or close to a humidifier or heater. Damage could be caused to the machine in such areas.

5. Do not place candles, burning cigarettes, etc. on the machine, these could cause a fire.

6. The fuser unit works at a high temperature. Use caution when working on the machine. Wait
for the fuser to cool down before disassembly.

Assembly / Dis assembly Precautions

Replace parts carefully, al ways use Xerox parts. Take care to note the exact location of parts and
also cable routing before disman tlin g any p art o f the ma chine . Ensur e all part s and ca bles are re­placed correc tly.

Please carry out t he followi ng procedu res befo re disma ntling th e machine or replaci ng any pa rts.

1. Check the contents of the machine memory and make a note of any user settings. These will
be erased if the mainboard is replaced.

2. Ensure that power is disconnected before servicing or replaci ng any electrical parts.

3. Disconnect printer interfa ce cables and power c ables.

4. Be sure to remove the print cartridge before you disassemble any parts.

5. Only use approved spa re p arts. E nsure that pa rt nu mber , pro duct na me, a ny volt age , curren t
or temperature rating are correct.

6. When removing or re-fitting any parts do not us e excessive forc e, especially when fitting
screws into plastic.

7. Take care not to drop any small parts into the machine.

8. Handling of the OPC Dr um

- The OPC Drum can be ir reparably damaged if it exposed to light.
Take care not to expose the OPC Drum either to direct sunlight or to fluorescent or incandes-

cent room lighting. Exposure for as little as 5 minutes can damage the surface’s photocon­ductive properties and will result in print quality degrad ation. Take extra care when servicing
the machine. Re move the OPC Dru m an d store it in a bla ck bag or other li g htproof conta iner.
Take care when working with the covers (especially the top cover) open as light is admitted to
the OPC area and can damage the OPC Drum.

Introduction

ESD Precautions

Certain semiconducto r devices can be easily damaged by static electric ity. Such components a re
commonly called “Electrostatically Sensitive (ES) Devices”, or ESDs. Examples of typical ESDs
are: integrated circuits, some field effe ct transistor s, and semiconductor “chip” components.

The techniques outlined below should be followed to help reduce the incidence o f c omponent
damage caused by static electricity.

CAUTION

Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.

1. Immediately before handling a semiconductor component or semiconductor-equipped
assembly, drain off any electrostat ic charg e on your body by touching a known ear th ground .
Alternatively, employ a commercially available wrist strap device, which should be removed
for your personal safety reasons prior to applying power to the unit under test.

2. After removing an electrical assembly equipped with ESDs, place the assembly on a conduc­tive surface, such as aluminium or copper foil, or conductive foam, to prevent electrostatic
charge buildup in the vicinity of the assembly.

3. Use only a grounded tip so ldering iron to solder or desolder ESDs.

4. Use only an “anti-static” solder removal device. Some solder removal devices not classified
as “anti-static” can generate electrical charges sufficient to damage ESDs.

5. Do not use Freon-prope lled chemi cals. When sprayed, these can genera te electrical charges
sufficient to damage ESDs.

6. Do not remove a replacement ESD from its protective packaging until immediately before
installing it. Most repl ace ment ESDs are packaged with all leads shorted together by conduc­tive foam, aluminium foil, or a comparable conductive material.

7. Immediately before removing t he pro tective shor ting mate rial from the lea ds of a replacem ent
ESD, touch the protect ive material to the chassis or cir cuit assembly into which the de vice will
be installed.

8. Maintain continuous electrical contact between the ESD and the assembly into which it will be
installed, until completely plugged or soldered into the circuit.

9. Minimize bodily motions when handling unpackaged replacement ESDs. Normal motions,
such as the brushing together of clothing fabric and lifting one’s foot from a carpeted floor,
can generate static electric ity sufficient to damage an ESD.

IQ 20 Signs and Measures of Poor Print Cartridge

Table 1:

Fault Signs Cause & Check Solution

Light image and par­tially blank image
(The life is ended.)

• The printed image
is light or unclean
and untidy.

• Some part of the
image is not printed.

• Periodically a noise
as "tick tick" occurs.

1. If the image is light or
unclean and untidy printed
image -Shake the print car­tridge and then recheck.
(1)NG: Check the weight of
the print cartridge
(2)OK: Lack of toner, so the
life is nearly closed.

2. Some part of image is not
printed -Shake the print car­tridge and then recheck.
(1)NG: Check the weight of
the print cartridge and clean
the LSU window with a cotton
swab, then recheck.
(2)OK: Lack of toner, so the
life is nearly closed.

3. Periodically a noise as "tick
tick" occurs - Measure the
cycle and the weight of the
print cartridge.

4. White vertical stripes on the
whole screen or partly: Check
the weight of the print car­tridge.

1. All of 1, 2, 3 above-If it
become better by shaking,
replace with a new print car­tridge after 50-100 sheets in the
closing state of the life span.

2. In case of 2-If it becomes bet­ter after cleaning the LSU win­dow, then the print cartridge is
normal. (Because of foreign
substance on the LSU window,
the image has not been printed
partly.)

