Image Faults
Faint white line on a second side image due to the stain on the Connection Lower Guide Roller for the Primary Fixing Assembly
[Symptom]
A faint white line [a] might appear on a second side image, if the machine is used a lot under the high temperature and high
humidity environment.
The arrow [b] indicates the direction of feeding.
The symptom is easily found on a high density image such as halftone or solid image.
[Cause]
IF the paper having a lot of paper lint is used under high temperature and high humidity environment, the paper lint and wax
component of toner combine and adhere to the Connection Lower Guide Roller [1] located at the outlet for the Primary Fixing
Assembly.
When the paper lint and the wax component of toner which adhere to the roller are transferred to a paper, the above symptom
occurs.
[Service work]
1) Open the Sub Station Front Right Cover to pull out the Primary Fixing Assembly.
2) Clean the whole surface of the Connection Lower Guide Roller with lint-free paper moistened with alcohol rotating the roller
by hand.
3) Output the image having shown the symptom, and check that the symptom does not occur.
If the symptom does not improve, then check other factors.
1
Uneven gloss (Rain drop mark) in the high-density area in usage of OHT
[Symptom]
Uneven gloss (Rain drop mark) [a] may occur in the high-density area in usage of OHT.
The arrow [b] indicates the direction of feeding.
[Cause]
Since the thickness and components of OHT vary depending on the kind, quantity of heat required for toner to fix on the film also
varies.
In case an excessive temperature is added on OHT, toner tends to melt beyond necessity.
The difference in glossiness made between the area where toner melts beyond necessity and the other image area causes the
above-mentioned symptom.
[Service work]
1) Have the customer log in from System Management Mode in user mode.
2) Go to Select Settings/Registration > Paper Settings > Paper Type Management Settings, select an appropriate paper type
from among the list, press "Duplicate" button and then "OK" button.
3) Enter any name as the duplicated paper type and press "OK" button.
2
4) Select the paper type duplicated in the step 3) and press "Details/Edit".
5) Select "Adjust Gross/Fine Black" and press "Change".
[Reference] In case Adjust Gross/Fine Black will not be displayed on the control panel, change the setting value of Service Mode
> Mode List > COPIER > Option > DSPLY-SW > IMGC-ADJ to "1". The value is "0" by default.
6) Press "-" button for gloss, Make sure the setting value [a] is set to "-1" and press "OK".
The setting range is from "-4" to "+4" ("0" by default).
Change of the setting value changes the fixing temperature.
3
[Caution] Changing the value may cause glossiness of image may slightly decrease.
7 ) Output the image having shown the symptom, and check that the symptom does not occur.
If the symptom improvement is inadequate, decrease the setting value of step 6) down to "-3" by "1" value while observing the
symptom.
In case the decreased setting value "-3" of step 6) does not improve the symptom, please check another factor.
4
Horizontal white streaks with 2mm intervals on a high density green image
[Symptom]
In a usage under a low humidity environment, horizontal white streaks [a] with 2mm intervals may occur on a high density green
image
The arrow [b] indicates the direction of feeding.
[Cause]
Being affected by the influence of toner or ITB, the electric current may become uneven even if a constant primary transfer voltage
is applied.
If an electrical discharge phenomenon is generated on a part where has more current after the transfer, the electric charge amount
varies among the toner on the paper.
When the electric charge amount varies, the amount of toner that was once transferred to paper and to be attracted to the drum
(retransfer) at the next station changes, so that the toner amount on the paper becomes uneven and results in the above
mentioned symptom.
A low humidity environment is likely to have this symptom as the primary transfer voltage is large.
[Service work]
1) Have the customer log in from System Management Mode in user mode.
2) Go to Select Settings/Registration > Paper Settings > Paper Type Management Settings, select an appropriate paper type
from among the list, press "Duplicate" button and then "OK" button.
3) Enter any name as the duplicated paper type and press "OK" button.
5
4) Select the paper type duplicated in the step 3) and press "Details/Edit".
5) Select "Adj. Primary Transfer Voltage" and press "Change".
[Reference] In case Adjust Primary Transfer Voltage will not be displayed on the control panel, change the setting value of Service
Mode > Mode List > COPIER > Option > DSPLY-SW > IMGC-ADJ to "1". The value is "0" by default.
6) If the Adjust Primary Transfer Voltage screen is displayed, the presetting is completed.
6
7) Select black under primary transfer voltage, change the correction parameter [a] to "-5" by pressing "-" button and press "OK".
The setting range is from "-10" to "+10 ". ("0" by default)
Change of the setting value changes the primary transfer voltage.
[Caution] Changing this setting may decrease the primary transfer voltage and bring poor image with black (lowering of density,
mottling image, etc.).
8) Output the image having shown the symptom, and check that the symptom does not occur.
If the symptom does not improve, then check other factors.
7
Uneven gloss on the entire high density image
[Symptom]
Uneven gloss [a] may occur on the entire high density image such as solid image.
The arrow [b] indicates the direction of feeding.
[Cause]
The influence of an uneven temperature and uneven cooling of the member (guide etc.) on the delivery path after fixing may
cause the time difference in solidifying the wax components included in the toner.
When there is the time difference in solidifying the wax components, the difference in glossiness on the image surface tends to
stand out, and the above-mentioned symptom occurs.
This symptom is likely to be seen on the high density image with high quantity of toner and heavy paper/coated paper that is fixed
at a high temperature.
[Service work]
1) Have the customer log in from System Management Mode in user mode.
2) Go to Select Settings/Registration > Paper Settings > Paper Type Management Settings, select an appropriate paper type
from among the list, press "Duplicate" button and then "OK" button.
3) Enter any name as the duplicated paper type and press "OK" button.
8
4) Select the paper type duplicated in the step 3) and press "Details/Edit".
5) Select "Adjust Gross/Fine Black" and press "Change".
[Reference] In case Adjust Gross/Fine Black will not be displayed on the control panel, change the setting value of Service Mode
> Mode List > COPIER > Option > DSPLY-SW > IMGC-ADJ to "1". The value is "0" by default.
6) Press "-" button for gloss, Make sure the setting value [a] is set to "-1" and press "OK".
The setting range is from "-4" to "+4" ("0" by default).
Change of the setting value changes the fixing temperature.
9
[Caution] Changing the value may cause glossiness of image may slightly decrease.
7 ) Output the image having shown the symptom, and check that the symptom does not occur.
If the symptom improvement is inadequate, decrease the setting value of step 6) down to "-3" by "1" value while observing the
symptom.
In case the decreased setting value "-3"of step 6) does not improve the symptom, please check another factor.
10
Glossy streaks on high density portion
[Symptom]
Glossy streaks [a] may appear on a high density portion.
The arrow [b] indicates the direction of feeding.
This symptom is more visible with heavy / coated paper.
[Cause]
The surface of the fixing roller may have minute scratches on it due to foreign particles such as paper lint.
The thermal conductance of the scratched portion of the fixing roller is lower than that of surrounding portions and the glossiness
of image of the same portion is reduced.
The difference of the glossiness of the image generates the aforementioned symptom.
[Service work]
1) Select Settings/Registration > Adjustment/Maintenance > Maintenance > Refresh Fixing Roller[1],and press "Start" button[2].
[Reference] The time required for adjustment is approximate 40 seconds.
2) Output the image having shown the symptom, and check that the symptom does not occur. If the symptom no longer occurs,
the work is completed.
If the symptom will not improve, repeat the step 1) for thrice.
3) Output the image having shown the symptom, and check that the symptom does not occur.
If the symptom does not improve, check other causes.

10mm wide glossy lines near 40/80/10mm from the center of the first side of duplex printing
[Symptom]
10 mm wide semi-glossy lines [a] and highly glossy lines [b] may occur at one of near 40, 80, and 120 mm from the center on
the first side of duplex printing.
The arrow [c] indicates the direction of feeding.
[Cause]
The secondary fixing assembly separates thin papers by engaging the fixing separation claw [1] to the pressure roller.
a. when the surface of the pressure roller is lightly scratched by the fixing separation claw, glossiness of the area where the fixing
separation claw comes in contact with decreases and 10mm semai-glossy lines occur. The symptom tends to occur easily when
the pressure roller is new.
b. The pressure roller in the secondary fixing assembly may be polluted in some cases due to paper and/or toner scattering inside
the engine. The pollution is cleaned in the area where the fixing separation claw comes in contact with, so the glossiness is higher
compared to the area where the claw does not come in contact with, causing the 10mm wide highly glossy lines to occur.
[Service work]
1) Depending on the issue, choose and perform one of a) or b) below.
a) When 10mm wide semi-glossy lines occur:
a-1) Select Service mode > Mode List > COPIER > Function > CLEANING > [FX-CLN], and then press the "OK".
[Reference] The time required for adjustment is approximate 1 minute.
[Caution]
- Do not perform more than two times consecutively. Scratches of the pressure roller may get worse.
- When performed too often, the pressure roller and the pressure refresh roller worn out early.
a-2) Output the image having shown the symptom, and check that the symptom does not occur.
