Uneven density at 15.5mm intervals
[Symptom]
When a paper of 106gsm or more is used, uneven density at 15.5mm intervals [a] may occur on a high density image.
The arrow [b] indicates the direction of feeding.
[Cause]
If the developing cylinder [a] inside the developing unit is minutely eccentric, the distance between the developing cylinder and
the drum [b] gyrates and the above mentioned symptom occurs.
[Service work]
1) Go to Service mode (Lv2) > Mode List > COPIER > Option > IMG-DEV > and change the setting value of "ADJ-VPPN" to "1".
The range of setting is from "-1" to "4" ("0" by default).
Increment the developing AC bias by 100V by changing the parameter.
[CAUTION] Increment of the parameter may generate image fogging, ring marks and uneven density at 15.5mm on a halftone
image.
2) Output the image having shown the symptom, and check that the symptom does not occur.
If the improvement of the symptom is not good enough, inclement the parameter of the step 1) by "1" at a time up to when it
reaches "+4" and see how the result is.
3) Output the image having shown the symptom, and check that the symptom does not occur.
If the symptom does not improve, revert the parameter of the step 1) to its original value and check other causes.
