3.2 Driving units

When servicing gears or other driving units, be sure to turn them OFF and plug off. Drive them manually

when required.

Never touch the gears or other driving units while the printer is running.

3.3 High-temperature units

When servicing high-temperature units (securing unit, etc.), be sure to turn them OFF to prevent burns,

injuries and other troubles, remove the power plug and start service processes after they have cooled down

enough.

Immediately after completion of operation, they are still hot. Start services after more

than 40 minutes.

3.4 Laser beams

•If your eyes are exposed to laser beams, you may lose your eyesight.

•Never open the cover if warning label for laser beams is attached there.

•Before disassembling and reassembling this laser printer, be sure to turn it OFF.

•When servicing this laser printer while it is running, be sure to follow the

procedures specified in this manual.

•You should understand the features of the laser beams which are capable of

having an injurious action on the human body, not to extend the danger over the

workers as well as other people around the printer.

Laser beams have features as follows:

•Frequencies are smaller in width than other beams (sun and electric bulbs) and

phases are uniform so that high monochromatic and convergence performance

can be obtained and thin beams of light can reach places at a long distance.

•Due to the high convergence, beams are concentrated in high density and high

temperature, which is dangerous to human body.

Reference: Laser beams of this laser printer is invisible rays which you cannot see.

Chapter 1 Troubleshooting

Troubleshooting in this manual assumes use of Diag. tools (maintenance tools).

However, the troubleshooting allows for the case where the Diag tools are not used.

You can correct troubles according to these troubleshooting procedures after

understanding them well.

1. Progressing with the Troubleshooting

After making sure of actual condition of a trouble, proceed with the troubleshooting process making use of

the Fault Isolation Procedure (FIP), “Operation of Diagostics” (Chapter 2), “Plug/Jack (P/J) Connector

Locations” (Chapter 7), and “Principles of Operation” (Chapter 6).

1.1 Flow of Troubleshooting

Flow of the troubleshooting is as follows:

Prior check

Condition check

1.2 Preparatory Requirements

Be sure to check the following items before starting any troubleshooting procedures:

1) Voltage of the power supply is within the specifications (measure the voltage at the electric outlet).

2) Power cord is free from breakage, short-circuit, disconnected wire, or incorrect connection in the power

cord.

3) The laser printer is properly grounded.

4) The laser printer is not installed at a place subjected to too high temperature, too high humidity, too low

temperature, too low humidity or rapid change of temperature.

5) The laser printer is not installed close to water service, humidifier, heat generating unit, or fire, in very

dusty place, or a place exposed to air flow from the air conditioning system.

6) The laser printer is not installed in a place where volatile gas or inflammable gas is generated.

7) The laser printer is not installed under direct sunbeams.

8) The laser printer is installed in a well-ventilated place.

9) The laser printer is installed on a stout and stable plane.

10) Paper used meets specifications (standard paper is recommendable).

11) The laser printer is handled properly.

12) Parts which should be periodically replaced are replaced each time when specified number of sheets

have been printed.

1-26

Chapter 1 Troubleshooting

1.3 Cautions for Service Operations

1) Be sure to remove the power cord except when it is specifically required.

If the printer is kept ON, never touch the conductive parts while it is not specifically

required.

The power switch/inlet of LVPS is live even while the power supply is cut off. Never

touch the live parts.

2) When checking some parts with covers removed and with the interlock and safety and power switches

ON, remove the connector (P/J151) on the ROS ASSY except when it is specifically required.

When checking some parts with covers removed and with the interlock and safety and

power switches ON, laser beams may be irradiated from the ROS ASSY. Since it is

dangerous, be sure to remove the connector (P/J151) while it is not required.

3) When checking some parts with the left cover removed and power ON, be sure to remove the

connector (P/J5011) on the HVPS while it is not required.

When checking some parts with the left cover removed and power ON, high voltage

may be applied by the HVPS. Be sure to remove the connector (P/J5011) on the HVPS.

When connecting the connector (P/J5011) on the HVPS according to the instructions

of the FIP, never touch the HVPS and parts of high voltage.

4) When using Diag. tools or other tools of high voltage, be sure to keep them covered except when

otherwise specified.

When using Diag.Tool or other tools of high voltage, never touch parts of high voltage.

When using Diag.Tool or other tools of high voltage, be sure to follow the procedure of

this manual.

5)When operating the driving units using the Diag or other tools, be sure to keep them

covered unless otherwise specified.

When operating the driving units using the Diag or other tools, never touch the driving

units. When operating the driving units using Diag or other tools, be sure to observe

the procedures in this manual.

6) When touching hot parts, be careful not to get burnt.

7) Workers should wear a wrist band or the like to remove static electricity from their body, grounding

their body while working.

1-27

1.4 Cautions for FIP Use

1) It is assumed in the FIP that the printer controller (CONTROLLER PWB) is normally functioning. If the

trouble cannot be corrected by troubleshooting, replace the printer controller with a normal one and

check for proper operation again.

If the trouble is still not corrected, replace the major parts and then related parts in succession and

confirm according to the procedure of the "Initial check" and "Major check parts".

2) When troubleshooting according to the FIP, normal HNB MCU PWB, Imaging Unit (PHD) or other

parts may be necessary for isolation of failed parts. Prepare them in advance.

3) In the initial check according to the FIP, check only items which can be simply checked.

4) In the initial check according to the FIP, check the constitutive parts of the major check parts and

related parts, as well as major check parts.

5) When working with the printer, Be sure to remove the power cord except when required specifically.

Never touch live parts if not required, while the power cord is connected.