If the symptom does not improve, then check other factors.
b) When 10mm wide highly glossy lines occur:
b-1) Select Service mode > Mode List > COPIER > Function > CLEANING > [FX2PR-CL], and then press the "OK".
12
[Reference] The time required for adjustment is approximate 2 minute.
[Caution] When performed too often, the pressure roller and the pressure refresh roller worn out early.

> Test > Printabout10 sheets of duplex Yellow solid "PG ".
b-3) Output the image having shown the symptom, and check that the symptom does not occur.
If the symptom does not improve, then check other factors.
13
1 mm-wide glossy lines at intervals of 5 mm in the high-density area on the first side of duplex printing
[Symptom]
Several 1 mm-wide glossy lines [a] may occur at intervals of 5 mm in the high-density area on the first side of duplex printing.
The arrow [b] indicates the direction of feeding.
[Cause]
After heavy usage, toner may adhere to static eliminator located at the outlet of the first fixing assembly. If toner adheres to the
static eliminator, the static eliminator becomes firm and it rubs the image surface, and the above-mentioned symptom occurs.
This symptom can be seen more clearly on the high-density image having larger quantity of toner.
This symptom cannot be seen clearly on the heavy paper / coated paper since the paper is fixed again in the secondary fixing
assembly.
[Service work]
1) Open the sub station front right cover and take out the first fixing assembly.
2) Fold the five-ply lint-free paper in four, and clean the static eliminator [1] to become unraveled.
3) Insert the first fixing assembly and close the sub station front right cover.
4) Output the image having shown the symptom, and check that the symptom does not occur.
If the symptom no longer occurs, the work is completed.
If the improvement of the symptom is not enough, go to step 5).
5) Have the customer log in from System Management Mode in user mode.
6) Go to Select Settings/Registration > Paper Settings > Paper Type Management Settings, select an appropriate paper type
from among the list, press "Duplicate" button and then "OK" button.

Prevention method for random horizontal lines on a halftone image due to curled ITB from being unused for a long time
[Symptom]
Horizontal lines [a] may appear randomly on a halftone image after leaving the machine for a long time.
The symptom is especially visible in 250mm intervals attributable to a primary transfer roller.
The arrow [b] indicates the direction of feeding.
[Cause]
If a machine is left untouched for a long time, ITB[a] and 8 rollers[b] inside ITB are in contact each other for a long time, and this
condition curls ITB.
The curled part makes tiny space between ITB and the secondary transfer outer roller, therefore discharge phenomenon may be
generated.
If discharge phenomenon is generated, toner on ITB scatters, disarranges the image and this results in the above mentioned
symptom.
[Service work]
The ITB that is curled from being unused for a long time cannot be fixed in a short time. If an ITB is left unused frequently, take
one of the two following measures, a) or b), to prevent ITB from being curled.
a) If ITB is left unused for a long time with the main power ON:
The ITB is rotated every certain period of time to prevent the symptom.
a-1) Go to Service mode (Lv2) > Mode List > COPIER > Option > IMG-TR > and change the setting value of "ITB-MOVE" to "3".
The setting range is from "0" to "10" ("0" by default).
rotated about 60mm every certain period of time.
[Reference] Explain to the customer that the operation noise can be heard even in Sleep (Deep sleep) mode because the service
mode runs every certain period of time.
b) If ITB is left unused for a long time with the main power OFF:
The pressure of the primary transfer roller is released to prevent the symptom.
[Caution]
17
- When starting to use the machine, apply a pressure to the primary transfer roller first. If not, an image failure (poor transfer)
would occur.
- There is no effect on the four locations other than the primary transfer roller.
b-1) Open the Main Station Front Right Cover and the Main Station Front Left Cover.
b-2) Remove the stepped screw (yellow)[a] and turn the 4 Release Levers [b] in the direction of the arrow, Holding the 2 grips[c],
remove the Intermediate Transfer Unit Cover
b-3) Turn the 2 Release Levers [a] of the Intermediate Transfer Unit in the direction of the arrow at the same time, and pull the
Intermediate Transfer Unit out until it stops by holding the grips[b].
[Caution] Be sure to hold only the [a] part of the ITB Release Levers when turning the ITB Release Levers, or your hand may be
pinched.
b-4) Holding the 2 grips [a] with both hands, lift the Intermediate Transfer Unit approx. 40 degrees and then lower it to the lock
position (approx. 30 degrees).
18
b-5) Rotate the 4 Primary Transfer Roller Pressure Release Levers anticlockwise to disengage.
b-6) Holding the grip [a], pull the Release Lever [b] until it stops while lifting the Intermediate Transfer Unit. While pulling the
Release Lever, lower the Intermediate Transfer Unit until it passes through the lock position (approx. 30 degrees), and release
both hands (the Intermediate Transfer Unit will lower slowly).
