1.6 To Adjust Printing Positions on Front and Back Sides in
the duplex mode
 Explanation
The printing positions on the front and back sides of business cards may deviate. The amount of this
deviation can be reduced with image position or image distortion adjustment.
 Procedures
The service technicians must perform all adjustments in accordance with the procedures below.
(1) Overview of adjustment
The adjustment is divided into 3 major categories noted below. The points for each adjustment are
as follows:
(a) Image position adjustment: Adjust values as closely as you can to the target value (±0).
(To make printing positions as precise as possible)
(b) Image distortion adjustment: Adjust the image distortion that is not susceptible to the self-
diagnostic codes by using the hardware.
(To make printing positions as precise as possible)
(c) Fine image positions adjustment: Adjust the image positions finely to place the images on
both sides in their optimal positions.
(2) (a) Image position adjustment
Refer to the “6.1.7 Image dimensional adjustment at the printing section” of the Service Manual and
adjust the image positions by approximating values from [A] to [F] below to a target value (±0) as
closely as possible.
