Before the adjustment After the adjustment
The copy image looks light on thick paper. The copy image looks darker and sharper even
on thick paper.
Explanation
When a copy is made on thick paper in thick paper mode, the copy image sometimes looks light. In thick paper mode,
the amount of toner used is reduced in advance, in order to avoid a toner fixing problem. Adjust the amount of toner
used, while checking the toner fixing, in order to obtain a dark and sharp copy image on thick paper.
Procedure
* The adjustment is performed by the service technician only.
(1) Enter adjustment mode [05]. Change the values for codes [1613 to 1616] to adjust the amount of toner used.
• The code to use varies, according to paper mode. Adjust the value for the [05] code corresponding to
paper mode for which you would like to improve the image quality and increase the value to obtain the
copy density that the user desires.
