The Workflow of Both Sides Adjust

2.2 The Workflow of Both Sides Adjust
Perform the Both Sides Adjust in the following order:
1. Checking reference positions on the print side
In order to determine the misalignment, the adjustments of the reference positions, which are required on the
main body, must be completed.
Before performing the Both Sides Adjust, verify the adjustment values of the reference positions and modify
them if needed.
NOTICE
The adjustments of the reference positions on the print side are advanced adjustments. Contact your service
representative in advance of the adjustments.
The adjustments of the reference positions on the print side can be accessed from [01 Machine Adjustment]
on the Adjustment Menu Screen.
First, make adjustments for the front side in the following order:
-
[01 Magnification Adjustment] - [01 Printer FD-Mag. Adj. (Side 1)]
-
[01 Magnification Adjustment] - [03 Printer CD-Mag. Adj. (Side 1)]
-
[02 Timing Adjustment] - [01 Printer Restart Timing (Side 1)]
Then, make adjustments for the back side in the following order:
-
[01 Magnification Adjustment] - [02 Printer FD-Mag. Adj. (Side 2)]
-
[01 Magnification Adjustment] - [04 Printer CD-Mag. Adj. (Side 2)]
-
[02 Timing Adjustment] - [02 Printer Restart Timing (Side 2)]
When the above adjustments are completed for both front and back sides, make the following adjustment:
-
[03 Centering Adjustment] - [01 Printer Centering Adjustment]
2. Performing the Both Sides Adjust for each tray
The adjustment can be made by the four methods given below. (Scan Measurement Adjustment is not avail-
able for bizhub PRESS 1250P.)
-
Scan Measurement Adjustment: This is a method to align the front and back sides by adjusting the
magnification ratio and printing position of the back side with reference to the front side. You can per-
form the Both Sides Adjust automatically by using the scanner function of this machine.
-
Gap Adjustment: This is a method to align the front and back sides by adjusting the magnification ratio
and printing position of the back side with reference to the front side.
-
Chart Adjustment: This is a method to align the front and back sides by adjusting the magnification ratio
and printing position of the front and back sides.
-
Zoom/Image Shift Adjustment: This is a method to make fine adjustment after the Scan Measurement
Adjustment, Gap Adjustment, or Chart Adjustment or to align the known gap between the front and
back sides.
- It is practical to first perform the Chart Adjustment or Zoom/Image Shift Adjustment to adjust the
magnification ratio and printing position of the front side, then perform the Scan Measurement
Adjustment or Gap Adjustment to adjust those of the back side.
- You need not perform both of the Scan Measurement Adjustment and Gap Adjustment.
- You can change the default screen for the Both Sides Adjust Screen. Contact your service represent-
ative, if desired. (The Scan Measurement Adjustment Screen cannot be specified as the default screen
for bizhub PRESS 1250P.)
2.2.1

Scan Measurement Adjustment

Adjust the magnification ratio and printing position of the back side with reference to the printing position of
the front side. The magnification ratio and printing position of the back side are automatically adjusted by
using the scanner function of this machine to measure the gap amount in printing position of the back side
to the front side. You do not need to measure the gap amount with a scale. The adjustment is available for
paper of all sizes which can be used with this machine.
Print out 1 to 20 sheets of the adjustment chart having both front and back sides printed, and scan them 4
times per sheet. The average value of gap amounts in printing position of the back side to the front side,
which can be obtained by scanning up to 20 sheets of the adjustment chart, will be calculated in order to
adjust the magnification ratio and printing position of the back side.