3. In case of 3-If the cycle of
noise is about 2 seconds, the
toner inside the print cartridge
has been nearly exhausted.
(Purchase and replace with a
new print cartridge after using
about 200 sheets at the point of
occurrence)

4. In case of 3-This is a phe­nomenon caused by lack of
toner, so replace with a new
print cartridge.

Toner Contamina­tion

3-24 5/08 Phaser 3435

• Toner is fallen on
the papers periodi­cally.

• Contaminated with
toner on prints partly
or over the whole
surface.

1. Toner is fall en on th e paper
periodically.
(1)Check the cycle of the fall­ing of the toner.
(2)Check the appearance of
both ends of the print car­tridge OPC drum.

2.The centre of the printed
matter is contaminated with
toner.
(1)Check whether foreign
substances or toner are stuck
to the terminal (contact point)
of the print cartridge.
(2)Check whether the state of
the terminal assembly is nor­mal.

1. If both ends of the OPC drum
are contaminated with toner:
Check the life of the print car­tridge.

2. Check whether it could be
recycled.

3. If it cannot be recycled:
Replace the print cartridge.

Image Quality

Table 1:

Fault Signs Cause & Check Solution

White Black spot • Light or dark black

dots on the image
occur periodically. •
White spots occur in
the image periodi­cally.

1. If light or dark periodical
black dots occur, this is
because the print cartridge
rollers are contaminated with
foreign substance or paper
particles.
(1)38mm interval: Charge d
roller
(2)95mm interval: OPC cycle

2. If white spots occur in a
black image at intervals of
95mm, or black spots occur
elsewhere, the OPC drum is
damaged or foreign sub­stance is stuck to the surface.

3. If a black and white or
graphic image is partially bro­ken at irregular intervals, the
transfer roller's life has been
expired or the transfer voltage
is abnormal.

1. In case of 1 above -Run OPC
Cleaning Mode Print 4-5 times
repeatedly to remove, refer to

GP 5

. Especially check foreign
substance on the OPC surface,
then remove them with a clean
gauze moistened with IPA (Iso­propyl Alcohol) not to damage
OPC if necessary. Never use
usual alcohol.

2. In case of 2 If they are not
disappeared by running OPC
Cleaning Mode Print 4-5 times.:
at intervals of 38mm -Replace
the print cartridge.: at intervals
of 95mm - Remove foreign sub­stance.: Broken image -Replace
the print cartridge according to
carelessness.

3. In case of 3 -Exchange the
transfer roller because the life of
the transfer roller in use has
been expired. (Check the trans­fer voltage and readjust if differ­ent.)

Recycled product • Poor appearance

of the print cartridge.

• Unclean and rough
printouts. • Bad
background in the
image.

1. Poor appearance of the
print cartridge.
(1)Check the damage to label
and whether different materi­als are used .
(2)Check the appearance of
parts of the print cartridge,
such as frame, hopper.

2. Unclean and rough print­outs.
(1)Check whether foreign
substance or toner are stuck
to the terminal (contact point)
of the print cartridge.
(2)Check whether the state of
the terminal assembly is nor­mal.

1. In case of 1
(1)If there is an evidence of dis­assembling the print cart ridge .
(2)If materials other than normal
parts of the print cartridge are
added or substituted.

2. In case of 2 -If there are any
abnormality in connection with
the situation of 1.
(1)It occurs when the print car­tridge is recycled over 2 times.
(2)If toner nearly being expired
are collected to use, it is judged
as the recycled print cartridge.

Ghost & Image Con­tamination

• The printed image
is too light or dark, or
partially contami­nated black. • Totally
contaminated black.
(Black image printed
out) • The density of
printouts is too dark
and ghost occurs.

1. The printed image is too
light or dark, or partially con­taminated black.
(1)Check whether foreign
substance or toner are stuck
to the terminal (point of con­tact) of the print cartridge.
(2)Check whether the terminal
assembly is normal.

2. Totally contaminated black.
(Black image printed out)
(1)Check whether foreign
substances are stuck to the
terminal (point of contact) of
the print cartridge and the
state of assembly. (Espe­cially check the charged roller
terminal.)

3. The printed image is dark
and ghost occurs.
(1)Check foreign substance
attached to the terminal (point
of contact) of the print car­tridge and the state of assem­bly. (Especially check the
developing roller terminal.)

1. All of 1, 2, 3 above
(1)Remove toner and foreign
substances adhered to the con­tact point of the print cartridge.
(2)The contact point of the unit
facing that of the print cartridge
also must be cleaned.
(3)If the terminal assembly is
unsafe: • Fully stick the terminal
to or reassemble it after disas­sembling. • Disassemble the
side plate and push the terminal
to be stuck, then reassemble it.

2. In case of 2 It is a phenome­non when the OPC drum of the
print cartridge is not electrically
charged. Clean the terminals of
the charged roller, then recheck
it.

3. In case of 3 It is a phenome­non as the developing bias volt­age of the print cartridge. Clean
the terminals of the developing
roller, then recheck it.