6) Connector condition is denoted as follows:

[P/J12] → Connector (P/J12) is connected.

[P12] → Plug side with the connector (P/J12) removed (except when attached directly to the board).

[J12] → Jack side with the connector (P/J12) removed (except when attached directly to the board).

7) [P/J1-2PIN <=> P/J3-4PIN] in the FIP means measurement with the plus side of the measuring instru-

ment connected to [P/J1] and the minus side to [4PIN] of [P/J3].

8) [P/J<=>P/12] in the FIP means measurement for all terminals corresponding between [P/J1] and [P/J2]

referring to "Wire connecting diagram".

9) In [P/J1-2PIN <=> P/J3-4PIN] in the FIP where voltage is measured, [P/J3-4PIN] on the rear minus

side is always at the AG (analog ground), SG (signal ground), or RTN (return).

Therefore, after checking of proper continuity between AGs, SGs, or RTNs respectively, the rear minus

side can be connected to the PIN of AG, SG or RTN instead of [P/J3-4PIN].

However, care should be taken not to mistake since [AG], [SG], and [RTN] are not on the same level.

10) Measure the voltage of small connectors with the special tool. Handle the tool with care, as the leading

edge of the tool is pointed.

11) When measuring the voltage, set the PDH ASSY, FUSER ASSY, BRT ASSY and paper tray, close the

FRONT COVER ASSY and power ON if not required specifically.

12) Numerical values in the FIP are only for standard. If numerical values are approximate, they should be

considered permissible.

1-28

Chapter 1 Troubleshooting

13) Parts which are always removed to check as indicated in the FIP and procedures for that purpose are

not specifically referred to here. They should be handled carefully.

14) "Replacement" in the FIP indicates replacement of parts which are considered to be the source of trou-

ble to be checked after replacing those parts, assemblies containing them, or parts (HIGH ASSY).

15) In the FIP, the paper pick-up unit by means of the paper tray at the lower part of the printer is referred

to as "try 1", the first level of the paper pick-up unit feeder unit as "try 2", and the second level as the

"tray3".

16) In the FIP, existence and non-existence of Diag tools (maintenance tools,) are distinguished in some

cases. Correct troubles according to the instructions in the FIP.

17) In the FIP, procedures are differentiated depending on specifications. Correct troubles according to the

instructions in the FIP.

18) For optional parts, some troubleshooting procedure may follow the manual for those options, of which

you should take note.

Keep those manuals for the optional parts when required.

3.5 Image Trouble FIP

The descriptions below assumes that the printer controller works normally. By testing

the printing operation for the engine only, conditions can be isolated simply to

determine whether the trouble exists on the printer controller side or engine side.

When the test print with the engine only is correct, the printer controller is fault.

◆

When printing on the engine only is not correct, the engine is faulty.

◆

When trouble is considered to be on the printer controller side, replace the printer con-

troller with proper one and check for proper operation again.

If the trouble persists even after the replacement, check the host side using the image

FIP for each condition as described below for effective troubleshooting.

If print image quality trouble occurs, print on paper of letter or A4 size in order to judge and understand the

trouble precisely and take proper remedy steps. Use the image quality FIP correction table to diagnose the

trouble.

If the problem cannot be corrected according to the image quality FIP, check the trouble after replacing the

"Major check parts" specified for the "Initial check" in the image quality FIP in succession.

Image quality FIP describes the representative image quality troubles as follows:

✧

FIP-1.P1 "Light (Undertoned) Prints"

✧

FIP-1.P2 "Blank Prints"

✧

FIP-1.P3 "Black Prints"

4. Preventive Maintenance

When you visit a customer, perform preventive maintenance services irrespective of the major object of

your visit to prevent possible troubles beforehand.

◆

Preventive maintenance procedure

1) Ask the customer how the laser printer is used.

2) Record the accumulated number of sheets printed.

Replace the parts to be replaced periodically based on the number of prints. If

required, replace such parts at this time.

3) Print on several sheets of paper to check for proper operation.

4) Remove foreign substances on the Transfer Unit (BTR), Imaging Unit (PHD), FUSER ASSY and paper

delivery rolls and clean stains with a brush or dry cloth.

If stain is serious, clean with wet cloth and then dry cloth. Be careful not to damage the

parts at this time.

5) Cleaning of fan exhaust port

Remove the FRONT HEAD COVER and clean the FUSER FAN to remove dust deposited on it with a

brush. Remove the REAR COVER and clean the dust deposit on the fan.

If the exhaust port or fan is clogged, temperature in this laser printer increases

causing trouble.

6) Print on several sheets again to check for proper operation.

Chapter 2 Operation of Diagnostics

1. Diagnostics for a Standalone Printer

1.1 General

The test print can be used on a standalone printer for operational check. For this purpose, the test print

pattern stored in the printer is printed continuously at the continuous printing speed.

1.2 Printing Method

1) Remove the magicolor 3100 Controller Board. (See Disassembly and Assembly 12.3.)

2) Put paper in tray 1, and turn the power on.

In the following steps, never touch live parts or driving parts.

3) Short the two pins of the test print connector (P31) on the PWBA HNB MCU.

Reference: To short the two pins, use the tip of a screwdriver to touch both pins at the same time.

4) The printer goes into a READY mode and starts printing. (Printing is carried out continuously in the

Duplex mode).

5) To stop the printing, remove the short from the two pins.

The paper is fed from tray 1 only, and if no paper is in tray 1, printing is not carried out.

Reference:Printing will not start if the printer has an error.

Reference: For the READY mode, see 6.2 Operation Modes in Section 6 “Principle of Operation”.
