Chapter 1 Service Call Procedure

1.1 Before Starting the Servicing

1.1.1 Safety

To prevent any accident that may occur during maintenance servicing, any WARNING or CAUTION regarding the servicing must be strictly observed. Do not perform any hazardous operation.

1. Power Supply

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

2. Drive Area

Never inspect or lubricate the drive area such as the gears during the machine operation.

3. Heavy Parts

The weight of the machine is 20kg. When moving the machine to ensure sufficient working space, take extra care to prevent back pain.

4. Safety Device

See that safety devices for preventing mechanical 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 the parts

The edge of parts and covers may be sharp, take care not to touch them. If the oil gets onto your hand, wipe it off before getting on with the servicing. When removing parts or cables, do not pull them out by force but remove them slowly.

6. Specified Tools

Follow the instruction when a tool is specified.

7. Organic Solvents

When using an organic solvent such as the Drum Cleaner or Machine Cleaner, pay attention to the following: Ensure good ventilation in the room to prevent too mu ch int ak e of th e so lvent. Do not use heated solvent. Keep away from fire.

8. Cleaning the Toner and Developer

As the toner may cause a dust explosion, sweep the spilt toner into a waste container. When using a cleaner to clean the remaining toner, be sure to use the FX standard toner -proof clea ner and not a customer's cleaner. Also, as the developer also contains toner, exercise the same caution during cleaning.

1-2

9. Modifications

If any modifications are deemed necessary for the printer, submit an Application for Approval of Modification prior to performing any work.

Chapter 1 Service Call Procedure

1.1 Before Starting the Servicing

10. Other Safety Precautions

For safety, you should also pay attention to precautions other than the above 1 to 9 items. Follow the SAFE WORKING PRACTICES FOR ENGINEERS issued by FXAP EH and S (Environmental Health and Safety) to ensure greater safety during servicing,

1.1.2 Other Things to Note

Pay attention to the following when performing maintenance service to avoid wrong or redundant servicing:

1. Reference Materials

Before performing maintenance servicing, read all relevant technical materials such as SB, FTI, or FTO for a systematic approach.

2. Disassembling

Make sure to check the assembled condition before removing parts or disassembling the machine.

3. Installation/Adjustment

After the installation or adjustment is complete, check that no parts or tools are left inside or on the assemblies before using the machine.

4. Handling of parts/consumables replaced

Make sure that the replaced parts or consumables as well as the packaging materials are collected back to the Service Center.

NOTE

If you have replaced the following consumables, affix the "U" sticker for the recyclable parts to be handled appropriately. Drum/toner cartridge (EP Cartridge) For recyclable parts, fill the necessary items in the "U-TAG" and perform collection.

5. General precautions

Take care not to disturb the customer's daily work. Place the drip cloth or paper on the customer's floor during work in the machine because color toners may dirty the floor and are difficult to clean. Throw any trash generated during the maintenance service into the trash bag and bring them to the servicing office. Record the service details and the consumables and parts replaced at visit in the Machine Service Log. DocuPrint 2050 weighs 14.8kg. Always have 2 or more people available to move the printer.

Chapter 2 Troubleshooting

2.1 Advancing Troubleshooting

NOTE

This chapter describes the Fuji Xerox Printing Systems standard spe cifications and cases where the printer controller is normal. When the printer controller directly controls the device or the unique specifications of the OEM destination is provided, troubleshooting varies depending on the specifications of the OEM destination.

This manual explains the troubleshooting based on the operations, indication s, and running at use of the diagnostic tool (maintenance tool). This system is configured so that troubleshooting is possible even when the diagnostic tool is not used; so, understand the fault analysis procedure before troubleshooting.

2.1 Advancing Troubleshooting

To effectively perform troubleshooting, confirm the phenomenon and preche ck the operation while referring to the FIP (Fault Isolation Procedure) and Chapter 6, "Maintenance Guide".

1) The power voltage is within the specifications. (Measure the voltage at an outlet.)

2) There is no damage, short, cut-off, or connection error in the cable AC.

