Procedure of [Both Sides Adjust]

The following shows the procedure for the [Both Sides Adjust].

1. 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.

   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.

   The adjustment can be made by either of the following four methods: (For bizhub PRESS C1070P / bizhub PRESS C71hc, [Scan Meas.] cannot be used for adjustment.)

   • [Scan Meas.] adjustment: the method used for aligning both sides with correction of the back side magnification and print position based on the front side ones. Will automatically adjust the both side adjustment with a scanner functions of this machine.->Scan Meas. Adjustment

   • [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 [Scan Meas.] adjustment, [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 [Scan Meas.] adjustment, or [Gap] adjustment after adjusting the front side ones by [Chart Adjustment] or [Zoom]/[Image Shift] adjustment.

   You need not perform both of the [Scan Meas.] and [Gap] adjustment.
