Chapter 1 Service Call Procedure

1.1 Before Starting the Servicing

1-2

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 much intake of the solvent.

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 cleaner

and not a customer's cleaner. Also, as the developer also contains toner, exercise the same

caution during cleaning.

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

1-3

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

For the separation and processing methods for the collected items, refer to the

Common Technical Information No. 2-138 for all machines.

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.

Refer to the Installation Procedures for details.
