■ Squareness Adjustment

1) Create a test sheet, place it on the ADF, and make a copy of it.
2) Check the image squareness at the leading edges of the test sheet and copied paper.
Measure dimensions A and B and obtain the difference between them. Adjust the
squareness so that the amount of skew is within specification.
