TROUBLESHOOTING


T-1

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

6. Controller Firmware Update Instructions1. 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 data18A5: in the process of updating the data18A6: completion of updatingDo 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 fail-ure 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.
