Cautions after the completion of the adjustment
Nothing in particular.
Remarks
• Enter the value mentioned in the procedures or one within the recommended value range for the adjustment.
Otherwise, it may cause a loss in copier performance, including degradation in the image quality and reduction
in the life of the consumables.
• The desired image quality may not be obtained, depending on the type of paper used. In this case, use the
recommended paper and then print or adjust the image quality.
• If printing on another type of paper causes a problem with the image quality after the adjustment, return the set
values (for 05-234 to 239) to the default (set value: 5) and then perform the adjustment again.
• The adjustment will make up for the gap in the image quality and density between the front and back of the
paper in duplex copying/printing. Particularly, if the image on the back is lighter than on the front, the image
quality may be improved by increasing the set value for the transfer roller bias output.
• When replacing any consumable, refer to the relevant information in the Service Manual and Service Handbook.