[Caution] Do not insert your hands etc. into the Intermediate Transfer Unit or Intermediate Transfer Unit Frame when lowering
the Intermediate Transfer Unit.
b-7) While pushing the 2 Lock Release Springs [a], slide the Intermediate Transfer Unit toward the rear side until the lock is
released.
19
[Caution] Be careful not to get your fingers caught when sliding the Intermediate Transfer Unit toward the rear side.
b-8) Perform the work in the reverse order from the step b-3).

Ring marks on an image due to the foreign substance contamination in the developing assembly
[Symptom]
In the machines prior to the Countermeasure cut-in serial number in factory described below due to an inevitable mixing of foreign
particles, a faulty image called a ring mark may be output on the print.
[Cause]
The metal powder mixed into the developing assembly attaches onto the surface of the developing sleeve and brings a leakage
symptom to the drum. Toner attaches onto the leaked location and this leads to the aforementioned symptom.
[Service work]
When the above mentioned symptom has occurred, follow the steps below.
a) When the main unit is already installed.
1) Service mode (level 2) : COPIER>Option>IMG-DEV>ADJVPP-M/C/K, change the parameter from "-1" to "-4".
[Caution] As the ring mark has never been observed with yellow color, do not change the parameter of ADJVPP-Y from "-1".
2) Execute the auto gradation adjustment.
b) When the main unit is not installed yet.
Perform the following installation work to install the main unit.
1) Execute the service mode (level 1) : COPIER>FUNCTION>INSTALL>AINR-OFF.
2) Service mode (level 2) : COPIER>Option>IMG-DEV>ADJVPP-M/C/K, change the parameter from "-1" to "-4".
[Caution] As the ring mark has never been observed with yellow color, do not change the parameter of ADJVPP-Y from "-1".

Marks appear on the front side of the back face of one-sided print or of the first face of two-sided print
[Symptom]
Marks may appear on the front side [a] of the back face of one-sided print or of the first page of two-sided print.
The arrow [b] indicates the direction of feeding.
[Cause]
Paper dust or toner may attaches onto the pressure belt of the primary fixing assembly from the influence of the paper or toner
scattering inside the machine.
At that time, if the pressure belt displacement control is executed, the fixing belt comes in contact with the belt pressure shaft,
and paper dust and toner attach onto the belt pressure shaft.
When hundreds of thousands or more of sheets of paper has passed through the device, the paper dust or toner piled up on the
belt pressure shaft increases and it may move to the pressure belt during the pressure belt displacement control.
Paper dust and toner moved to the pressure belt attaches onto the paper, and this brings on the aforementioned symptom.
[Service work]
1) Remove the primary fixing pressure belt unit referring to "Disassembly/Assembly > Fixing System > Replacing the Primary
Fixing Pressure Belt Unit" in the service manual.
2) Clean the primary fixing belt pressure shaft and the adjacent shaft [1] with lint free paper moistened with alcohol [2].
3) Reassemble the primary fixing pressure belt unit in reverse order from the step 1).
4) Output the image having shown the symptom, and check that the symptom does not occur.
If the symptom does not improve, check other causes.

Strike mark on the fixing roller due to toner soiling
[Symptom]
Strike mark [a] may appear on the image. The symptom is easily found on a high density image such as halftone or solid image.
[Cause]
When printing, the upper tandem guide and paper interfere with each other. As a result, toner peels from the paper and
accumulates on the upper tandem guide. The above symptom may occur when a toner lump accumulated on the upper tandem
guide peels and falls, and then is transferred by paper and finally attaches to the secondary fixing roller.
[Service work]
1) Follow the steps in Service Manual "Disassembly / Assembly > Fixing System > Replacing the Secondary Fixing Roller,
Replacing the Secondary Fixing External Heat Belt, Replacing the Secondary Fixing Refresh Roller" and replace the Fixing Roller
(FL1-1152-000), the External Heat Belt, (FE3-1881-000) and the Refresh Roller Assembly (FM3-2876-000) in the Secondary
Fixing Assembly.
2) Check the upper tandem guide [a] and if toner is attached, follow the steps in Service Manual "Disassembly / Assembly >
Fixing System > Cleaning the Tandem Guide" and wipe the toner with lint-free paper soaked in alcohol.
3) Output the image having shown the symptom, and check that the symptom does not occur.
[Reference] At the time of regular replacement of the secondary fixing roller, check the upper tandem guide and wipe the toner
if any is attached.
