1-1. General Precautions

1. When servicing thecopier with its covers removed, use utmost care to prevent your hands, clothing, and tools from being caught in revolving parts including the chains and gears. When servicing the copier with the Lower Rear Cover removed, be sure to install the jig.

2. Before attempting to replace parts and unplugging connectors, make sure that the power cord of the copier has been unplugged from the wall outlet.

3. Never create a closed circuit across connector pins except those specified in the text and on the printed circuit.

4. When creating a closed circuit and measuring a voltage across connector pins specified in the text, be sure to use the green wire (GND).

5. When the user is using a word processor or personal computer from the wall outlet of the same line, take necessary steps to prevent the circuit breaker from opening due to overloads.

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

1139SBT0102A

1-2. How to Use This Book

1. If a component on a PWB or any other functional unit including a motor 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.

2. 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.

3. For the removal procedures of covers and parts, see DIS/REASSEMBLY, ADJUSTMENT.

4. The troubleshooting procedures are given in the order of greater frequency of trouble or order of operation.

5. The procedures preclude possible malfunctions due to noise and other external causes.

1139SBT0103A

1-3. Reading the Text

1. The paper transport failure troubleshooting procedures are given according to the symptom. First identify the location where the paper is present and start the procedure for that particular location. For malfunction troubleshooting, start with step 1 and onward.

2. Make checks in numerical order of steps and, if an item is checked okay, go to the next step.

I/O PORT CHECK2

1156SBT0201A

2-1. Controlled Parts Check Procedure

To allow the Tech. Rep. to easily and safely determine whether a particular controlled part is fully operational, this copier provides the following provision: checking the data of the I/O port of the board IC with the copier in the standby state (including a misfeed, malfunction, and closure failure condition) allows the Tech. Rep. to determine whether a signal is properly input to, and output from, a controlled part.

1) On the circuit diagram accompanying the text, locate the I/O port of the controlled part which is probably defective when a misfeed or malfunction occurs.

2) Select the “IC Port Data Check” function of “I/O Check” in the Tech. Rep. mode and access the screen which contains the port identified in step 1 above. (See SWITCHES ON PWBs/TECH. REP. MODE.)

3) Change or check the input or output port data to determine whether the controlled part is operational and signals are properly input and output.

4) If the controlled part does not operate properly after changing the output port data, select “Controller Board Check” of “I/O Check” in the Tech. Rep. mode and determine whether the board is responsible for that malfunction or not.

Note: Only the output ports given on pages T-37 and 38 may be checked by “Controller Board Check”

of “I/O Check” in the Tech. Rep. mode.

C03## Master Board/Harness Malfunctions

The copier performs a self-diagnostic sequence to determine if the microprocessor outputs a signal to

each of the IC ports on Master Board PWB-A properly. It is intended for detecting the following malfunctions (C03##). Any malfunction is detected when “Controller Board Check” available from the “I/O Check” function of the

D

Tech. Rep. mode is executed. If the microprocessor fails to output any of these signals or if any of the electronic components on the board

D

(driver IC, etc.) is faulty,the copier determines that there is a faulty condition existing and shows the corresponding malfunction code on the Touch Panel. C0350, C0351, C0352, C0353, or C0357 is displayed when there is a communication fault between the

D

copier and paper feeder option or Duplex Unit, and detected as an isolated malfunction when the Power Switch is turned ON.

2) A solid black pattern is produced and the PWB-G output is sampled.

3) If the average is less than 4.3V, Vg is increased.

In the initial F5 or FF mode:

1) The Exposure Lamp is turned ON with 58V.

2) A halftone pattern is produced and the PWB-G output is sampled.
