Step 1 Eliminating the Basic Causes of Misalignment

Find the answers to your questions about how to solve your problems�
Q�
Is the machine or paper located in a high humidity environment?
A�
Paper tends to expand when it absorbs moisture from a highly
humid environment� If this happens, the images may be printed in the
wrong position� For example, the image may be printed in the lower left
corner, rather than in the center as expected� Or, images printed on the
front and back of the paper may be misaligned�
Solution
• Keep the machine and paper in a room with a steady temperature and
humidity� If the temperature and humidity are unstable, it may cause the paper
to expand or shrink, resulting in misalignment of printed images�
• For the appropriate temperature and humidity, see the
Installation and Operating Environment Guidelines or the Specialty Media Handling Guide�
• Before you load paper, place the package of paper near the machine so it can fully acclimatize to the temperature
and humidity�
• Unwrap the paper immediately before you load the paper into the machine�
Q�
Is the paper cut correctly?
A�
If the paper is not uniform in size and
shape, the margins around the image may be
different on each page� If the paper is not cut
square, the images may be skewed when they
are printed�
Solution
• Use a different batch of paper that has been cut
correctly�
• If you cut the paper yourself, measure it and confirm
it is the correct size�
