area
Notes: 1. The shaded area indicates the area where the laser beam can write.
2. T1 is the range between 1mm from the right side and 1mm from the left side of the Letter size. It
is not dependent on the specified paper size.
3. T2 is the range between 2 mm from the leading edge and the trailing edge of the paper. (The
output of the /BD signal starts on the leading edge.) If the number of /BD pulse lines (number of
scan lines) is specified by the interface controller with the command, the trailing edge will be
where the output of the /BD signals completes. If the number of scan lines is not specified, the
trailing edge will be where the paper top sensor (PS002) detects a paper-out.
