(10) Adjustment of the Image Leading Edge Erase Width
◆Requirement
• Ready a test chart (A3 or 11" × 17") as shown on the
left. Paint a 20 mm-long rectangle in black at the
center of the test chart along its leading edge as
shown. Adjust so that the erase width along the
leading edge of the painted area measures 0.5 to
6.5 mm.
•
Setting value range: 42 to 58
•
Movement equivalent to 1 step of setting value: 0.75 mm
•
Having a greater setting value results in a greater erase width.
•
Having a smaller setting value results in a smaller erase width.
◆Important
•
This adjustment must be made after the leading edge registration adjustment has been
completed.
1. Place the test chart face down on the Original Glass
and align its rear left corner with the marker on the
Original Width Scale on the left side of the platen.
Then, lower the Original Cover.
2. Make two single copies in full size mode (100 %) and
check for leading edge erase width on the second
