l-l. General Precautions

When servicing the copier 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.

2. Before attempting to replace parts and unplug 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 a 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.

7. Adjust, choice, count, and other types of data are stored in TC3 (EEPROM) on Master Board PWB-A. Keep this in mind and take necessary precautions when replacing PWB-A.

How to Use This Book

If a component on a PWB or any you to replace the whole 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

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.

1-3. Reading the Text

The paper transport failure troubleshooting procedures are given according to the symptom. First identify the location where the paper is present and 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.

2-1. Misfeed Detection Types and Detection Timings

When a misfeed occurs, the corresponding misfeed code (the appropriate one of those shown below) starts blinking to let the user know where the misfeed has occurred.

Misfeed Code

Type

Paper take-up misfeedl Paper Transport Sensor PC2 is not blocked or Paper empty after the lapse of approx. 3.3 sec. after Paper

Take-Up Solenoid SL2 has been energized.

Paper Transport Sensor PC2 is not blocked (L) even after the lapse of approx. 1.6 sec. after Multi Bypass Paper Take-Up Solenoid SL3 has been energized.

Transport misfeed

Paper Exit Sensor PC3 is not blocked (L) even after the lapse of approx. 2 sec. after Registration Clutch

CL1

has been energized.

PC2 is not unblocked (H) even after the lapse of approx. 2.9 sec. (Cassette) or 3.2 sec. (Manual bypass) after Registration Clutch CL1 has been energized.

Exit misfeed

Paper does not move past Paper Exit Sensor PC3 even after the lapse of approx. 3 sec. after PC2 has been unblocked (H).

PC3 remains blocked for approx. 2 sec. after CL1 has been energized.

SDH misfeed

SDH Paper Transport Sensor PC23 is not blocked (L) even after the lapse of approx. 2.3 sec. after SDH Paper Take-Up Solenoid

SDH Original Exit Sensor PC24 is not blocked (L) even after the lapse of approx. 1.3 sec. after SDH Registration Clutch CL10 has been energized.

PC23 is not unblocked (H) even after the lapse of

approx. 4.4 sec. after
