Service Tasks

　

○Purpose : Here, we will learn about the various tasks the service person is expected to carry out to perform for the purpose of maintaining a specific level of machine performance.

　

　

●Outline

Let’s take a look at the tasks of the service person associated with the fixing system. To obtain a detailed description, click the appropriate item.

Item Description 1 Parts replacement Click to learn about the work you must always carry out after replacing a part. 2 Maintenance servicing Click to see the type of work you must perform as part of maintenance servicing. 3 Troubleshooting Click to find out about the work to perform in response to a service error or a simple image fault. 4 Points to note about servicing Click to find out about what to do and what not to do when servicing the machines.

　

　

1. Parts Replacement

Some parts of the machine require adjustment or counter initialization in service mode upon replacement. If you have replaced any of the following, go through the steps given:

■Fixing Film Assembly

If you have replaced the fixing film assembly, you will have to reset the fixing film assembly life counter so that the count will start anew.

Make the following selections in service mode to reset the counter:

　COPIER > COUNTER > DRBL-1 > FX-FILM

■Pressure Roller

If you have replaced the pressure roller, you will have to reset the pressure roller life counter so that the count will start anew.

Make the following selections in service mode to reset the counter:

　COPIER > COUNTER > DRBL-1 > FX-LW-RL

■Fixing Cleaning roller

If you have replaced the fixing cleaning roller, you will have to reset the fixing cleaning roller life counter so that the count will start anew.

Make the following selections in service mode to reset the counter:

　COPIER > COUNTER > DRBL-1 > FX-CL-RL

■Pressure roller bushing

If you have replaced the pressure roller bushing, you will have to reset the pressure roller bushing life counter so that the count will start anew.

Make the following selections in service mode to reset the counter:

　COPIER > COUNTER > DRBL-1 > FX-LW-BR

Each life count is kept in memory on the DC controller PCB. If you have to replace the DC controller PCB, be sure to enter the count that has been read of the previous PCB.

 

2. Maintenance Servicing

The service person is expected to replace, clean, or check the following at specific intervals; perform the work when the end of individual intervals approach:

Item	Parts name		Task	Approximate interval	Remarks
Periodically replaced parts	-		-	-	The fixing assembly does not have parts that must be replaced periodically.
Durables	Fixing film unit	iR2270/2870	replace	every 150,000 prints
		iR3570/4570	replace	every 240,000 prints
	Pressure roller	iR2270/2870	replace	every 150,000 prints
		iR3570/4570	replace	every 240,000 prints
	Fixing cleaning roller	iR2270/2870	replace	every 150,000 prints
		iR3570/4570	replace	every 240,000 prints
	Pressure roller bushing		replace	every 300,000 prints
Periodical serving	Fixing inlet guide		clean	every 120,000 prints	Dry wipe with lint-free paper.
	Film bias static eliminator	iR2270/2870	clean	every 150,000 prints	Dry wipe with lint-free paper.
		iR3570/4570	clean	every 240,000 prints	Dry wipe with lint-free paper.

　

　

3. Troubleshooting

■E000 through 003 (fault in fixing assembly)

If a fault occurs in the fixing assembly, go through the following: (You will have to reset the error code after performing these steps.)

1) replace the fixing film unit.

2) check the connectors between the fixing film unit and the DC controller.

3) replace the DC controller PCB.

　

■E007-0000 (fixing film rotation error)

If a fault occurs in the rotation of the fixing film, go through the following to correct it. (You will need to reset the machine after performing these steps.)

1) check the machine as a whole, and check particularly the gear used to drive the pressure roller of the fixing assembly; then, replace any damaged part.

2) check the marker of the fixing film; if soiled or damaged, clean with lint-free paper or replace the fixing film unit.

3) check the connectors between the fixing film speed sensor (PS8) and the DC controller.

4) replace the fixing film speed sensor (PS8).

5) replace the DC controller PCB.

　

■Setting Fixing Film Cleaning Intervals

By default, the machine cleans the fixing film only in the event of a jam; nevertheless, you can change the intervals by making the following selections in service mode so that the machine will clean the film regardless of jam removal:

COPIER > OPTION > BODY > FIX-CON (Category 2)

0: clean only in response to jam (default)

1: clean during last rotation every 500 prints

2: clean during last rotation every 200 prints

3: clean during last rotation every 100 prints

　

■Soiling at Specific Intervals

The presence of a scratch or dirt on a roller of the fixing assembly will show up as a cyclic fault in output images. You can, therefore, identify the cause of a cyclic fault based on the interval of its occurrence.

If a cyclic fault is noted, consult the following table to identify the cause (roller).

Parts name	Image fault		Interval	Remedy
Fixing film	soiling at specific interval (face of paper)		76 mm (approx.)	Clean or replace the fixing film unit.
Pressure roller	soiling at specific intervals (back of paper)	iR2270/2870	79 mm (approx.)	Clean or replace the pressure roller.
		iR3570/4570	95 mm (approx.)
Delivery roller	Soiling at specific internals (face of paper)		42 mm (approx.)	Clean or replace the delivery roller.

　

　

4. Points to Note About Servicing

■When Handling the Fixing Assembly

∙Be sure to turn off the power before removing the fixing assembly.

　The fixing assembly is extremely hot immediately after printing. Be sure to leave the machine alone for some time before  touching the fixing assembly.

∙Do not ever turn the screw used to lock the fixing film in place. Otherwise, the nip pressure will be affected, possibly leading to fixing faults and jams.

■Points to Note When Handling the Fixing Film Unit

∙ Do not disassemble the fixing film unit in the field.

∙ Do not touch the surface of the fixing film, and take care not to damage it.

　

■Resetting Error Codes

If a fault indicated by a jam code E000 thorough E003 (fault in the fixing assembly) occurs, merely turning off and then on the main power switch will not reset the machine. Make the following selections in service mode to reset the machine:

1) remove the causes of the error.

2) in service mode, make the following selections, and press the OK key.

3) turn off and then on the power switch.

　

■Compatibility of the Fixing Assembly

The fixing assembly of the iR2270/2870 Series machine and that of the iR3570/4570 Series machine are not compatible.
You will not be able to physically install the wrong assembly because of the difference in the number of pins on the AC connector. Check the number of pins before fitting a fixing assembly into the machine.

The iR2270/2870 Series machine and the iR3570/4570 Series machine also differ in terms of assembly components as can be learned from the following table:

Parts name iR3570/4570 iR2270/2870 Fixing film unit Thickness of the fixing film Pressure roller 30 mm in diameter 25 mm in diameter Pressure roller bushing bearing + molded housing molded bushing
