"Polygon printhead mechanical registration adjustment" on page 377
The printer skew specification calls for image skew on the registration sheet to be one dot (0.5mm) or less delta between
the left and right alignment indicators for the top and bottom margins. Some variation occurs from sheet to sheet, so
a few sheets can be printed to get an improved feel for the skew. Also, top and bottom margin registration adjustments
may be required before or after making skew adjustments. Use the diagrams below to help choose which adjustment
is appropriate.
The margin registration page is used to evaluate skew. The Quick Test Page can be obtained by following these steps.
