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.
