Procedure of [Both Sides Adjust]
The following shows the procedure for the [Both Sides Adjust].
Checking the reference position of the printing side
To determine the misalignment of printing position, the adjustment of the reference position required on the main body side must be completed.
Before performing the [Both Sides Adjust], check the adjusted value of the reference position and make adjustment as needed.
The following items of [Adjustment] - [Machine Adjustment] - [Printer Adjustment] on the [MACHINE] screen are adjustment items that need to be checked:
[ Restart Timing Adjustment] -> Restart Timing Adjustment: Adjusting the Image Position of Lead Edge in Paper Feed Direction in the Printer
[ Centering Adjustment] -> Centering Adjustment: Adjusting the Image Position in the Crosswise Direction in the Printer
[ FD-Mag. Adjustment] -> FD-Mag. Adjustment: Adjusting the Magnification in Paper Feed Direction in the Printer
[ CD-Mag. Adjustment] -> CD-Mag. Adjustment: Adjusting the Magnification in Crosswise Direction in the Printer
Adjust the front side in the following order, and then adjust the back side in the same order.
[ FD-Mag. Adjustment] - [CD-Mag. Adjustment] - [Restart Timing Adjustment] - [Centering Adjustment]
The adjustment for the reference position of the print side is an advanced adjustment. Contact your service representative in advance of the adjustment.
Performing [Both Sides Adjustment] per Tray
The adjustment can be made by either of the following three methods:
[Gap] adjustment: the method used for aligning both sides with correction of the back side magnification and print position based on the front side ones. ->Gap Adjustment
[Chart Adjustment]: the method used for aligning both sides with correction of the magnification and print position of both front and back side. ->Chart Adjustment
[Zoom]/[Image Shift] adjustment: the method used for fine adjustment after [Gap] adjustment or [Chart Adjustment], or the method used when the amount of misalignment between both sides is figured out. ->Zoom/Image Shift Adjustment
It is convenient to adjust the back side magnification and print position by [Gap] adjustment after adjusting the front side ones by [Chart Adjustment] or [Zoom]/[Image Shift] adjustment.
If the paper is bent or wrinkled when printing, adjust the [Registration Loop] amount before performing [Gap] adjustment, [Chart Adjustment] or the [Zoom]/[Image Shift] adjustment. For details, refer to Adjustment of Registration Loop.
