3 - 36
In this case, the image quality can be improved by adjusting the leading edge void width wider. Also, it
can be improved by changing the transfer bias ON timing using the setting code 08-841.
* When using the setting code 08-841 to improve the image quality, increase the value by one and
check the result. If the result is not sufficient, repeat the same procedure.
(The transfer ability for the paper leading edge shows a tendency as shown in the table below.)
* The transfer ability for the paper leading edge and the paper separation ability from the photo-con-
ductive drum are inversely related as shown in the table below.
Therefore, if the value is increased too much, this may cause the slight decrease of the paper sepa-
ration ability from the photo-conductive drum. So, when adjusting the value, be sure to check the
paper feeding as well as the image quality.
