34 - 0001 Image position correction
patch detection alarm 1
Movement: None
Cause:
The detection data of the average value of the image
position correction patch pattern has exceeded the
permitted range.
• Scraches on the ITB
• Failure of the photosensitive drum
• Noise due to contact failure of the ITB guide (The
ITB unit is not installed correctly.)
Measures:
1. Check whether the color image is formed correctly
for 4 colors.
a. Perform test print in the following condition.
COPIER>TEST>PG>TYPE: 5
Output one sheet for each color in the paper of
LTR/A4/A3 size (more than 290mm in a horizontal
scanning direction).
b. Check the following points.
• Check whether the image is formed in the printing
field except a margin. Check whether the image
density is not low.
• Check whether an unexpected image is not formed.
If a correct image is not formed, check the following
points.
• Developing assembly: Check whether dirt is not
applied to the developing.
• Drum: Check whether dirt is not applied to the drum.
Check whether there are no scratches on the drum.
• ITB cleaning unit: Check whether an ITB cleaning
failure has not occurred. (Check whether the
previous image does not remain.)
• Check whether there are a lot of scratches or dents
on the ITB or not.
Based on the checking results and frequency
of occurrence of the alarm, make a judgment of
whether or not to replace the corresponding parts.

34 - 0002 Image position correction
patch detection alarm 2
Movement: None
Cause:
The image position correction patch pattern cannot be
detected at all.
• Failure of the patch sensor
• Failure of the shutter
• Image failure
1. 1. Check whether the color image is formed correctly
for 4 colors.
a. Perform test print in the following condition.
COPIER>TEST>PG>TYPE: 5
Output one sheet for each color in the paper of
LTR/A4/A3 size (more than 290mm in a horizontal
scanning direction).
b. Check the following points.
• Check whether the image is formed in the printing
field except a margin. Check whether the image
density is not low.
• Check whether an unexpected image is not formed.
If a correct image is not formed, take measures to be
taken for prevention of an image failure. (Check the
developing assembly and drum unit.)
• Developing assembly: Check whether dirt is not
applied to the developing.
• Drum: Check whether dirt is not applied to the drum.
Check whether there are no scratches on the drum.
• ITB cleaning unit: Check whether an ITB cleaning
failure has not occurred. (Check whether the
previous image does not remain.)
• Check whether there are a lot of scratches or dents
on the ITB or not.
Based on the checking results and frequency
of occurrence of the alarm, make a judgment of
whether or not to replace the corresponding parts.
2. Damage or dirt of/on the patch sensor
a. Check whether the shutter of the patch sensor
operates correctly.
b. Check whether dirt is not applied to the patch sensor.
If dirt is applied, clean the sensor surface
with alcohol. After cleaning, execute patch
light intensity correction and base correction
(COPIER>FUNCTION>MISC-P>PT-LPADJ).
c. If the problem is not eliminated even after cleaning,
replace the registration patch sensor unit.
d. Check whether shorting has occurred to the patch
sensor harness.
If it occurred, replace both of the harness and the DC
controller interface PCB. (It is necessary to replace
the PCB because the DC controller interface PCB
burns when shorting occurs.)
