Alignment Adjustment information

When printing duplex jobs and using different media types (including paper type, weight,
and coating/uncoating), the output may require specific handling by the machine as it
is moving through the paper path. With certain media types and duplex jobs, the images
on side 1 and/or side 2 may be misregistered, skewed, perpendicularly misaligned, or
stretched; this is where alignment procedures can be used to eliminate these type of
issues.
Alignment adjustment procedures allow you to:
• Make adjustments to the image based on the alignment output of a document.
Various adjustments can be modified such as: print position (registration),
perpendicularity, skew, and magnification.
• Make adjustments when the position of the output image is misaligned or skewed.
This may be a result of paper expansion or contraction, cutting inaccuracy, or paper
storage conditions. To compensate for this scenario, the alignment adjustment feature
can be used to adjust the image alignment.

Things to consider when creating/using an alignment procedures

When creating alignment procedures for side 1 and/or side 2 prints, be aware of the
following:
• Side 1/side 2 images may be misregistered because the paper is not the exact same
size. It may vary slightly, with differences of +/- 1 mm, causing the image to be
misregistered. To reduce the possibility of size differences, it is recommended that
you use paper from the same lot when running duplex jobs.
• During the fusing process, the heat and pressure applied to the paper causes the
paper to stretch. If the images on sides 1 and 2 are the same size, the stretching of
the paper may cause the image on side 1 to be slightly larger than the image on side
2.
Creating an alignment adjustment procedure for these types of jobs allows you to reduce
or eliminate the images being larger on side1 than on side 2 prints.

Alignment Adjustment options

Alignment Adjustment includes the following options:
• Name: Provide a name specific so that later recall is not an issue.
• X and Y Print Positions: Adjust the position of the image in lead edge/paper feed
direction (X position) or in the side edge/vertical direction (Y position). The X/Y Print
Position often is referred to as registration.
