TROUBLESHOOTING

��

��


1. INTRODUCTION1-1. General Precautions• When replacing a part or plugging or in unplugging a connector, always make sure that

the power cord of the copier has been unplugged.• Never create a closed circuit across connector pins except those specified in the text and

on the printed circuit.• When energizing the controller with its cover removed, use utmost care not to touch a

board or any other component inside it.• The basic rule is not to run the controller with any of its parts removed.• When the user is using a word processor or personal computer from the power outlet of

the same line, take necessary steps to prevent the circuit breaker from opening due to overloads.

• Keep all disassembled parts in good order and keep tools under control so that none will be lost or damaged.

1-2. Reading the Text• If a component (except fuses) on a PWB or any other functional unit including the HDD is

defective, the text only instructs you to replace the whole PWB or functional unit and does not give troubleshooting procedures applicable within the defective unit.

• All troubleshooting procedures contained herein assume that there are no breaks in the harnesses and cords and all connectors are plugged into the right positions.

• The text does not contain the removal procedures of covers and parts. See DIS/REAS-SEMBLY of the Service Manual for copier.

• The procedures preclude possible malfunctions due to noise and other network prob-lems.

1-3. Network Problems• Any problem that occurs in conjunction with the operation of the controller over a network

should be directed to the network administrator for check and repair. The servicemen should never attempt to make network-related settings or repair network-related prob-lems.

• The user should only ask for a check on network-related wiring from the network to the

T-1

controller and should never attempt to check it out him/herself.


2. STATUS CODES• If the controller is ready to communicate, it notifies the copier of the code (18XX).

3. REMEDIAL PROCEDURES• The basic repair procedure for the controller is to replace the defective PC board or other

unit with a new one.• First, identify the faulty symptom and replace the defective part to restore the controller

to the normal operating condition.

3-1. Printing is Not Possible Via Parallel Port

(1) Checking Printer cable for connection

• After turning the copier power OFF, check the printer cable for proper connection to the controller. Then, turn the copier power ON again.

Step Check Result Action

NG Reconnect cable and turn ON the copier power again.

OK Go to step 2.

2 Check the power harness for correct voltage.

NG Change the DC Power Supply Main of the machine.

OK Go to step 3.

3 Check the controller connector (J2) for proper connection to the Image Processing Board.

NG Reconnect connector and turn ON the copier power again.

OK Go to step 4.

4 Check DIP Switch settings on, and connector connection to, the Main Board.

NG Correct faulty spots and turn ON the copier again.

OK Change the Main Board.

T-4

(2) Checking power harness for correct voltage

• When the Power Switch is turned ON:Voltage across Main Board J11-1 and GND: DC 5 VVoltage across Main Board J11-5 and GND: DC 3.3 V

Printer Cable

4692O002AB


(3) Checking controller connector (J2) for proper connection to Image Processing

Board

• The Main Board should be properly connected to the Image Processing Board of the machine. (☞ T-6)

(4) Checking DIP switch settings and connectors on Main Board

• Check that DIP SW1 to SW4 are all OFF. (☞ M-8)• Check that DIMM is properly inserted into the socket. (☞ D-4)

3-2. Printing is Not Possible Via Network

(1) Checking cable and connector for connection

• After turning the copier power OFF, check the NIC Board cable for proper connection to the controller. Then, turn the copier power ON again.

(2) Checking LEDs on the NIC Board

• Check that the green LED is ON. (☞ M-9)

Step Check Result Action

1 Check the cable and connector on the NIC Board for proper connection.

NG Reconnect cable and connector and turn ON the copier power again.

OK Go to step 2.

2 Check LEDs on the NIC Board for proper indication.

NG Change the NIC Board.

OK Go to step 3.

3 Check correct printing through paral-lel port.

NG Perform troubleshooting procedures of “3-1. Printing is Not Possible Via Parallel Port”.
