10. Place the original on the DF and make a test copy.
If the copy image is different from the original, run maintenance item U070
"Adjusting the DF magnification," U071 "Adjusting the DF scanning timing" or U072
"Adjusting the DF center line" as necessary (see the SRDF service manual).
11. If the leading or trailing edge of the copy image is skewed (the lateral squareness is
not correct), adjust the lateral squareness of the DF.
Caution:
• Before performing this adjustment, output a VTC-PG2 pattern in maintenance item
U993 to use as the original for the adjustment.
• Adjust the amount of slack in the paper (see page 3-3-22) and the lateral
squareness (reference) (see page 3-3-35) first. Check for lateral squareness of
the copy image and if squareness is not obtained, adjust the lateral squareness of
the DF.
