TCRU Procedures: Further Reducing the Off-Registration for Side 1 and Side 2
Adjustment Method
Adjust the Side 2 image position/magnification so that it is aligned with Side 1. Do not adjust Side 1.
Perform continuous printing for 10 sheets of the template. Use the 6th sheet to perform the following adjustment.
Perform a visual check of the 4th, 5th and 6th sheets to confirm that there is about the same amount of off-registration. If there is discrepancy in the amount, perform adjustment using a template which averages the discrepancy.
Adjustment Items
[Adj Image Position of Side 2 With Feed]
[Adj Image Position of Side 2 Across Feed]
[Adj Magnification of Side1 With Feed]
[Adj Magnification of Side1 Across Feed]
Adjustment Procedures
Follow the steps below to adjust the image position in the perpendicular direction and feed direction.
Perpendicular direction
Adjust [Adj Image Position of Side 2 With Feed] so that the Side 2 center line [A] is aligned with the Side 1 center line [B].
Feed direction
Adjust [Adj Image Position of Side 2 Across Feed] so that the image on the side 2 leading edge is aligned with the side 1 image.
Follow the steps below to adjust the image magnification in the perpendicular direction and feed direction.
Perpendicular direction
Adjust magnification for [Adj Magnification of Side1 With Feed] so that the gap between arrows on the side 2 leading edge is aligned with the gap between arrows on side 1.
*Magnification adjustment reference: A3 short direction (297mm)
0.025%: near equal 0.1mm, 0.1%: near equal 0.4mm
The adjusted value is updated uniformly in the up/down direction.
Feed direction
Adjust magnification for [Adj Magnification of Side1 Across Feed] so that the image on the side 2 trailing edge is aligned with the side 1 image.
*Magnification adjustment reference: A3 long direction (420mm)
0.025%: near equal 0.07mm, 0.1%: near equal 0.3mm
The adjusted value is update to the trailing edge.
