper intervals.Safety Considerations Before servicing, always unplug the power cord unless required otherwise. When the

power is turned ON, never touch a current-carrying part unless required otherwise. Also, since current is carried in the LVPS power switch/inlet even when the power is turned OFF, never touch this area.

When turning the power ON to perform a check while the Interlock Switch or Security Switch is also turned ON and the covers are removed, always disconnect the connector ( P/J140) that is connected to the ROS, unless required otherwise, because a laser beam might be emitted from the ROS.

When connecting the connector ( P/J520) on the HVPS according to the instructions in the RAP, never touch the HVPS and high-voltage output parts.

When performing a high voltage output check using the Input Diagnostics or Output Diag-nostics in Diagnostic Mode, make sure that all covers are installed unless specified other-wise. Also, never touch any high voltage output section when performing the high voltage output check.

When operating the Drive Section using the Input Diagnostics or Output Diagnostics in Diagnostic Mode, make sure that all covers are installed unless specified otherwise. Also, never touch the Drive Section while operating it.

Be careful not to burn yourself when touching parts that can get very hot. When servicing, use a grounded wrist band to remove static electricity from your body.Things to Note When Using RAPs When troubleshooting using RAPs, prepare normally working parts such as the AIOC

PWB, LVPS, HVPS and Fuser in advance because they might be required to identify a failure. In addition, if the fault cannot be repaired, replace the "parts considered to be the cause" and related parts in sequence and check the operation.

When servicing, always disconnect the power cord unless required otherwise. When the power cord is connected, never touch any current-carrying part unless absolutely neces-sary.
