1 INTRODUCTION

1-1. General Precautions

1. When servicing the co pier with its covers remo ved, use utmost c are to prev ent your
hands, clot hin g, and to ols from be ing caug ht in revol vin g parts includin g the chai ns 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 cr ea te a closed c irc uit acros s connecto r pi n s except those s p ecified in the text
and on the printed circ ui t.

4. When creatin g a closed circuit and measuring a volt age across connector pins speci­fied in the text, be sure t o use the green wire (GND).

5. When the user is us ing a word processo r or personal compute r 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.

1-2. How to Use This Book

1. If a component on a PWB or any oth er func tio nal un it inc lud ing a motor is defectiv e , the
text only instructs you to replace the w hole PWB or functi onal unit and does not give
troubleshooting procedure applicable withi n the defect i ve unit.

2. All troub les hoo ti ng pr ocedu res c ontai ned h erei n as sume t hat t he re ar e no b rea ks in th e
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 troub les hoo tin g pr ocedu res are given in the ord er of g rea te r f requ ency of t roub l e or
order of operation.

5. The procedures pre cl ude possi b le malf un ctio ns due t o nois e and ot her e xt ernal cau ses.

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 th at particular locatio n. For malfunction troubleshooting, start with step 1 and
onward.

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

2 I/O PORT CHECK

2-1. Controlled Parts Check Procedure

To al low the Tech. Rep . to easily and safely determine whether a particular c ontrolled part
is fully operational, this copier pro vides the follow ing provision: chec king of the data of the I/
O port on the board IC with the copier in the standby state (inc luding a misf eed, malfunc­tion, and closure failure condition) allows the Tech. Rep. to determine whether a signal is
properly input to, and output from, a controlled part.

<Procedure>

1. When a paper misfeed or malfunction occurs, identify t he I/O port of the possibly defec­tive cont rolled part by reviewing the text or I/ O port check list.

2. Select the I/O Check func tion of the Service mode and show on the Touch Panel the
status of the I/O port identified in step 1.

3. Check the input or output port data to determine whether the controlled part is opera ­tional and signals are properly input and output.

<Controlled Part Check Procedure by Changing Input P ort Data>

Example
When a paper misfeed occurs in the paper take-up section of the copier, 1st Dra wer Paper
Take-Up Sensor PC55 is considered to be res ponsible for it.

<Procedure>

1. Remove the sheet of paper misfed.

2. Fr om the I /O port che c k li st , i t is found that the H/L inpu t sig nal to P C55 i s sup pl ied fr om
PWB-A (IC4A) APA1.

3. Select the I/ O Chec k fu nc tio n fr om the S ervice mode me nu and, usin g th e P a per S elec t
key, show the status of PWB-A (IC4A) APA1 on the control panel.

4. Check that the second LED from the right of the Exposure Level Display ligh ts up (sen­sor being unblocked).

5. Move the PC55 actuator to block the sensor .

6. Check at this time that the LED goes out.
ON: PC55 is faulty. OFF: PC55 is operational.

3-1. Paper Misfeed

When a paper misfeed occurs in the copier, the corresponding Misfeed Location Mon itor
LED on the control panel blink s to let the user know where the misf eed has occurred. If an
LED lights up steadily, it indicates that there might be a sheet of paper present at that par­ticular loc ation in the copier. If a paper misfeed occurs very frequently, carry out the nec es­sary troubleshooting proced ures according to the location of th e misfeed.
