Figure 2-3-3
Notes: 1. The shaded area indicates the area where the laser beam can write.
2. T1 is the range 1mm toward the center from the right and left sides of the Letter size
regardless of the paper size specification.
3. T2 is the range 1mm toward the center from the leading edge of the paper (start of
/BD output) to the trailing edge of the paper. When the number of /BD pulse lines
(number of scan lines) is specified with a scan line number specification command
from the interface controller, the trailing edge of the T2 is where the /BD output for
the specified number of scan lines completes. When the number of scan lines is not
specified, the trailing edge of the T2 is where the paper top sensor (PS002) detects the
trailing edge of the paper.
