TROUBLESHOOTING
Page 24
1. INTRODUCTION
1-1. 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/REAS­SEMBLY of the Service Manual for copier.
The procedures preclude possible malfunctions due to noise and other network prob­lems.
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 prob­lems.
The user should only ask for a check on network-related wiring from the network to the controller and should never attempt to check it out him/herself.

A mismatch is detected in version numbers.
Factory settings are recovered through DIP switch setting.
NIC error: NIC initialization has failed.
Version error: A mismatch is found between the program utility function ver­sion and ROM disk utility function version.
Flash ROM update data being loaded: The controller notifies, after accepting a flash ROM update request, that update data is being downloaded. It has sus­pended some of its functions and the job being processed can be terminated or discarded.
The power should not be shut down while this notification is
being issued.
Flash ROM update data being written: The controller notifies that update data, which has been down­loaded, is being written in flash ROM.
The power should not be shut down while this notification is
being issued.

Flash ROM update data loading failure: The area required for downloading update data is not available or there is an error found in update data.
Flash ROM update data writing failure: Writing in flash ROM has failed.
The data in ROM might have been destroyed and it is likely
that the controller cannot recover.
Scan job abandoned for short of machine memory space: Short machine memory space results during distribution involv­ing two or more distribution destinations.
Reset 10 min. later or at the start of the next scan job.
Short of memory space during image conversion: A job is abandoned for short of controller memory space during processing of scan jobs.
Reset 10 min. later or at the start of the next scan job.
Scan job NIC internal processing error: Distribution is interrupted by an error response from NIC during distribution processing of scan jobs.
Reset 10 min. later or at the start of the next scan job.

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
Step Check Result Action
1 Check the printer cable for proper
connection.
2 Check the power harness for correct
voltage.
3 Check the controller connector (J2)
for proper connection to the Image Processing Board.
4 Check DIP Switch settings on, and
connector connection to, the Main Board.

After turning the copier power OFF, check the printer cable for proper connection to the controller. Then, turn the copier power ON again.
NG Reconnect cable and turn ON the
copier power again.
OK Go to step 2.
NG Change the DC Power Supply Main
of the machine.
OK Go to step 3.
NG Reconnect connector and turn ON
the copier power again.
OK Go to step 4.
NG Correct faulty spots and turn ON the
copier again.
OK Change the Main Board.
Printer Cable
(2) Checking power harness for correct voltage
When the Power Switch is turned ON: Voltage across Main Board J11-1 and GND: DC 5 V Voltage across Main Board J11-5 and GND: DC 3.3 V

(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
Step Check Result Action

the NIC Board for proper connection.
2 Check LEDs on the NIC Board for
proper indication.
3 Check correct printing through paral-
lel port.
(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)
NG Reconnect cable and connector and
turn ON the copier power again.
OK Go to step 2.

6. Controller Firmware Update Instructions
1. Prepare a computer of which operating system is either one of Windows 95, 98, 2000 or
NT4.0.
2. Connect the PC to the controller with a parallel cable and turn the main switch of the
copier ON. (Before updating the firmware, be sure to print out the Configuration Page.)
3. Turn on the Copier power and wait at least 5 minutes. (It is necessary that the Pi4700e
boot-up completely.)
4. Launch MS-DOS Prompt (for Windows 95/98) or Command Prompt (for Windows
NT4.0/2000) Then enter the following command and press the Enter key.
5. Change current directory to the directory containing the new firmware update file.
e.g. The new firmware update file is in C:\temp. In this case, type cd c:\temp then press Return Key”.
6. Type copy/b File name lpt1”.
7. Check the status on Copier panel. The Printer Controller Error “18A4” is displayed. The
status changes from “18A4”, “18A5” to “18A6”. These codes represent Job Status. 18A4: in the process of loading the data 18A5: in the process of updating the data 18A6: completion of updating Do not turn off the Copier until the “18A6” is displayed.
8. After 18A6 is displayed, turn OFF/ON the Copier power.
*After the completion of updating the controller firmware, in some cases, “18A0” code may be displayed on the copier panel. However, this code do not represent update fail­ure and in the spite of the code indication, the updating has finished successfully. As a precaution, turn the copier switch OFF/ON.
9. The firmware upgrade is completely. Please check the new firmware version from Con-
figuration Page.
