Adjusting [Perpendicularity]
At [Perpendicularity], you can adjust both the front and back sides, but the adjustments will affect all
trays.
1.
Check the chart, and measure the amount (mm) of misalignment in the image position.
Use the following formula to obtain the amount of perpendicularity misalignment, with the leading
edge of the paper facing upward, "A" representing the lead registration length (mm) of the left edge
and "B" representing the lead registration length (mm) of the right edge.
Amount of perpendicularity misalignment (mm) = (A-B) x 216 / (main scanning direction [mm] - 20)