3) Exactly ground the device.

4) Do not install the device in a high-temperature, high-humidity, low-temperature, or low-humidity place, or a place where the temperature changes extremely.

5) Do not install the device near city water, humidifier, heater, or fire, or dusty place, or a place exposed to the blow from the air conditioning equipment.

6) Do not install the device in a place where volatile or combustible gas occurs.

7) Do not install the device in a place exposed to the direct rays of the sun.

8) Install the device in a well-ventilated place.

9) Install the device in a solid, stable, and horizontal place.

10) The papers conform to the specifications. (standard papers recommended)

11) No error occurs during handling of the device.

12) The parts to be replaced periodically are replaced for the specified number of prints.

2.1.3 Notes on Work

1) Unless required, be sure to disconnect the power cable AC.

WARNING

2) When removing the top cove r of this device and turning the power on for check work, be sure to disconnect the P/J105 and P/J106 connectors on the PWBA MCU XFABK(B) unless especially required.

WARNING

3) When touching a heated part, take care that you do not get burnt.

4) To remove the human e lectr ostatic power of the o pera tor, wear th e wr ist band a nd groun d via the human body.

While the power is turned on, do not absolutely touch the powered parts. The switch and inlet are powered even if the power is turned off. Do not absolutely touch the powered parts.

When removing the top cover and turning the po wer on f or che ck work, laser beams may be radiated from the ROS ASSY. Be sure to disconnect the P/J105 and P/J106 connectors on the PWBA MCU XFABK(B) unless especially required.

Chapter 2 Troubleshooting

2.1 Advancing Troubleshooting

2.1.4 Notes on Using FIP

1) If troubleshooting is still impossible, replace the major check parts listed at initial check and related parts in sequence.

2) When using the FIP for troubleshooting, a normal PWBA MCU XFABK(B) and Drum/toner cartridge may be required to isolate a fault.

3) Confirm the easy check items ag ain at initial check in the FIP, and also check the major check parts, component parts, and related parts.

4) Unless especially required, be sure to disconnect the power cable AC. Do not absolutely touch the powered parts other than the required ones as the power cable remains connected.

5) Unless especially specified, set "Turn on" in the FIP in online mode.

6) The connectors indicate the following contents: “P/J12,CN12” The P/J12 and CN12 connectors are connected. “P12,CN(P)12” Plug side when the P/J12 and CN12 connectors are disconnected (except when they are directly attached to the board) “J12,CN(J)12” Jack side when the P/J12 and CN12 connectors are disconnected (except when they are directly attached to the board)

7) To measure the CN1-2PIN<=>P/J3-4PIN in the FIP, connect the plus side of the measuring instrument to 2PIN of CN1, and the minus side to 4PIN of P/J3.

8) To measure CN1<=>P/J2 in the FIP, refer to Section 5, "Connection Wiring Diagram" in Chapter 6, and check all the pins between the CN1 and P/J2.

9) The P/J3-4PIN is necessarily set to SG (signal ground) or RTN (return). Therefore, the FG (frame ground)/SG (signal ground) is a connection type. Confirm that the FG and SG are powered exactly, and if necessary, connect the minus side to the pin of another SG (or RTN) or frame (FG) instead of the P/J3-4PIN.

10) To measure the voltage with a connector on the PWBA MCU XFABK(B), use the pin of the plug on the top of the connector or terminal side of the connector.

11) To measure the voltage, set the Drum/toner cartridge and Paper Cassette, close the top cover (interlock switch is on), and turn the power on unless especially required.

12) The numeric values shown in the FIP are standard, and the approximate values are allowed.

13) To perform the check shown in the FIP, take care of the check work and necessarily removed parts because there are no instructions .

14) "Replace" in action shown in the FIP indicates the parts assumed to be a fault source, and it means that the operator should replace and check the parts and assembly parts (HIGH ASSY) containing them.

15) The FIP provides a function that decides whether the diagnostic tool (maintenance tool) exists. For troubleshooting, follow the instruction issued from the function.
