Image Faults
Optimization of fixing pressure and fixing temperature when
envelops are fed
[Symptom]
When envelops pass the fixing assembly, the load is centralized on the overlapping points [a] on the reverse side of envelop.
Therefore an image having partial white spots may be output due to the occurrence of worn-out fixing belt surface or shaved
rubber of fixing roller surface. If the fixing pressure is greater, the overlapping points [a] may make impresses [b] on the front of
envelop depending of the type of envelop.
[Service work]
As
the measure of the above-mentioned symptoms, MN-CONT is graded up to v30.52 and D-CON is graded up to v30.31 for the
following 2 controls.
A) Optimization and segmentation of fixing pressure and fixing temperature for envelops.
B) Increase of changing range for fixing pressure adjusted values of envelops.
A) Optimization and segmentation of fixing pressure and fixing temperature for envelops.
The default value for fixing pressure is decreased and the default value for fixing temperature is increased. The paper weight is
classified into 6 ranges and each range has its specified default values for fixing pressure and fixing temperature.
This
Optimization and segmentation reduce the abrasions of fixing belt surface or fixing roller surface and then the image having
partial white spots will rarely occur.

B) Increase of changing range for fixing pressure adjusted value of envelops.
The changing range for the adjusted value table which is selected with User Mode [Adjust fixing pressure] is increased to make
the impress of envelop difficult to appear.
As the default value is changed from [-1] to [-3], the state of the impress will be improved gradually. On the other hand, if the
image has generous amount of toner deposit, it leads poor fixing capacity by changing the adjusted values.

Non-glossy streaks due to the peeled off tape on the separation
plate
[Symptom]
On the main body whose Countermeasure Cut-in Serial Numbers in Factory is earlier than the following number, non-glossy
streaks [a] image may occur with high gloss media or heavy media (200g or more).
The arrow indicates the paper feed direction.
[Cause]
The separation plate [1] in the fixing assembly [A] comes in thick and thin types. The tape affixed to the thicker separation plate
[1] comes off [a] from scuffing, then the fed paper comes in contact with the peeled off tape and leads to the above mentioned
symptom.
The arrow [b] indicates the paper feeding path.
[Service work]
As a countermeasure against the aforementioned symptom, replace the separation plate with the thinner type that reduces
scuffing of the tape even when a high gloss or heavy media is passed through.
To make this feasible, newly assign the fixing separation unit with the thinner separation plate, inner paper delivery assembly
and fixing base assembly as service parts respectively. The other type with thicker separation plate is also going to be newly
assigned as well. As to the newly assigned new type inner paper delivery assembly and the fixing base assembly, their fixing
separation units are removable. The fixing separation units of the old types are not removable.
If
the shape of the inner paper delivery assembly is as shown in the photo [A], replacing the fixing separation unit only is possible.
The photo [B] shows the shape of the old type inner paper delivery assembly.

From 1.6mm to 1.7mm pitch uneven density occurring when
coated sheets whose basis weight is 200gsm or more are
continuously output
[Symptom]
From
1.6mm to 1.7mm pitch uneven density [a] may appear in main scanning direction on the second sheet or later when coated
sheets whose basis weight is 200gsm or more are continuously output. The symptom is prominently seen on a black halftone
image. The arrow [b] indicates the direction of feeding.
[Cause]
Because
the paper feeding speed of fixing assembly is faster than the speed of secondary transfer unit, the media will be pulled
between the secondary transfer unit and the fixing assembly. Therefore, the vibration of fixing idler gear is transferred to the
scanner and that results in the above symptom.
[Service work]
When the above symptom occurs, adjust the fixing speed to minus side for every sheet in the management setting for media type
in user mode.
1) Have the customer log in from System Management Mode in user mode.
2) Go to Select Settings/Registration > Preferences > 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.
4) Select the paper type copied in the step 3) and then press "Details/Edit" button.
5) Select "Adjust Fixing Speed" and then press "Change" button.
14
[Reference] In case Adjust Fixing Speed 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) Change the setting value to minus side and press "OK" button.
The configurable range for the value is from "-20" to "+20". (Default: 0)
7)
Select the paper type which is set from step 2) to step 6) and output the image which had the symptom to make sure that the
symptom does not occur any more.
If the symptom does not improve, then check other factors.

Soiled image (Black dots) due to toner unable to be collected by
a scraper
[Symptom]
When printing with the machines manufactured before the following serial numbers, soiled image (black dots) [a] may occur at
the edge of papers (front or rear side) in 37mm intervals.
The arrow [b] indicates the feed direction.
[Cause]
The double-sided tape that secures the scraper [1] which collects waste toner has a shape where the edge of the glued portion
is narrower than the center of the glued portion. Thus depending on the force to affix the scraper [1] or the displacement of the
affixing position, in a high temperature/high humidity environment, the position of the edge may be displaced [b] depending on
the
force loaded in the direction of the arrow [a]. The above symptom occurs because toner cannot be collected in the area where
the sheet is displaced.
[Service work]
The developing assembly (black) is changed to the new type where the double-sided tape securing the sheet has stronger
adhesive.
